Washington D.C. Road Map - AARoads

The capital of the United States, Washington, D.C., boasts a limited freeway system that supplements its spoke-like street system. Many of the originally planned freeways were not constructed, especially north of downtown. Interstate 95 was to have passed through the city center along current Interstate 395. Interstate 66 and 295 were to have also met the never built route, and never-built Interstate 266 was to act as a connector route between the two. Additionally, a southeast extension of the Southeast Freeway was never built (the "Barney Circle" Freeway). U.S. 1, 29, and 50 serve Washington. A deleted route, U.S. 240, was the original connector between the city and Frederick, Maryland, to the northwest. The District of Columbia only has one signed route, that of D.C. 295 along the northern portion of the Anacostia Freeway. Originally D.C. 4 existed along Pennsylvania Avenue, continuing the Maryland 4 numbering convention into the city.

District of Columbia Cancelled Freeways Map

District of Columbia
Theodore Roosevelt Memorial Bridge
Interstate 66 briefly enters the city of Washington before ending at U.S. 29 (Whitehurst Freeway west / K Street east). The freeway was planned to continue east along the North Leg of the Inner Loop freeway to a planned terminus at Interstate 95 where the current Interstate 395 ends. Additionally Interstate 266 was planned as a bypass route between the current Interstate 66 end and Cherrydale, Virginia. In 1977 all unconstructed segments of the D.C. Freeway network were cancelled2 and the freeway system exists as it does today. More information on Interstate 66 is available on its guide.

North Central Freeway
Plans also called for Interstate 70S (present Interstate 270 / Spur Interstate 270) to continue south of the Capital Beltway to an end with planned Interstate 95 at Fort Totten Park. Known as the North Central Freeway, this route along with other unconstructed routes at the time, was cancelled in 19772.

Capital Beltway
For the most part, Interstate 95 does not enter the District of Columbia; instead, it is routed along the Capital Beltway (Interstate 495). There is a very short portion of the Woodrow Wilson Bridge along the Capital Beltway as it crosses the Potomac River that is within the District of Columbia, but originally Interstate 95 was supposed to serve a much greater portion of the District. Interstate 95 was signed along what is now Interstate 395 within the District when the Interstate system was in its infancy. The route followed all of the existing Interstate 395 from the Capital Beltway to the Southwest Freeway and underneath the National Mall. The route was planned to continue northward through the city to meet the current Interstate 95 at the northern junction of Interstate 95/495 near College Park. A small stub of the planned Interstate 95 was built from the Capital Beltway southward. This segment now serves a metro station and park and ride line.

Whitehurst Freeway
Unconstructed Interstate 266 was to provide a bypass route for Interstate 66 travels between the Spout Run Parkway area of Fort CF Smith Park across the Potomac River to the Whitehurst Freeway and its interchange with K Street. The route was cancelled in 1972.1

District of Columbia
D.C. 295
Anacostia Freeway
Interstate 295 follows the Anacostia Freeway northward from the Capital Beltway to the 11th Street Bridge and its current end at unsigned Interstate 695 (Southeast Freeway). Interstate 695 continues the drive westward to downtown Washington for commuters emanating from Maryland via Interstate 295. The designation will be changing in the near future as construction is planned at the 11th Street Bridge and Anacostia Freeway interchange to include full movements to the D.C. 295 freeway. Upon completion, Interstate 695 will be signed and overtake Interstate 295 across the 11th Street Bridge.

Historically, Interstate 295 is part of the East Leg Freeway of the Washington Inner Loop. Unconstructed from Pennsylvania Avenue northward, Interstate 295 would have followed the Anacostia River to Lake Kingman and a northwestern turn to an interchange with Interstate 95 and U.S. 50 at Eckington.

District of Columbia
Southwest Freeway
Interstate 395 replaced Interstate 95 along the Henry Shirley Memorial Highway from Springfield northeast to Washington, DC and the Southeast and Center Leg Freeways within the District. The Shirley Highway originally opened as Virginia 350.

Capital Beltway
Although only touching the extreme southern point of the district, the Capital Beltway plays a pivotal role in the traffic scheme for metropolitan Washington. The zero milepost for the highway exists at the Woodrow Wilson Bridge. That bridge represents one of the few Interstate drawbridges in the country. Overall the bridge carries 12 lanes, while the beltway varies between six and eight overall. The interchange with Interstate 95 and 395 at Springfield underwent a transformation from an outdated ground level one to that of a high level stack. The new interchange includes high speed ramps that funnel traffic to and from the Capital Beltway. The beltway corridor has been engulfed with development, and overall the highway reflects this with high traffic counts.

Interstate 95 was moved to the Capital Beltway when it was determined that it would not be completed between central Washington and the beltway. At that point, Interstate 395 was christened, with Interstate 95 taking over the Interstate 495 designation on the eastern side of the beltway. Interstate 495 was later cosigned with the eastern half to provide continuity with the western half.

District of Columbia
Southeast Freeway
Interstate 695 exists as an unsigned route linking the Southeast Freeway with Interstate 395 (Southwest Freeway) and Interstate 295 (11th Street Bridge) and as a spur eastward to Pennsylvania Avenue. Planned as part of the South Leg Freeway, Interstate 695 was to connect Interstate 66 at the Constitution Avenue interchange with Interstate 295 at the 11th Street Bridge. Part of this alignment uses the Southwest Freeway of Interstate 395 (planned then as Interstate 95). The segment by the Lincoln Memorial was cancelled by 1977.2

New plans underway involve upgrading the current 11th Street Bridge interchange with the Anacostia Freeway (D.C. 295) to include full movements in all directions. This interchange upgrade coincides with a planned rerouting of Interstate 695 southeast across the Anacostia River to end at Interstate 295. Interstate 295 will seamlessly transition into D.C. 295 instead of spurring northwest. Future plans may see the Interstate 295 designation extended northeastward over the Anacostia Freeway. Meanwhile to the north, the Interstate 695 spur east to Pennsylvania Avenue will be removed.

U.S. Highways

Three U.S. routes pass through the district. U.S. 1, which cosigns with U.S. 50 in central Washington, provides a main route to northeastern Washington from government complex area. The highway follows Rhode Island as it exits the city towards College Park, Maryland. U.S. 1 Alternate follows U.S. 50 (New York Avenue) east from U.S. 1 to Bladensburg Road north to Cottage City and Edmonston, Maryland.

U.S. 50 enters the district on a freeway that connects Washington with Annapolis and the Chesapeake Bay Bridge in Maryland. The route links Interstate 395 with the aforementioned freeway along New York Avenue. This street facilitates six lanes of travel with a 35 mile-per-hour speed limit. The highway cosigns with U.S. 1 along Sixth and Ninth Street into central Washington. The highway crosses the Potomac River along the Interstate 66 Theodore Roosevelt Memorial Bridge into Virginia.

U.S. 50 enters Washington from Cheverly, Maryland as a freeway (John Hanson Highway) and travels New York Avenue west to a merge with U.S. 1 Alternate (Bladensburg Road). The freeway was originally intended to end at unconstructed Interstate 95 and 295 (East Leg Freeway) at Eckington.

The last existing U.S. highway routed within the city is U.S. 29. The highway enters the city from Arlington, Virginia along the Francis Scott Key Bridge. Upon crossing into Washington, U.S. 29 intersects the eastern terminus of Interstate 66 via the Whitehurst Freeway. U.S. 29 heads north from K Street north of the government district to Silver Spring and Wheaton in Maryland.

There were two other U.S. routes that served the city: U.S. 211 and 240. U.S. 211 paralleled U.S. 29 and terminated near downtown; the duplication was eliminated. U.S. 240 was terminated with the completion and designation of Interstate 270. U.S. 240 followed Maryland 355 (Rockville Pike) from Rockville, Maryland into Washington via Wisconsin Avenue. The route spanned the Potomac River via the Arlington Memorial Bridge to an end in Virginia.
