Description 

The bridge was built by the Park Boulevard Company, owned by Oakland real estate developers Walter and Harry Leimert, to give easy access via a road and street car line serving their real estate developments on the south side of deep Diamond Canyon, through which Sausal Creek flows, and connect with their developments along Park Boulevard on the north side of the canyon. Park Boulevard connected these developments with downtown Oakland. The bridge has been declared Oakland Landmark number 40. The designer was the talented engineer, George Posey, who designed the Posey Tube connecting Oakland and the Island of Alameda under the Oakland Estuary.

Today tall trees and other shrubs growing in Diamond Canyon almost completely obscure the bridge.
