Two new cycletracks will open in DC this spring, on M Street NW and 1st Street NE. Their designs are a step up from previous DC cycletracks, since they each include spots — though on M, a very brief spot — where a full concrete curb separates bikes from cars.

The 1st Street NE cycletrack connects the Metropolitan Branch Trail to Union Station and downtown DC. DDOT installed its curb last week, from K Street to M Street. Crews are still working on striping and signals, but the project is close to opening.

The M Street cycletrack is longer than 1st Street’s overall, but the portion with a curb is shorter. It’s less than one block, where the cycletrack briefly curves onto Rhode Island Avenue in order to approach Connecticut Avenue more safely. Officials say the M Street cycletrack is a week or two from opening.

Typically DDOT uses plastic bollards instead of curbs. The bollards are less expensive, easier to install, and can be removed occasionally to perform street maintenance. But they’re less attractive and less significant as a physical barrier, compared to a curb.
