The new bridge will cross just downstream (right) from the railroad bridge in the photo above. The City of Benicia is in the foreground in the picture, with part of the industrial area of Martinez just across the Strait, and in the distance the Clayton and Ygnacio Valleys where. the Cities of Con- cord, Pleasant Hill, and Walnut Creek are growing together into one great resi- dential city at the foot of Mount Diablo. In the upper left of the photo are more of the industrial developments which are graduaBly taking up the sites along the waterfront between Martinez and Stoek- ton.
