West Silver Creek Bridge

Map 

Description 

The NBI lists this bridge as a multi-beam stringer with a deck of open steel grating. It is listed here as a pony truss, however, the NBI also states the bridge was reconstructed in 1998, not replaced, as originally shown in our data base. Whether or not a pony truss was replaced in 1998 or if there never was a pony truss in this location is unknown.
