VDOT is planning to start work on the Washington Boulevard Bridge - to be renamed the Freedman's Village Bridge - over Columbia Pike in the summer or fall of 2011 (tip ARLnow). They'll be awarding a design/build contract later this year and the project will wrap up in 2015. One part of the project is to widen Columbia Pike under the bridge, which will make more space for pedestrians and cyclists. The outside lanes will be 15 feet wide to accommodate cyclists and there will be a 10' shared-use path on one side and a 7' sidewalk on the other of Columbia Pike will run through the project area. The bridge will also be higher and will have a light well between the eastbound and westbound lanes.
Clearance under the bridge will be increased to 16'-8” to accommodate a future area streetcar. Columbia Pike will have 11-foot travel lanes (the outside lanes will be 15 feet to accommodate on-road bicyclists), a left-turn lane, and a raised median.
Back when Mrs.Washcycle was Ms. Not-Washcycle I used to bike through this underpass all the time, as she lived just off the Pike. Wide lanes and more light will be a welcome improvement.
