Shirlington Circle

From Wikipedia, the free encyclopedia

Shirlington Circle is a traffic circle interchange connecting I-395 (Shirley Highway) with several surface roads in the Shirlington area of the Washington, D.C. suburb of Arlington County in the United States. The circle resembles roundabout interchanges common in the United Kingdom and Ireland but rare in the US.

The circle includes multiple access points including ramps (slip roads) to and from I-395 (Exit 6) both north and southbound as well as a reversible direction ramp that provides access to and from the reversible high-occupancy vehicle (HOV) lanes that run in the center of I-395. Surface streets in the area that intersect with the circle include Shirlington Road, Quaker Lane (State Route 402), Gunston Road, and 28th Street South. Traffic generally follows roundabout rules, i.e, traffic inside the circle has the right-of-way and traffic entering the circle must yield. However there are also traffic lights and stop signs regulating traffic flow and the I-395 off-ramps enter the circle from the interior of the circle requiring a left merge into the traffic circle.
