This is a bridge where even with any historic significance set aside, should be preserved for its aesthetic value. Its pleasant arch shape, coupled with attractive v-lacing on some members make this a beautiful bridge. In addition, Slippery Rock Creek is indeed filled with rocks, and this bridges location near some mill ruins makes this a very scenic area. The old mill ruins has left a rapids-like feature in the river.
This is a polygonal Warren pony truss with no vertical members. It is supported by stone abutments. Original pole railings remain on the bridge. There is v-lacing on some diagonals. This bridge was designed by Thomas Gilkey, an engineer who designed a wide variety of truss structures for Lawrence County, including the newer span of the Churchill Road Bridge, and the Mahoning Avenue Viaduct. Gilkey traditionally favored pin connections, even into the 1910s, but apparently by the 1920s he gave them up and switched to riveted connections as seen on this bridge. This bridge was a good example of a bridge designed by a local engineer who did a substantial amount of bridge work in the local area.
