On July 13, just a month after the PWA was formed, the agency announced a $3 million grant to finish work on Columbia Island and other parts of the Arlington Memorial Bridge project. The CFA and NCPC met in November to decide how to proceed on Columbia Island, which had only one link to Virginia – and that led only to Arlington National Cemetery. On December 4, the agencies announced that PWA money would be used to construct bridges on the north and south ends of the island in anticipation of links with Lee Highway and a new highway the state of Virginia and Arlington County were discussing constructing in the south. (The southern bridge carrying the parkway became known as the Humpback Bridge because it had a slight rise in its center.) To connect to these bridges, completion of the roads on Columbia Island was also needed. These roads were staked out in January 1934, and the CFA and NCPC began discussing whether a new, large traffic circle should be added to the center of the island to replace the bottleneck that a simple cross-axis would be. The engineering and architectural design for the northern bridge was approved in October 1936.
