is the clark memorial bridge a toll bridge
George Rogers Clark Memorial Bridge It was designed by Ralph Modjeski and Frank Masters with architectural details handled by Paul Philippe Cret of Philadelphia, and construction began in June 1928 by the American Bridge Company of Pittsburgh at a cost of $4.7 million. President Herbert Hoover dedicated the bridge.[2] It was opened to the public on October 31, 1929 as the Louisville Municipal Bridge and operated as a toll bridge. The toll was 35 cents until December 31, 1936, when it became a quarter. The last of the bonds that financed the construction were redeemed in 1946, and the tolls were removed.[3]
San Francisco–Oakland Bay Bridge Freeway ramps next to the tunnel provide access to Yerba Buena Island and Treasure Island. Because the toll plaza is on the Oakland side, the western span is a de facto non-tolled bridge; traffic between the island and the main part of San Francisco can freely cross back and forth. Those who only travel from Oakland to Yerba Buena Island, and not the entire length to the main part of San Francisco, must pay the full toll.
