Unofficially, this interchange is also referred to The Mixing Bowl. This moniker causes confusion, because the intersection of I-395, Washington Boulevard, and Columbia Pike several miles north was historically known by that name, and continues to be recognized by the Virginia Department of Transportation as such.
I-395 contains a reversible, barrier-separated HOV facility, with its own entrances and exits, provided as a third roadway of Interstates 395 and 95 between Washington, D.C., and State Route 234 in Prince William County, Virginia. During rush hour, the HOV facility operates in the direction of rush-hour traffic and is restricted to vehicles containing three or more passengers. At other times, the facility is either open to all traffic in one direction or closed to all traffic.
In Virginia, motorcycles, alternative fuel cars, and federal law enforcement vehicles are permitted to use HOV lanes, even if carrying only one occupant. The law allowing hybrid vehicles to use HOV facilities was scheduled to expire on July 1, 2007, but in March 2007 the existing rules were extended until July 1, 2008. Special restrictions now apply to the I-395/I-95 corridor: hybrids bought and registered before July 1, 2006 may continue using the I-395 HOV facility with only one occupant, while hybrids purchased after June 30, 2006 are subject to standard restrictions in the corridor. (Single-occupant hybrids are still permitted in all other HOV lanes in Northern Virginia, such as those on I-66 and the Dulles Toll Road. )
The facility was initially constructed with a single lane as the first busway in the United States before being expanded and converted to HOV use.
The portion of Interstate 395 between The Pentagon in Arlington, Virginia and the interchange with Interstate 95 and the Capital Beltway in Springfield was originally part of the Henry G. Shirley Memorial Highway, named for a Virginia Highway Commissioner, who died on July 16, 1941, just a few weeks after approving work on the new expressway. Originally State Route 350, the full-length of the Shirley Highway was opened on September 6, 1949 from south of the Pentagon to Woodbridge, Virginia along what is now the Interstate 95 corridor. The Shirley Highway featured the nation's first reversible bus lanes, a precursor to today's HOV lanes.
