The first highway bridge to cross San Francisco Bay was this bridge it was built in 1924 and completed and dedicated on January 15th 1927. It was 6.5 miles in length the state bought the bridge in 1951. In 1982 a new bridge was completed and declared worthless by the highway department. On September 24 1984 ironically the 72 anniversary of the dedication of the Dumberton Railway Bridge witch was the first railway bridge to cross San Francisco Bay. The first Highway bridge to do so was blasted away it cost 1 million dollars more to destroy than to build. 1500 feet of approach spans are left as Fishing piers on each side of the bay.

One more question - decades ago, I had heard that the original toll booth on the Dumbarton Bridge was on the draw span, not on the Coyote Hills as was later the case. Does anyone know more about this?

Photo #3 is of the original San Mateo - Hayward Bridge (1929- 1967), not that of the Dumbarton Bridge. the Dumbarton Bridge didn't have the rise in the truss and draw span section, and had 9 truss spans (6 on the west side of the draw span; the center or lift span; and two to the east of the east tower.) The San Mateo Bridge had a total of 5: 2 on each side of the lift towers, plus the center draw span.

Does anyone know when construction commenced on the original Dumbarton Bridge? The only information I'm able to find is just when it opened.
