suspension bridge

On August 11, 1930, the War Department issued a final permit for the construction of a suspension bridge across the Golden Gate Strait with a 4,200-foot main span, a vertical clearance of 220-feet at midspan, and a 210-foot clearance at the sidespans. Here, with the towers erected and main span in place, construction of the roadway continues.
