16th & U getting contraflow lanes, bike boxes
DDOT's long-term plans for U Street include major bicycle improvements at the corner of 16th and U. While a full reconstruction is not scheduled soon, the agency isn't waiting to implement some improvements for cyclists at this location.
The changes, which are being studied through FHWA's experimentation process, include contraflow bike lanes on New Hampshire and bike boxes on 16th Street.
Cyclists coming from New Hampshire will be detected by an induction loop in the roadbed and given a short signal phase that will stop other traffic and allow riders to cross 16th to the bike box. In short, cyclists who wait will be rewarded with a protected crossing of 16th Street.
Although the diagram indicates the lanes will be striped green, this will not be the case at first. The lanes may be striped with color at a later date. The first signs of project implementation are now sprouting at the intersection, including new signals and induction loops.

Seriously- induction loops, contraflow bike lanes that switch sides of NH avenue, hopping between bike boxes... the amount of complexity here seems excessive. I will be astonished if everyone can actually figure out where they're supposed to be, and the electronics all work right, to any kind of efficient and safe end result.

The City of Berkeley has bike induction loops along several of their bike boulevards that work really well. A few of them are about 20 feet back from the intersection, so the signal turns green before you even get there, meaning you don't have to stop. Pretty cool.

If DDOT wants to put some paint down in this intersection they should do dotted lane guides on the south half of U, the greatest danger to cyclists here is cars headed east on U who don't go into the correct lane on the other side of the intersection because of the misalignment between the curbs east and west of 16th on the south side.

I've noticed an increasing number of cyclists over the last several years who just 'breeze on through' the intersection of New Hampshire and S Streets while traveling north or south on New Hampshire. Some 4 years ago stop signs were added to New Hampshire at that intersection because the general increase in traffic (car traffic) on New Hampshire over the years meant that it had become unsafe for traffic on S Street to enter that intersection. DDOT did a great job in recognizing this problem and solving it. But like I said, the bike traffic breezing through on New Hampshire does not seem to be respecting these stop signs that are critical for the safety for all. I have no doubt that the cyclists will obey the new bike traffic signals up at New Hampshire and U. But the increased bike traffic those signals will bring to New Hampshire and S will create a real problem there unless the cyclists also start stopping at those stop signs too. Over all, I think this new infrastructure for cyclists is good because with it will come the requirement to act responsibly. I.e., like European cyclists do, our Washington cyclists will need to start obeying the rules of the road. And that includes stopping at ALL stop signs.

But that was just one part of it. This system seems to have a lot of moving parts. Intersections that work well and are safe are simple. If road users face unfamiliar, complex constructs, they can become confused, leading to errors. This seems like it is anything but simple.
@Scott F - what Duke of Admo may be getting at is the necessity of handling this particular intersection.
You make it sound like New Hampshire Avenue at 16th & U is part of some major diagonal route. However, it is not. It ends two block away at the bottom of Malcolm X Park and doesn't pick up again until more than a mile away near the Petworth metro.
So, for a cyclist traveling downtown on New Hampshire Avenue from the U street area, there's little benefit to "picking up" New Hampshire there or one block northeast, rather than a block further southwest.
Given that there's a separated bike lane on 15th, wouldn't a much more sensible, safe route for someone going south be to use 15th Street, then cut back on S Street, and entirely avoid this little mess?
This would only add 1.5 blocks to the trip; avoid a complex interchange; and keep the cyclist on a route with a dedicated bike path.
I am not sure that it makes sense to try to create bike-only infrastructure at every single intersection, when fully-built-out alternatives exist a block away. Bicycles are always free to simply use the same travel lanes as cars, of course.
In this case, we are creating something that seems very complicated in order to let bikes go where cars can't go since NH Avenue is one way. I am dubious that it is going to be a net positive for either bikes or cars.

There are bike lanes on V and W. Those two blocks of NH are important because they connect the rest of NH to those bike lanes. The contraflow lane on the south side will allow bikers to continue on NH going north all the way to V or W, and the one on the north side will allow people to come off V or W onto NH and ride on the one-way part of the street.
Seriously, this isn't that complicated, nor is it bike-only infrastructure on "every intersection."

Trust me on this, I've ridden through this intersection every day for 3 years.

My problem with the principle of this is that it adds a lot of complexity to an already messed-up intersection. I really doubt it's going to be safer, especially when you consider the typical cyclist's lack of interest in following signals.
