California has a broad variety of historic bridges, many reflecting the diverse and somtimes complicated terrain in the state. With a hit or miss commitment to historic bridge preservation, California has been home of some of the greatest examples of preservation in the country, while also choosing to demolish some of the most important bridges in the country. Preserved historic bridges in California are often good examples of how historic bridges can be seismically retrofitted to be safe, reliable crossings during earthquake events. HistoricBridges.org currently features coverage of bridges in northern California, specifically San Francisco and Sacramento and nearby counties. Coverage in these counties is not an exhaustive inventory, but in general the most significant historic bridges from these counties are all covered, and a representative sample of some of the less significant bridges is also usually included.
