Ellis Lock & Dam #11 on, and 1913 Aban/Pennsy Bridge #12 over, Muskingum River upstream of Zanesville, OH

If you are here because of "BNSF/Santa Fe Trestle over  Ellison Creek east of Media, IL," then you need to go there.

Are they doing repairs, or did Ohio give up on this waterway?

Note the 1913 date. That flood destroyed and closed all of the canals in Ohio.

The old span is a pin-connected Whipple truss, and the new spans are rivet-connected Warren trusses. The original Whipple trusses were deck trusses. The Whipple truss that survived the flood was converted to a through truss when locks and dams were added to the river to allow "slack water navitation." [HistoricBridges]
