Support grows for BRT in eastern Montgomery, but councilmembers are undecided

Montgomery County is currently deciding what projects to prioritize for its share of state transportation funds. But elected officials are divided over whether to support building new interchanges along Route 29 in East County, or a Bus Rapid Transit line instead.

Tomorrow, the County Council will discuss its transportation priority letter, which requests funding for specific projects from the state. The council's Transportation and Environment committee has recommended taking a progressive shift to prioritize more bicycle, pedestrian, and transit projects.

Led by chair Roger Berliner and at-large councilmember Hans Riemer, the committee prioritized funding to extend the Corridor Cities Transitway to Clarksburg, WMATA's Priority Corridors bus network, and funding to implement bicycle-pedestrian priority areas throughout the county. They also voted to remove three out of four proposed new interchanges on Route 29 in White Oak and Burtonsville.

Several interchanges have been built on the corridor between Silver Spring and Burtonsville in recent years, creating a partially closed-access highway between Route 198 and New Hampshire Avenue that narrows down to a typical, six-lane arterial south of New Hampshire Avenue, where Route 29 approaches downtown Silver Spring.

There have been plans on the books for years to add four additional interchanges north of White Oak, at Fairland and Musgrove roads, Tech Road, Stewart Lane, and Greencastle Road, which has the support of County Executive Ike Leggett. The total price tag? $344 million.

The problem is, the real bottleneck on Route 29 is south of all these intersections in the Four Corners neighborhood, where drivers queue to get on the Beltway. State and county planners know they will never widen Route 29 through Four Corners, meaning new interchanges will only speed more commuters to the bottleneck faster. The interchanges will also make pedestrian connections across the highway more difficult, while increasing the flow and speed of traffic in areas like Four Corners, reducing pedestrian safety.

That's why the council committee and the Planning Board both recommended removing additional interchanges from this year's list. Route 29 is one of the 10 corridors in the county's newly-approved BRT network, and Planning Department staff who ran models on the corridor suggested implementing BRT first, and then reviewing whether the interchanges are still needed. They estimate that an 11-mile BRT line between Silver Spring and Burtonsville would cost $351 million, similar to the three interchanges.

While Bus Rapid Transit is not yet ready for construction on Route 29, requesting funds for the three interchanges now would absorb a significant amount of state funds for years to come, making it more difficult to fund needed, high-quality transit in the corridor in the future.

A chart comparing the County Executive's proposals and committee recommendations is on the last page of the council packet. At-large councilmember Nancy Floreen wants to see all four interchanges on 29, while the County Executive wants two: Fairland/Musgrove and Tech. It's unclear where the rest of the Council stands on the issue, especially newly-appointed interim Councilmember Cherri Branson whose district (District 5) includes Route 29.

VA legislative update: Bike safety bills advance, while some still try to limit Northern Virginia

As Virginia's legislative session continues, House Republicans are still trying to take local planning authority from Northern Virginia cities and counties. Two bicycle safety bills have moved forward. And Hampton Roads may get a regional transportation authority of its own.

Bike bills seek to prevent "dooring"

Two bicycle safety bills have passed the Senate and are heading to the House of Delegates, including a bill that would require three feet of clearance when passing a cyclist. Another bill, Senate Bill 225, codifies that a car driver or passenger must ensure that the road is clear before opening their car door into traffic. And the House of Delegates passed HB 82, which specified that non-motorized transportation was included in the law that prohibits drivers following too closely.

However, two road safety bills that would have clarified a driver's duties to pedestrians in crosswalks were defeated in the House.

Delegates rewrite bill stripping Northern Virginia's ability to plan for itself

In our last update, we talked about HB 2, which would reduce Northern Virginia's ability to plan its own transportation projects. It's been significantly rewritten to put transit projects on more equal footing with roads and highways.

It will allow the state to evaluate projects on economic development, safety, accessibility, and environmental quality in addition to congestion relief, which would have been the only factor under the previous bill.

Meanwhile, HB 426, from Chantilly Republican Jim LeMunyon, has been tabled. It called for a "study" of transportation options on I-66 that only included more lanes for cars. It's unlikely that it will come up again this year.

But Delegate LeMunyon did get a House Bill 793 out of committee. That bill would have VDOT recommend specific transportation projects to the groups that plan these projects in Northern Virginia. Bills like this want to ensure that there's always someone advocating for highway projects that local governments may have already said they are not interested in. And this one violates the spirit of last year's transportation bill, which allowed Northern Virginia counties to plan for more public transportation solutions to congestion rather than pursuing a strategy that only focuses on newer and wider roads.

Another bill that we covered and is aimed at pushing a transportation solution that local counties may not want is House Bill 1244 from Delegate Tom Rust (R-Herndon), which would study and likely advocate for another highway crossing of the Potomac River as part of the Outer Beltway. It's been referred to the appropriations committee.

And HB 957, which would delay giving the state more control over VRE's executive board, passed the House. The bill initially called for repeal but this delay means that repeal can be considered again next year.

Good news for red-light cameras, Hampton Roads

The Hampton Roads area may soon be getting a local transportation planning authority similar to the Northern Virginia Transportation Authority with HB 1253, which has moved out of committee. This may be a benefit to Northern Virginia since such a group could bolster the argument that transportation decisions can be answered effectively by local governments.

Meanwhile, House Bill 973, which would have repealed localities' authority to install red light cameras, has been defeated.

We'll keep you updated on what happens to these bills.

Self-driving cars are coming, and they could change everything we know about cities

Autonomous, self-driving vehicles are getting more attention from the media, but little from transportation planners. Given the technology's potential impacts on our transportation network, it's time for planners to start thinking about it.

As the technology advances, mainstream media now treat self-driving cars with seriousness and respect, as do business advisors like KPMG. Developers are designing self-driving car use into future retirement communities, while carmakers like Mercedes advertise passive "self-driving" safety features. Analysts predict that completely autonomous cars will be on sale by 2020.

Self-driving cars have the potential to reduce both car crashes and traffic congestion, and to use wasted time driving for work or entertainment. These are benefits usually attributed to transit; as a result, autonomous vehicles could strengthen arguments for designing for more cars in our cities and suburbs, instead of more pedestrians, cyclists, and placemaking.

Transportation planners aren't talking publicly about driverless cars

By contrast, online searches for "transportation planning" and "self-driving cars" turn up thoughtful, if skeptical reviews by urbanists Todd Litman and Jarrett Walker; a sober, academic summary of key issues by the Eno Center for Transportation; and a thorough debate from 2011 on the issue here on GGW; and an article from Governing Magazine that exemplifies the public preoccupation with regulating driverless cars rather than planning and policy issues.

There isn't a lot of evidence of transportation planners at public agencies giving serious attention to the matter, at least not publicly. A recent blog entry from Bacon's Rebellion also concludes that transportation planners are not paying attention. Though, to be fair, the topic was covered at a recent Florida Department of Transportation conference and the Transportation Research Board a few weeks ago.

Self-driving cars address many of the safety and travel efficiency objections that Smart Growth advocates often make about road expansion, or the use of limited street space. As a result, planners and placemaking advocates will need to step up their game.

They need to better define in what environments bike- and pedestrian-oriented designs are still appropriate even when we can solve our congestion problems with self-driving cars. They need to promote street and intersection that can work for bikes and pedestrians as well as for self-driving cars; and to make a strong cases for Smart Growth and TOD that are based on diverse benefits, not just on the ability to move people.

Capital planning decisions last for thirty years and beyond. The officials responsible for parking lot and garage building, transit system growth, bike lane construction, intersection expansions, sidewalk improvements, and road widenings need to analyze quantitatively how self-driving cars could affect their plans, and to prepare alternatives in case things change.

How could self-driving cars disrupt the planning process?

Here are two examples of situations where planners may need to adapt to self-driving cars:

Self-driving cars coupled with "smart intersections" that communicate with vehicles to let them pass without traditional stoplight timing could result in less congestion, but may speed up cars in places where cyclists and pedestrians are competing for space. The cars will be faster, but also safer to be around. The question is whether a more efficient auto network outweighs the negative impacts to other parts of the urban environment.

They may also make car use more competitive with bus transit in low-density settings and may erode the demand and need for transit (and paratransit). On the other hand, changed transit economics resulting from driverless buses could mean that extending transit into new areas will make more economic sense in the future than it makes today.

Ways to prepare for self-driving cars

So, what could the region's planners do now to anticipate the potentially sweeping changes that self-driving cars will cause? How can planners today insure that scarce infrastructure dollars are spent on things that might be less needed in the near future?

For example, if intersections can handle more vehicles per hour with self-driving cars than with human-driven cars, they may not need to be widened. Or if transit commuters can get to the station in a self-driving car, park-and-rides may not be necessary, because the car will just drive itself back home.

First, land use, highway, and transit planners should simply acknowledge the issue. They should begin to define how large different impacts may be, when those impacts are likely to occur, what the range of public responses will need to include, and when those public responses may have to start occurring.

Self-driving cars will change patterns of car ownership and travel. Planners need to examine how travel forecasting tools that are based on current patterns of car ownership and use will need to change to adapt to new statistical relationships between population, car ownership, trip-making, car-sharing, and travel patterns.

Because cars that can drive themselves won't stay parked all day, builders and regulators should think about how new parking structures should be designed for adaptive reuse if future parking demand declines.

State and local DOTs should measure how smart intersections could increase the number of vehicles that can use an intersection per hour, and how to design roads and intersections that work for self-driving cars, as well as pedestrians, bicyclists, and the creation of public spaces.

Finally, the region's transit agencies should study how driverless operations could affect operating costs for bus, rail, and paratransit services, and should update their long-range capital and operating needs forecasts to reflect what they learn.

Many aspects of the self-driving car world remain in doubt. That is not, however, a reason to avoid thinking about how to benefit from the capabilities that self-driving vehicles offer. Even if planners are only able to do general studies rather than detailed forecasts, that would still be a useful exercise. Understanding how to adapt our communities for the benefits and challenges of self-driving cars would be a huge step forward.

Fix it first, then upgrade, says new regional transportation plan

The National Capital Region Transportation Planning Board approved the draft Regional Transportation Priorities Plan two weeks ago. It advocates a "fix it first" approach that directs resources towards keeping the transportation assets we have in good shape, rather than building massive new facilities that may be costly to maintain.


Image from MWCOG.

The plan is a significant victory for smart growth advocates because it doesn't call for building any new highways. Maintaining Metro is the highest-scoring strategy overall. The plan calls for new transit facilities including both streetcar and bus rapid transit (BRT) lines, potentially using new express toll lanes on existing highways.

It also recommends capacity improvements like expanding Metro capacity in downtown DC, and focusing growth around existing transportation hubs and employment centers, offering more alternatives to driving. However, it relies on elected officials in local jurisdictions to make it happen.

The plan's supposed to inform future updates to the region's Constrained Long-Range Transportation Plan (CLRP), a more specific list of recommended capital investments, including this year's update. The CLRP's existing baseline includes the Silver and Purple lines, the planned DC streetcar network, and Arlington's Columbia Pike and Crystal City streetcars.

But first, local governments need to invest in the transportation infrastructure we already have. "The success of all other strategies to improve transportation in our region relies on an existing system that functions properly and is safe," the plan states. That includes Metro trains that run reliably and aren't overcrowded, bus stops that are easy to get to, roads and sidewalks that are smooth, structurally sound bridges, and efficient traffic signals.

Another key aspect of the plan is its focus on the region's activity centers, places like downtown DC or Bethesda that are walkable, bikeable, and well-served by transit. Simply directing more growth to these places can reduce car trips across the region. More people would have the opportunity to live or work there, while those who still chose to live elsewhere would have more options for getting to activity centers.

As MWCOG Principal Transportation Planner John Swanson put it, "We don't just focus on supply-side additions to the system, but also on managing demand."

Creating more activity centers is one of five central long-term strategies of the plan. The others are adding more capacity on the existing transit system, enhancing circulation within activity centers, encouraging BRT and other cost-effective transit services, and more express toll lanes.

At a press event January 15, Swanson emphasized that the Regional Transportation Priorities Plan is part of on ongoing planning process. It "shows why land use matters and why a lot of little decisions like [building better] bus stops matter," Swanson added. "If they aren't accessible and attractive, other work is for naught."

The TPB recommends focusing on "modes that can move more people at lower cost." The plan generally avoids citing specific projects or locations of concern. Rather, it's intended as a guide for state, county, and municipal officials as they determine which transportation projects deserve a share of their limited budgets.

Whether the vision comes true or not will depend on the elected leaders of the member jurisdictions. It will also require restoring citizens' trust in their government, meaning government must demonstrate that it is taking citizen input seriously and is getting the most bang for taxpayers' buck.

Among its other specific suggestions:

  • Local governments should help Metro reach its state of good repair goals outlined in Metro Forward.
  • Give Metro the resources needed to add capacity, including by adding more eight-car trains and increasing pedestrian flow capacity at constrained stations like Union Station.
  • Enhance and expand commuter rail service, primarily by addressing its two biggest constraints: limited capacity at Union Station and over the decrepit Long Bridge, the region's only crossing of the Potomac for commuter, intercity passenger, and freight trains.
  • Make major investments in relatively inexpensive pedestrian and bicycle infrastructure. It cites the District's success with new bike lanes and expanding Capital Bikeshare, and says adequate sidewalks and crossing signals are still lacking in much of the region.
  • Alleviate bottlenecks in the highway network by building new on- and off-ramps, extra turn lanes, and adding lanes in limited cases.
  • Grow the network of electric car charging stations to incentivize their use.
  • Make the road network safer and more efficient by such often-overlooked strategies as providing more real-time information to drivers, and by updating existing traffic laws, particularly to offer more protection to pedestrians and bicyclists.
The plan reflects and builds upon the work of the late Ron Kirby, the former MWCOG transportation planning director whose shocking murder in his home two months ago remains unsolved. The document is dedicated in his memory. Kirby chose not to pick sides in the more roads vs. more transit tug-of-war, but he was willing to say we should fix things first.

The TPB's next step is to disseminate the plan to both elected and administrative officials in all member jurisdictions and explain how it works. The plan highlights broad agreement at the regional level, and gives jurisdictions a framework for decision-making.

If it agrees, for example, that maintaining the existing system is the top priority, then its practices should reflect that. Thanks to language in a resolution the TPB adopted on January 15, the RTPP will guide DC, Maryland, and Virginia when they propose projects for inclusion in the CLRP.

"This work fits into a broader picture of what people are asking for," said Todd Turner, TPB member and Bowie city councilmember. "[Once people] see the impact of funding decisions on them, they become more supportive."

Read together with MWCOG's Region Forward plan, its Climate Change Report, and its Activity Centers map, the RTPP should guide the region to a better-managed, more transit-oriented, and more sustainable transportation future.

VA legislative update: Hybrid tax going, but bills to limit Northern Virginia remain

As the Virginia legislative session continues, lawmakers in Richmond have agreed to remove the hybrid car tax, and successfully defeated an attempt to take away Northern Virginia's ability to plan and fund its own transportation projects. But several destructive bills, including one that could force the state to widen I-66 in Arlington, are still on the table.

Hybrid car tax poised for repeal

Several lawmakers introduced bills to repeal a tax on the sale of hybrid cars, which the state passed last year. One such bill has now passed both houses and Governor Terry McAuliffe says he will sign it.

The original bill's justification was to make sure that hybrid car owners who use less gas, and thus pay less in gas taxes, still contribute to maintaining state roads. But its critics contend that the $64 tax is an inefficient way to make up for the lost revenue and unfairly punished hybrid drivers who are helping the environment by using less gas.

Attempts to limit Northern Virginia's choices narrow

Legislators have tabled several bills that sought to restrict the power of the Northern Virginia Transportation Authority (NVTA), which selects and funds transportation projects in that area. Instead, Republicans want Richmond to decide what gets built there, especially if it involves widening and building new highways.

Meanwhile, House Bill 658, sponsored by David LaRock (R-Sterling), would limit "transit, rail, and public transportation" to get at most 25% of Northern Virgnia's transportation funds. Not only is that an arbitrary standard, but it ignores how transit is already moving people and reducing highway congestion.

This proposal could prevent good transit projects from happening. If the region wants to ramp up a major new Metrorail, light rail, streetcar, or bus rapid transit project and spend more in one year than another, this cap would severely limit that ability. Besides, Northern Virginia should be able to choose how much to spend on different transportation priorities as it sees fit.

Bill would rate transportation projects on "congestion reduction"

Meanwhile, the legislature is still debating HB 2, which would require that the state pick transportation projects based on how much they are "expected to provide the greatest congestion reduction relative to cost." This relies on defining congestion solely as how many cars can move through an area, which automatically puts public transit at a disadvantage.

By its very nature, transit doesn't involve moving cars, and often requires a higher initial investment than a road project of comparable size. This proposal also ignores the ancillary benefits of transit, like lower pollution and the ability to tie transportation to land use, which can reduce overall car trips and conserve land.

"Study" bills push wasteful highway projects

A few bills require the Virginia Department of Transportation (VDOT) to conduct studies of highway projects their authors really want to see built. HB 426, by Jim LeMunyon (R-Chantilly) demands a study of adding extra lanes (that aren't subject to HOV restrictions) on I-66 inside the Beltway in Arlington and Falls Church.

The original bill would have forced the I-66 widening to be part of VDOT's capital plan. LeMunyon changed it to only require a study, which means that even if it passes, it wouldn't necessarily mean the project happens. However, once a study gets finished, it's a lot easier for a sympathetic future administration to turn it into reality, and gives project supporters something concrete to push for.

The language doesn't allow VDOT to consider any sort of transit alternative to widening the highway, even though there is a rapid transit option, the Orange Line, literally running down the middle. It already assumes that the only solution for I-66 is more lanes for cars. Besides, VDOT already studied widening I-66, and the results show that general purpose lanes are not effective, while HOV, managed toll lanes and express bus perform better.

Another bill, HB 1244 by Thomas Rust (R-Fairfax) would push forward on studies to build an Outer Beltway with new bridges over the Potomac outside the Beltway. This would stimulate more car-dependent sprawl on what is now rural land at the region's edge.

Maryland opposes the idea, in order to protect its rural land in Montgomery's Agricultural Reserve and Charles County in southern Maryland. It instead wants to add capacity, for transit or cars, on the American Legion Bridge between Potomac and McLean, and is widening the Route 301 Henry Nice Bridge south of Washington. Despite this, former Transportation Secretary Sean Connaughton initiated a study about potential new bridge locations. HB 1244 would make VDOT take the results of that study and recommend specific options.

Things are still very busy in Richmond. We are seeing the effects of local debates regarding Northern Virginia's transportation future reverberate at the state capitol just as hotly as they were contested back home. Bills rise and fall very quickly in the Virginia legislature, and we will keep you up to date on what is happening.

In Montgomery's transportation budget, wider streets are "pedestrian improvements"

As Montgomery County asks the state to spend more on transit within the county, its proposed budget pours money into sprawl-inducing highways instead, while calling road widenings near schools and Metro stations "pedestrian improvements."


Photo by thisisbossi on Flickr.

Last week, County Executive Ike Leggett sent his proposed $1 billion transportation budget for 2015-2020 to the County Council. It adds new money to build two $100 million highway segments, Goshen Road in Gaithersburg and the 8000-foot-long Montrose Parkway East near White Flint, and lets environmental studies for the even more expensive extension of Midcounty Highway continue.

But many transit, bike, and pedestrian projects have been delayed. The proposed BRT system will get a $10 million state planning grant, but no county funds. The $80 milllion south entrance to the Bethesda Metro station, which the County Council previously funded over objections from the Department of Transportation (MCDOT), was left alone.

Bicyclists get a speedup in construction for a bike path on Needwood Road, required under the terms of a state grant. But the money comes from slowing down work to complete the far more important Metropolitan Branch Trail. Bike projects on Bethesda Avenue, Frederick Road, and Seven Locks Road are delayed too.

MCDOT learned long ago that cars-first policies had to be disguised with lip service to transit and pedestrians, and this budget continues that tradition. While new roads are the first category in the current six-year budget, the new budget lists them after transit.

At first glance, the proposed transit and pedestrian budgets seem large, but this is a mirage. The numbers are inflated with items that belong elsewhere. The county calls a $70 million dollar garage for school buses and park maintenance vehicles a mass transit facility. Road widenings around new schools, previously classified as road projects, are listed as pedestrian improvements this year. Buried in the budget for a new Metro entrance at Medical Center is the cost of a turn lane a block away at Jones Bridge Road.

A telling example of MCDOT's attitude is how it justifies spending money on bike lanes in downtown Bethesda. The county planning board made us do it, agency officials say. The bike lanes must be built before development can proceed beyond a certain point. There's no thought that they might serve a transportation purpose.

In recent years the County Council has shown increasing willingness to challenge MCDOT's priorities. The council funded the $80 million south Bethesda Metro entrance in 2008 and repeatedly fended off requests to reverse that decision. Two years ago, it put off construction of Goshen Road and Montrose Parkway East and budgeted for the Capital Crescent Trail instead.

But MCDOT still clings to the traffic engineering doctrines of the 1950s. The one completely new big project in the budget is yet another upcounty highway, a segment of Observation Drive whose price tag is likely to wind up north of $50 million a mile. The Bethesda Metro entrance stands as the only major county-funded transit construction project.

The time has come to reject once and for all the discredited idea that wide highways are a cure for traffic congestion. The council should zero out all spending on upcounty highways and end the pernicious practice of forcing developers to widen roads. All of the county's scarce transportation dollars are needed to correct the expensive mistakes of the past with better transit and a street network that works well for pedestrians and cyclists, not just for drivers.

Adventure! Romance! Highway rest stops?

Am I crazy to actually like big highway rest stops?

Maryland's newest one is scheduled to open along I-95 next week, following a complete reconstruction. And somehow, despite the fact that it's merely a collection of fast food, dirty restrooms, and convenience marts, I think there will be just a touch of romance to the place.

Something about all waystations appeals to me. I know they're mundane and often uncomfortable places, but all of them, from airports to train depots to I-95 travel plazas, somehow tickle my sense of fantasy.

I think it's because waystations are the gathering places of travel, where humanity comes together and rests before setting off on adventure. Rest stops may not be exotic themselves, but they're where exotic stories begin. Somehow, with hundreds of traveling partners bustling around me, being in a waystation makes travel feel like a quest.

Or maybe I've just got an overactive imagination. Does anyone else feel this way?

Will Montgomery fund new transit, or build more roads?

Maryland's gas tax increase means it now has the most transportation funding in a generation. Will Montgomery County spend its share on transit to support its urban centers, or keep building highways?

Coupled with existing revenues, the new gas tax has made $15 billion available for transportation, a 52% increase from last year and the most transportation funding in a generation. This month, the County Council will send the state a list of their transportation priorities in order to receive some of that money. As in past years, there are a number of road projects on the list.

But the Planning Board, noting the high cost of new highways and efforts to direct future growth to urban centers, urged the council to choose transit instead. Transit isn't "the answer to every transportation problem," they write, but "where roadway widenings to solve perennial traffic congestion would significantly affect existing communities, natural resources and parkland, a more efficient solution is needed."

Funding would give county's transit plans teeth

Not all of the projects on the list are likely to receive funding. But if they were, the county's transit network could expand dramatically.

Some projects already have the support of county and state officials, including the Purple Line and Corridor Cities Transitway. Also included are funds for more 8-car trains on the Red Line, which will allow Metro to stop turning trains around at Silver Spring instead of running them to the end of the line at Glenmont.

There's also funding to build three of the county's proposed BRT lines along Georgia Avenue, Route 29, and Veirs Mill Road, as well as studying future lines on Rockville Pike and New Hampshire Avenue. A proposed HOV lane on I-270 could eventually support transit between White Flint and Tysons Corner. Planners also recommend funding new sidewalks and bike paths along Georgia Avenue between Forest Glen Road and 16th Street, which the State Highway Administration is currently studying, and a pedestrian underpass at the Forest Glen Metro station.

These projects would serve the county's existing urban centers, like Silver Spring and Bethesda, by giving people alternatives to driving. And they would support the development of future ones like White Oak, where County Executive Ike Leggett envisions a research and technology hub.

Planners say transit would better serve growth areas

But many of the road projects in the priorities list could undermine those efforts, whether by directing funding away from transit or by encouraging more people to drive there.

The priorities list includes three interchanges along Route 29 in East County, at Stewart Lane, Tech Road, and Greencastle Road, which have been in planning for decades and would cost $344 million. (Maryland has already set aside $7 million to design a fourth interchange at Fairland Road, estimated to cost $128 million to build.) Under the county's traffic tests, they have to be built before development in White Oak can happen.

County planners estimate that the three interchanges would cost the same to build as an 11-mile BRT line along the same corridor between downtown Silver Spring and Burtonsville. They say transit would not only better support the creation of a town center in White Oak, but give commuters from points north an alternative to driving, ultimately reducing local congestion.

"We believe that prioritizing the [Route 29] transit corridor improvements is the better choice," their report says.

Other road projects on the list include funds to build Montrose Parkway, a highway that would divide White Flint and Twinbrook. And there's a proposal to widen Norbeck Road between Georgia Avenue and Layhill Road and build an interchange at Georgia, even though the road runs parallel to the underused Intercounty Connector a half-mile away.

Maryland's new transportation funds present a rare opportunity to the state and Montgomery County, its economic engine. Some road improvements may be necessary and beneficial, especially in the county's suburban areas. But the county's urban centers are where most of its future growth will happen, and they need transit to thrive. We have to make the right choice now, because we may not get it again for a long time.
