Sandy & Beaver Canal Locks 51-54 and Grimms Bridge & Tunnel

Grimms Bridge: (Archived Bridge Hunter; Bridge Hunter; Historic Bridges; Satellite)

The lock locations are approximate because I could not find any ruins in the satellite images. And the river has moved since some of the maps were drawn.

"Built 1884 by the Wrought Iron Bridge Co.; rehabilitated 1960 and 1997" The span is 154' (47m). [BridgeHunter_bridge]

"This is a spectacular example of the Wrought Iron Bridge Company's work, a ten panel Whipple through truss with pinned connections." "Double-intersection Pratt trusses, also known as Whipple or Murphy-Whipple trusses, were among the most successful of long-span thru truss designs (up to 300' long) of the 1860s to 1890s for both railroad and vehicular crossings." [HistoricBridges]

Given the rather old date of 1884, I wonder if this bridge is made with iron instead of steel.

Gimms Tunnel

The tunnel was built in 1933 for the Youngstown & Southern Railroad. It is 1200' (366m) long. [BridgeHunter_tunnel]

Sandy and Beaver Canal Lock E#52

Sandy and Beaver Canal posted
Lock 52, eastern division. St. Clair Township, Columbiana County, Ohio. Below Grimm’s Bridge on Little Beaver Creek.

Seth Watkins commented on the above post
I'd say this is the stone they used up the hill from the lock.

Sandy and Beaver Canal: Seth Watkins quarry marks evident. Very cool!

It is interesting that the two mills did paper instead of grain or lumber.

I found a satellite image that has less tree coverage. The map and photo implies the lock is on the south side of the river just downstream from a bend in the river. But I can't find it. Grimms Bridge is in the upper-left corner of this excerpt. Today's river has bigger meanders than when the above map was drawn.
