Indiana is well known for its covered bridges – 98 still stand across the state. The largest and most famous concentration of them is in Parke County. You can spend many enjoyable hours driving around Indiana seeing them all; you can still drive across a few of them.
But seldom do you get to see one, um, undressed.
This is the Medora Covered Bridge, and it’s undergoing restoration. It was built in 1875 by J. J. Daniels, one of the leading covered bridge builders in the state. With three spans, at 431 feet, 10 inches, it is the longest covered bridge in the United States.
Those curved beams in the bridge identify it as a Burr arch truss bridge. Engineers disagree about whether the arch bears the load and the Howe truss (the vertical and angled beams) provide stability or vice-versa. But one thing’s for sure – combining the arch with the Howe truss gives a stronger bridge than either alone.
Can you imagine how dark this bridge must be when its roof is complete and the sides are attached? Given that and my general nervousness about driving on wooden bridges, I’m very happy that this bridge was retired from service in 1972. (This photo shows the bridge while it was still in service.) I’ll drive over the modern UCEB (ugly concrete eyesore bridge) next to it, thank you. But I’m eager to return after the restoration is complete so I can walk it end to end.
