California has a wealth of iconic landmarks that let residents and visitors alike know they are in the Golden State. Many of these landmarks are the state's historic bridges and tunnels that range from the spectacular Bay Area and elegant Los Angeles River bridges, to the simple and aesthetic bridges of the Central and North Coast, and the rustic bridges in rural areas throughout the state. The Caltrans Division of Environmental Analysis and cultural resources specialists in the 12 district offices work closely with Caltrans engineers and maintenance staff, as well as local governments and historic preservation groups, to preserve and protect the historic bridges and tunnels of the Golden State. This webpage is a cooperative effort among the Division of Environmental Analysis, the Caltrans Transportation Library and History Center, and the Division of Engineering Services to provide information to Caltrans staff, other governmental entities, consultants, engineers, cultural resources specialists, and anyone who is interested in these resources. It serves as a portal to information about these resources, including historic contexts for historic bridge types, information on individual historic bridges, and technical guidance. If you have questions or comments about historic bridges or the historic bridge inventory, please contact the Cultural Studies Office.
