Description
According to the 1917 Yearbook of the Monterey High School, "Because the school was surrounded by ravines and forest, the only way students could get into the school site was across the Larkin Street Bridge. The Larkin Street bridge was built exclusively to service the school, so they built the bridge before they built the school. The bridge was an engineering marvel of its time. The design is a suspension bridge, much like the Gold Gate bridge except encased in concrete. It remains one of the only bridges left in the country of this design.Facts

Larkin Street Bridge
This bridge of historic and engineering significance has been extensively reinforced in recent years. I found no data at bridge site to indicate the year of rehabilitation.

Craig here is a bridge for you to track down and photograph. It's another one of the John B. Leonard "Canticrete" bridges. Although I would love to photograph this structure, I have to admit that Monterey is a little outside my "within reason" geographic area.

Very peculiar looking rehab. It's looks almost as if they "applied" the old bridge over the top of a new structure. I would like to think there could have been a better way to keep the old structure intact, but perhaps this was the only alternative.
