Part of the PWA grant included funds for the completion of John Marshall Park, at the intersection of 4th Street NW and Pennsylvania Avenue NW. Along with construction of the park, the city finally linked the two ends of Constitution Avenue by turning the western section slightly northward, and the eastern section slightly southward. The one-block section of Pennsylvania Avenue NW between 4th and 5th Streets was renamed Constitution Avenue (leaving Pennsylvania Avenue no longer contiguous). To control these two intersections, 10 traffic signals (some of the first to be installed in downtown D.C.) were placed at these intersections. The intersection opened on August 17, 1933.
