Street Bridge at the time. The Kenilworth Interchange, between the Expressway, US-50 and the Parkway started work in 1956 and ended at the same time as the Expressway. Initial construction of the Anacostia Freeway began in the summer of 1957 with the East Capitol Street overpass over Kenilworth Avenue and was completed in 1964. The final part of the project, the connecting ramps to the 11th Street Bridges opened the following year. The Expressway between Benning Road and the District Line was built on the right of way of the former Benning streetcar line, which is why parts of it are narrow with short entrances and exits. Until May 1, 1949, streetcar routes 10 and 12 operated from downtown to Deane Avenue. Route 10 continued to Kenilworth, just inside the District Line. Route 12 turned off and ran to Seat Pleasant. That right of way was later paved and it is now called Nannie Helen Burroughs Avenue. The southern portion of Anacostia freeway, I-295, officially ends on a ramp to the 11th Street Bridges, though it originally referred to everything south to Oxon Cove. For years the northern portion between there and the District Line was often referred to as Route 295 even though it bore no such markings. It was not long after parts of the Baltimore-Washington Parkway in Maryland were numbered MD 295 in the 1980s that the District of Columbia numbered its portion as DC 295. Exit list Exit numbers were added in 2014 as part of the 11th Street Bridges reconstruction. The entire route is in Washington, D.C. See also List of numbered highways in Washington, D.C.
