Around the District, four new sections of bike lanes and protected bikeways will replace existing driving lanes. These are part of four miles of planned new segments that will close gaps in the city's bike infrastructure.
They're focused on four major areas: the Metropolitan Branch Trail, the Klingle Trail, downtown, and closing gaps on Piney Branch Road, and near Catholic University. The projects are part of an amendment the District Department of Transportation (DDOT) is submitting to the Transportation Planning Board's long-term plan. DDOT is proposing to complete all of them this year, an undertaking that would cost $1.35 million. Here's a big-picture look at all of them:

Metropolitan Branch Trail
Three of the eight projects are related to the Metropolitan Branch Trail. One would cut Blair Rd NW from three lanes to two lanes from Peabody Street to Aspen Street (a total of 0.73 miles) to allow for that section of the trail to be added in.
Two other projects would, functionally if not explicitly, extend the trail south from Union Station to the National Mall. One would remove a lane from Louisiana Avenue from Columbus Circle to Constitution Avenue in order to add in a 0.42 mile long protected bikeway. The other would remove two lanes from the stretch of Constitution Avenue that runs from 1st to Pennsylvania Ave NW to add in 0.23 miles of protected bikeway.
Klingle Trail Connection
Another project would remove half the lanes on Klingle Road between the under-construction Klingle Trail at Porter Street and Adams Mill Road. This would allow for 0.31 miles of separated bike lanes on both sides of the street, which will help to connect Mount Pleasant and the new trail.

Closing bike lane gaps
The remaining three projects would close gaps in the current bike network. The first, in Edgewood, would remove a driving lane on 4th St NE between the existing bike lanes that end at Lincoln Road and the existing bike lanes at Harewood Road and add 0.27 miles of bike lane in their place.
The second would remove one of two driving lanes on the one-way section of Harewood Rd NW on the south side of the Soldier's Home Cemetery and replace it with a separated bike lane (I assume bi-directional). It would be 0.2 miles long between Rock Creek Church Road and North Capitol.
The last and smallest project, at 0.11 miles, would close a small gap in the bike lanes on Piney Branch Road NW between Georgia Ave and Underwood Street, again by removing a driving lane.
The Transportation Planning Board has opened a 30-day comment period on these changes. There are other new bike projects in the works around the region. The I-66 Multimodal Improvement Project includes bike and walking improvements, and a project to extend VRE to Haymarket will include three new stations with "bicycle access." The Crystal City Transit Way (BRT) promise bicycle and pedestrian facilities improvements, and the I-66 Outside the Beltway project notes that Bicycle and Pedestrian accommodations in the corridor are included as part of the Preferred Alternative.
