Today in Interstate History

April 20, 1957

The Bureau of Public Roads announced that, three years after the project had been authorized by Congress, engineering planning on the Washington, D.C.-area Woodrow Wilson Bridge would finally start. The bridge, which carries I-95 and I-495 over the Potomac River between Alexandria, Virginia, and Prince George's County, Maryland, ultimately opened to traffic in 1961. The structure is one of just a small number of drawbridges on the Interstate System.
