High Street Bridge
Posted August 10, 2011, by Nathan Holth (form3 [at] historicbridges [dot] org)

This bridge is quite unusual when considered in the greater context of fixed trunnion bascule bridges. The bridge is strikingly similar to the earliest fixed trunnion bascule bridges built in Chicago in the first decade of the 20th Century including external rack and through truss design, however this California example dates to 1939. Chicago engineers likely would have laughed their heads off at this bridge which they would have perceived as a ridiculously obsolete design. As early as 1914, Chicago's bascule bridge designs had evolved to eliminate the obstructive overhead bracing by use of pony and deck truss superstructures and the unsightly external rack was replaced with an internal rack design. It would be interesting to know why this older design was used here at High Street.
