This bridge is historically significant as an early surviving example of a concrete arch bridge. It also has a few unusual details. It has a cantilevered sidewalk, but the cantilevers are riveted metal and not concrete as one might expect. The sidewalk has a wooden deck, also unusual for a concrete bridge. The railings also exhibit some metal details with their design consisting of a solid concrete parapet base topped with gas pipe.
Under the bridge there are remains of caissons, the "Lally column" style consisting of concrete fill within a large riveted steel tube. It is assumed these supported the previous bridge at this location. What is interesting is that this type of substructure did not become common until at least the 1890s. This would suggest that the previous bridge may have not had a long service life.
This bridge was essentially bypassed by a new modern bridge to the north. However, the bridge remains in use as an access for E & J Gallo Winery, which is located east of the bridge.
