This bridge is an uncommon example of a pin-connected Parker truss, although multiple examples survive on the Russian River. The bridge also is noted for its multi-span configuration, with three main spans. A series of concrete t-beam spans provide an approach to the main spans. The bridge truss configuration is unusual in that with the two center panels of the truss, the diagonal members pass through two panels instead of just one which is the case with the other panels on the truss. The center panels make the bridge look like a Pennsylvania truss, although the other panels do not display this design, which is why the bridge is being classified as a Parker and not a Pennsylvania truss. The truss retains lattice railings. The good news with this bridge is that the bridge was bypassed by a new highway bridge with the historic bridge being preserved in place for pedestrian use. The only problem is someone went a little overkill with adding cyclone fencing to the railing, which is unsightly and obstructs the view of the truss. More attractive railings and barriers are available that can meet safety needs. Otherwise, the bridge appears to retain good historic integrity and is a good example of historic bridge preservation.
