Interstate 395 (Southwest Freeway) east of the 7th Street SW overpass. I-395 turns north along the Center Leg Freeway at the adjacent exchange with I-695 (Southeast Freeway). 08/01/05

Interstate 395 replaced the original route of I-95 north from Springfield, Virginia to Washington, DC. Designated in 1977 when plans for I-95 north of the Center Leg Freeway were cancelled, I-395 follows all of the Southwest Freeway in Washington. I-95 shifted east to overtake I-495 along the Capital Beltway in 1977. I-395 turns north along the completed portion of the Center Leg Freeway. However changes to be implemented will renumber the Center Leg Freeway as Interstate 195 and redirect I-395 over what is I-695 along the Southeast Freeway and 11th Street Bridge to I-295/D.C. 295 (Anacostia freeway). These changes were approved by the American Association of State Highway and Transportation Officials (AASHTO) on November 20, 2020.

Interstate 395 serves the Pentagon in Arlington, Virginia, while passing underneath the U.S. Capitol area and National Mall in central Washington. The highway ends unceremoniously at U.S. 50 (New York Avenue) eastbound.

Interstate 395 D.C. Guides

Interstate 395 spans the Potomac River amid three bridges. The 14th Street Bridge consists of the 1950-built Rochambeau Bridge with four lanes northbound and the southbound four-lane George Mason Memorial Bridge constructed in 1962. A third span, opened in 1972, parallels the south side of the George Mason Bridge with four HOV lanes.1 Lanes on these bridges come together at the Washington Channel Bridge leading east onto the Southwest Freeway.

The Southwest Freeway fully opened to traffic on August 26, 1963.1 It included stubs for the Southeast Freeway (I-695) and the Center Leg Freeway. Construction commenced on the northerly component of future I-395 in 1966, but delays pushed back the opening north to E Street NW until November 5, 1973. This portion includes 3,500 foot long cut and cover tunnels.

Extension of the Center Leg Freeway north to New York Avenue NW (U.S. 50) includes a 1,250 foot long tunnel from Massachusetts Avenue to K Street NW. Work started on this portion in 1975, but like the southern segment, delays ensued in 1978. Funding to complete the Center Leg Freeway was finally obtained by 1984. Costing $84 million, the last section opened on February 6, 1987.2
