Rhode Island Avenue is a diagonal avenue in the Northwest and Northeast quadrants of Washington, D.C. and the capital's inner suburbs in Prince George's County, Maryland. Paralleling New York Avenue, Rhode Island Avenue was one of the original streets in Pierre L'Enfant's plan for the capital. Today it is a major commuter route, carrying U.S. Route 1 traffic into the city from Prince George's County.The western terminus of Rhode Island Avenue is in downtown Washington, at an intersection with Connecticut Avenue and M Street, N.W. The Cathedral of St. Matthew the Apostle is on Rhode Island Avenue, just east of that intersection. Just east of the cathedral, at Scott Circle, Rhode Island Avenue intersects Massachusetts Avenue and 16th Street, N.W. N Street stops short of meeting the circle from either direction, but is instead connected to Rhode Island and Massachusetts avenues through two short streets, Corregidor Street and Bataan Street. From Scott Circle, Rhode Island Avenue continues eastward to the Logan Circle neighborhood. At the traffic circle of the same name, Rhode Island Avenue intersects Vermont Avenue, 13th Street, and P Street, N.W.
