the East Capitol Street overpass over Kenilworth Avenue, and I-295 opened in pieces; the final section of the route, the from Bolling AFB and NSF Anacostia to the Pennsylvania Avenue interchange, opened on August 7, 1964. The final part of the project, the connecting ramps to the 11th Street Bridges, opened the following year. In 1990, a section of connecting ramps was built to directly connect I-295 to MD 210 in order to remove the significant traffic flow between the two routes from the segment of the beltway between both interchanges. These ramps are not considered part of the mainline of I-295. East Leg Under the 1971 DC freeway plans, I-295 would have turned east at the northern end of the 11th Street Bridges and followed the Southeast Freeway as far as East Capitol Street, where it would turn north and follow the East Leg of the Inner Loop freeway. The East Leg, six lanes wide, would have curved around the far eastern edge of the downtown area, passing beneath Mt. Olivet Road in a half-mile () tunnel, before terminating at I-66 and I-95 north of Washington Union Station, providing access to the North Leg Freeway, the North Central Freeway, and the New York Avenue Industrial Freeway. Reconstruction of the southern terminus As part of the larger Woodrow Wilson Bridge reconstruction project, the southern terminus of I-295 has been significantly rebuilt. Several new connections have been constructed to link the beltway, MD 210, and I-295 with the new National Harbor site on the shore of the Potomac River in Prince George's County, Maryland. One feature of the interchange reconstruction is that accommodations were made for future ramps to proposed high-occupancy vehicle lanes (HOV) on the beltway. This project was completed in stages, starting in 2008 and ending in 2011. Reconstruction of the northern terminus The cancelation of both the remainder of the Southeast Freeway and then the Barney Circle Freeway left no through connections between the 11th Street Bridges and DC 295 north, leading to severe congestion and major traffic routing problems. These missing movements were included when the northern terminus was reconstructed, allowing direct freeway-grade access to and from DC 295 at the 11th Street Bridges as well as providing a through grade-separated north–south route within DC. Project construction began in 2011 and the ramps opened in 2012. I-295 now terminates at the interchange with the 11th Street Bridges.
