Southern California is not well known for its waterways. While many are dry most of the year, they still can create hazards during wet periods. These wet periods create floods which warrant the construction of great bridges. Some of these bridges have stood the test of time, flooding, and earthquakes. The structures that have survived will be covered on this site, broken down by the county they are located in. It will take some time to compile the information and photos for this site, so please be patient.
