Designated Virginia State Route 350, the Henry G. Shirley Memorial Highway initially opened at Arlington in 1944. The freeway ran between U.S. 1 at Woodbridge and the 14th Street Bridge into D.C. by 1952. Upgrades to Interstate standards followed between the mid-1960s and 1975, when I-95 was signed in place of SR 350.2
With cancellation of the Center Leg Freeway north to unconstructed sections of both I-66 and I-295 (East Leg Freeway), Interstate 95 was rerouted onto the Capital Beltway in 1977
The Federal Highway Administration (FHWA) approved a request to withdraw two segments of the Interstate Highway System and transit project substitutions in Washington, DC on October 3, 1975. This included all of I-70S within the District of Columbia and I-95 from I-295 in Washington northeast to I-495 (Capital Beltway) in Prince George’s County, Maryland. State transportation agencies for Maryland and Virginia came into agree with officials from D.C. to reroute I-95 along the Capital Beltway. Additional renumbering involved redesignating the Shirley Highway in Northern Virginia and the Southwest Freeway northward to the junction with I-295 in Washington as Interstate 395. The American Association of State Highway and Transportation Officials (AASHTO) approved all of these actions on November 15, 1975, though the designation for I-395 was listed as pending.
The FHWA suggested Interstate 895 as the designation in a letter to AASHTO on November 11, 1975:
We agree with the proposal by the District of Columbia and Virginia to assign a three-digit number to the presently numbered segment of I-95 from an intersection with I-495 in Virginia to an intersection with I-295 in the District of Columbia. But, since the route is not a spur, the request to number the route as I-395 is not compatible with existing route numbering policies. Perhaps another number such as I-895 should be considered.
AASHTO followed up with the Virginia Department of Transportation (VDOT) and the District of Columbia Department of Transportation (DDOT) on December 2, 1975 to review and advise if I-895 was acceptable in place of I-395. DDOT responded by January 13, 1976, indicating that they previously considered I-895 as an alternative, but elected to request I-395 for several reasons:
The route is a spur route; the present terminus is with the city’s arterial street system.
Public sentiment and policy does not offer assurance that the route will be extended to connect with I-295 nor does it assure that I-295, as now designated, will be constructed to intersect with proposed I-395.
The I-395 numbering will tell the motorist to expect a route end; an even digit prefix suggest bypass routing and return to a main line via freeway.
Since it is our best guess that extension of this facility will not terminate in a connection with another I-95 segment, it is our judgment that the route numbering change to I-395 will more likely result in one re-signing of the routes involved thereby eliminating the costs and confusion of an additional route number change.
Per discussion with AASHTO, reservations from Virginia Governor Norbert T. Tiemann for the renumbering of I-95 to I-395 were withdrawn and an application for the change was placed for the Route Numbering Committee Meeting on July 12, 1976. With concurrence from the FHWA, the I-395 numbering was subsequently approved on November 13, 1976.
A District of Columbia proposal in 1984 outlined numbering changes for both the Center Leg and Southeast Freeways. Realignment for Interstate 395 would replace both unsigned routes of I-695 and I-295 along the Southeast Freeway east to Capitol Street. Interstate 195 would be established along the Center Leg Freeway north from the Southwest Freeway to U.S. 50 (New York Avenue). The renumbering request to AASHTO was approved by the Route Numbering Committee on May 23, 1984. However the changes were not implemented on area roads.
The Interstate 195 proposal took place during work to complete the Center Leg Freeway north of Massachusetts Avenue. Several General Drafting maps and the Rand McNally 1985 Northern American Road Atlas showed the I-195/395 change.
Completion of the northern segment of the Center Leg Freeway was delayed from 1978 to 1984 due to a lack of funding. Work resumed at that time, and the northbound lanes opened to traffic in December 1986, followed by the southbound lanes in February 1987.3
The Virginia Department of Transportation (VDOT) Springfield Interchange project rebuilt the substandard cloverleaf interchange joining I-95, I-395 (Shirley Highway) and the Capital Beltway (I-95/495) into a multi level systems interchange. Work was completed in July 2007 after eight years of construction. HOV connections were added later.
Prior to their conversion to tolled Express lanes, the HOV-3 lanes along Interstate 395 required vehicles to have three occupants during morning (6:00 a.m. – 9:00 a.m.) and afternoon (3:30 p.m. – 6:00 p.m.) commuting hours. Motorcycles, alternative fuel vehicles and emergency vehicles were exempt from the HOV restrictions.4,5 The lanes were open to all motorists during non peak hours.
