Located on the west side of Glenwood, this concrete arch bridge crosses a small tributary of Keg Creek between Jamett Road and US-34.
Built in 1902, the bridge consists of a single concrete arch span, perhaps with a brick roof inside as well. If there is a brick roof, it has since been covered up by mortar or a thin layer of concrete.
Along this line, dozens of these arches were built during the relocation and double tracking, as they were considered to be permanent structures that needed very little attention once constructed.
Overall, the bridge appears to be in fair to good condition, with some spalling noted throughout the structure.

The author has ranked this bridge as being locally signification, due to the common design.
