Fort Steuben Bridge

The Ohio River is crossed by some large suspension bridges. This 1928 steel-wire suspension bridge carries old US-22 between Steubenville, OH and Weirton, WV. Note the Warren truss-work to stiffen the deck - a feature of virtually all suspension bridges. The bridge is still in service but scheduled for demolition in 2009 as it has been essentially replaced by the cable stay bridge partially visible in the background. The photo was taken from the Ohio side at a boat launch area.

This Pratt pinned through truss bridge was moved to Arion Road over Scioto Brush Creek, Scioto County in 1944. Such reuse was common during WW II due to metal shortages. The location of the original site and bridge age is unknown but it appears 19th century. Don O'Brien reported (8/2007) that this picturesque historic bridge has been removed by the county.

Old CR-82 Bridge

Built by the Wrought Iron Bridge Co. in 1883 just SW of Zoar in Tuscarawas County on a now abandoned section of County Road 82 this bridge was faithfully restored in 2004 for use on the Zoar Valley Trail as a pedestrian bridge. The iron 3-span Pratt pinned through truss bridge is a rare early example of continuous span construction. It crosses the Tuscarawas River.

Massillon Lattice Bowstring

This rare iron bowstring bridge is just north of Dillonvale in Jefferson County. Remarkably it is still in service on Township Highway 125 but may have been moved here long ago from another location. The design of the lattice arch indicates it was built in the 19 century by the Massillon Bridge Company. Modifications to the deck supports have been made but the arch appears original. It's posted for 10 tons but has been rated "intolerable" by the CE and I fear for its future. The Laymon Road Bridge exhibited in Clinton County is a similar example by this builder.
