Build an Arlington Memorial Bridge for All

President Hoover inspects the then-new Arlington Memorial Bridge in this newsreel footage from 1932. Video from British Pathe.

The Arlington Memorial Bridge, completed in 1932, represents a physical link between the U.S.’ acknowledged north and south—and connects the Lincoln Memorial and National Mall to Arlington National Cemetery. The video above is a newsreel from the bridge’s 1932 opening with President Herbert Hoover. Today, millions of visitors and commuters cross Arlington Memorial Bridge annually by foot, bike, and car. The National Park Service is currently planning a rehabilitation of the bridge.

The major focus of the rehabilitation are the bascule spans. “Bascule” is the technical term for the type of center drawbridge spans on the bridge, which are deteriorating rapidly and require a complete overhaul. Rehabilitating the bascules will maintain an important element in our nation’s history and in our modern transportation infrastructure. The National Park Service is seeking input from the public about the bridge rehab through an Environmental Assessment process. But the only alternatives presented are very technical and specific types of engineering solutions to replace or rehabilitate the span. Should NPS replace with bascule spans with “concrete box girders,” “steel plate girders,” or “concrete arches”? Or should they just rehab the current spans?

WABA is not an engineering firm. And we don’t expect the public to be able to tell NPS just which type of girder or span is the best to last another 70-plus years. Rather, we’d like to discuss if we can build a multi-modal bridge for the future.

The bridge is 90 feet wide with six car travel lanes and two 15-foot sidewalks. Pedestrians and bicyclists share the sidewalks. During busy tourist seasons, the sidewalks are full of visitors walking between the National Mall and Arlington National Cemetery. Sidewalk congestion is complicated by bicyclists and pedestrians sharing limited space.  The speed limit for vehicles on the bridge is 30 miles per hour, but drivers often significantly exceed the legal limit. Commercial vehicles are prohibited from the bridge because it falls within the George Washington Memorial Parkway.


During construction, there will be either a full or partial closure of the bridge. Planning staff are considering the impacts on regional traffic of different traffic closure scenarios. With a complete closure, construction can be expedited and potentially less expensive. A partial closures requires phasing construction to allow some traffic to still use the bridge. After an initial study on regional traffic patterns, engineers determined a closure of one of the three lanes in each direction would only minimally impact traffic on other bridges that cross the Potomac River.

Bicycle and pedestrian travel is increasing regionally and we should plan for it. Locally, the National Mall is planning in the future to build a visitor center at the Vietnam War Memorial. There is expected to be an increase in travel between the Vietnam War Memorial and Arlington National Cemetery. The distance between the two locations is a short walk or ride and proximate to Capital Bikeshare.

If there is a minimal impact of closing a single lane of car traffic in each direction on the bridge during reconstruction, it should be repurposed entirely as a single travel lane for bicycle traffic. Below are images of the current street configuration of the bridge and a proposed new allocation of space. This road diet does not change the historic design of the sidewalk, curbs, or roadway space. The protected bike lanes could be achieved by painting a buffer between the bike lanes and car lanes, or with decorative brick pavers or colored concrete.


Access for pedestrians and bicyclists to the Mount Vernon Trail from the bridge requires crossing the GW Parkway’s high-speed traffic at grade. This has been the scene of many crashes over the past few years. The Park Service has made some improvements to the circle by modifying sightlines, moving crosswalks, piloting rapid flashing beacons at crosswalks, and installing better signage, among other changes. NPS staffers are pursuing safe and separated trail crossings across the GW Parkway to improve access to the bridge. They will begin an environmental assessment of the Memorial Circle in 2014.

The bridge will continue to connect many historically and culturally significant parks, places, and memorials. The inclusion of protected bicycle lanes in the Arlington Memorial Bridge EA could dovetail nicely into the Memorial Circle EA, resulting in a significantly improved connection between the District of Columbia and Virginia for residents and visitors to our Nation’s Capital.

The comment period ends next Monday, Dec. 2. Please take a moment and as the National Park Service to rebuild the Arlington Memorial Bridge with dedicated space for bicycles, pedestrians and cars.
