Notes
Survey number HAER CA-17
Building/structure dates: 1931 initial construction
Significance: San Roque Canyon Bridge is significant because of the commitment to concrete prevalent in California, the plate girder arch, as a type, is relatively rare. There are only two known in the State at this time, and since the other is a through arch span, San Roque Canyon Bridge is the only known one of its type in California.
