because of the cancellation of the originally-proposed section of i-95 from new york avenue in the district of columbia, northward into prince george's county to interstate 495, the capital beltway, the i-95 designation was rerouted onto the eastern half of the beltway. the remaining portion of the shirley highway north of springfield was redesignated interstate 395, and continues into d.c. to its end at u.s. route 50 (new york avenue).
