The Fort Griffin Iron Truss Bridge is the oldest functioning bridge in Shackelford County, Texas, and one of the state's oldest remaining trusses. It is also the last remaining pin-connected Pratt through truss in the county. Because it has survived with few alterations, the Fort Griffin Iron Truss Bridge is a remarkably intact example of an early metal truss bridge in Texas. Built to accommodate traffic between the county seats at Albany and Throckmorton, the bridge cuts through what used to Fort Griffin, a military checkpoint and cattle town. The Fort Griffin Iron Truss Bridge was nominated to the National Register of Historic Places in 1979.

Fort Griffin Bridge
Posted October 26, 2020, by Craig F (craig [at] fenter [dot] com)

From what I understand as of October 2020. The Fort Griffin bridge is no longer functional, and has not been for some time. Although it is on a county road, travel there is discouraged for reasons explained below.

I inquired about the bridge at the Fort Griffin Historic Site visitors center, and I quote; "although the road is county road, the bridge is not passable, this would force you to turn around on private land." Apparently the landowner has seen some issues with trespassing and vandalism at the Fort Griffin town site, which is apparently on private land just before the bridge.

I drove to the area, and can confirm the road does not appear maintained beyond the residence entrance on the road prior to the bridge. Note: I did not leave the county road.

I did not continue to the bridge site or even the town site, though I could clearly see the buildings. Out of respect for the landowner I did not pursue visiting the bridge.
