Location

The Chain Bridge is a viaduct that crosses the Potomac River at Little Falls in Washington, D.C. The steel girder bridge carries close to 22,000 cars a day.^[2] It connects Washington, D.C. with affluent sections of Arlington and Fairfax counties in Virginia. On the Washington, D.C. side, the bridge connects with Canal Road. Left turns onto the Clara Barton Parkway from the Chain Bridge are prohibited, but the reverse is permitted. On the Northern Virginia side, the bridge connects with State Route 123 (Chain Bridge Road), which provides access to George Washington Memorial Parkway.

The Chain Bridge has three lanes (of which the center is reversible) and can be safely accessed by pedestrians and cyclists. The pedestrian sidewalk provides access to the Chesapeake and Ohio Canal towpath via a ramp. The bridge also carries water mains which provide Arlington County with water from the Washington Aqueduct.^{[citation needed]}
