The bridges convey Interstate 695 across the Anacostia to its southern terminus at Interstate 295 and DC 295. The bridges also connect the neighborhood of Anacostia with the rest of the city of Washington.The first bridge at the site, constructed about 1800, played a role in the War of 1812. It burned in 1846, but was repaired. A second bridge was constructed in 1873, and replaced in 1907. A modern, four-lane bridge replaced the older bridge in 1965, and a second four-lane bridge added in 1969. In 2009, construction began on three spans (two carrying freeway traffic, one carrying local-only traffic) to replace the 1965 and 1969 bridges. The northbound bridge opened to traffic in December 2011 while the southbound bridge open to traffic in January 2012. The new bridges include new ramps and new interchanges with I-295 (the Anacostia Freeway). The local bridge opened to traffic in May 2012. Portions of all three bridges and their approaches remained under construction into 2013. Phase 1 of the project was completed ahead of schedule and within budget in July 2013. The local bridge was fully complete by September 2013. Phase 2 of the project, including the conversion of the Barney Circle Freeway into a boulevard, was completed in 2015.
