By April 1932, work was well under way on relocating the Pennsylvania Railroad tracks. The new, slightly shifted route had been graded, tracks laid, and the western end of Boundary Channel Bridge designed. While there were some delays in completing the railroad underpass, work was well advanced. The formal dedication of the Hemicycle, Memorial Avenue, and Boundary Channel Bridge occurred on April 9. Colonel Ulysses S. Grant III, executive director of the Arlington Memorial Bridge Commission and an officer in the Corps of Engineers, formally opened Memorial Avenue and the Boundary Channel Bridge. (Memorial Avenue was only wide and unpaved, but the Corps was working to have it widened to and have it paved by July 1.)
