The Woodrow Wilson Memorial Bridge (also known as the Woodrow Wilson Bridge or the Wilson Bridge) is a bascule bridge that spans the Potomac River between the independent city of Alexandria, Virginia, and Oxon Hill in Prince George's County, Maryland, United States. The bridge is one of only a handful of drawbridges in the U.S. Interstate Highway System. It contained the only portion of the Interstate system owned and operated by the federal government, but was turned over to the Virginia and Maryland departments of transportation upon project completion.
