This bridge is a sad case. Due to deterioration, it closed to all traffic in 2015.

This road was part of the 1914 Dixie Highway and, later, State Road 37, southeast of Martinsville, Indiana. This bridge came along in 1925. In the 1970s, SR 37 was upgraded to a four-lane expressway between Indianapolis and Bloomington, leaving lots of curvy old alignments behind. The new SR 37 is only about 500 feet northwest of this spot. I explored them all in a 2007 road trip; read all about it here.

This bridge is on a short old alignment that provided access to some county roads on the north edge of the Morgan-Monroe State Forest. While it was still open it got only about 500 vehicles a day. So it’s not surprising that Morgan County went lax on this bridge’s maintenance.

And now it’s closed to traffic. It’s all overgrown now; it looks like it’s been abandoned for decades. See it here.

It’s not clear what will happen to this bridge. SR 37 is in the process of being improved to become Interstate 69. Many of the nearby old alignments were or will be used as frontage roads, and have received improvements to support that. But project maps show frontage-road construction ending at the southern end of this old alignment. Will this bridge be left in place? Will it be removed?
