Description 

The Carroll Overhead Bridge is composed of 26 spans of reinforced concrete T beams, with a curvilinear alignment and superelevation. Built in 1922-1923, it is the longest bridge of its type and age in the tri-county area of Alameda, Contra Costa and Santa Clara Counties. It is one the earliest curvilinear alignment concrete bridges in California. It is associated with the careers of two locally significant engineers: P.A. Haviland and George A. Posey. It has been determined eligible for inclusion in the National Register, meeting Criteria B and C at the local level. from HAER notes
