Significance: The Winchester Bridge is the longest reinforced-concrete ribbed deck arch designed by Conde B. McCullough in the 1920s. It departs in aesthetic character from all his other deck arches in that it has a very strong Tudor and Gothic treatment of spandrel columns, curtain walls, and pedestrian lookouts. This long series of spans exemplifies McCullough's view that a reinforced-concrete arch should be favored in bridge design because of the "quiet, simple dignity of its lines."
