Sidewalks are being built on the south side of 51st Street between Mingo Road and the Mingo Valley Expressway, as shown looking west from the southbound expressway bridge. The expressway opened to 71st Street in November 1989, at which time the left-turn signal was installed on a pole in the median. The westbound mast arm, which previously had a spot for the left-turn signal, was shortened. The street should open this summer. Photograph taken May 25, 1991.
