TWIN ARCH CULVERT

This Twin Arch stone culvert is located on the east side of County Road 25A north of Troy, Ohio near the hospital. It is listed on the U.S. Department of the Interior’s National Register of Historic Places.

Engineered by Samuel C. Forrer, the culvert was contracted to be built by Loring R. Brownell and Norman Summer of Darke County with completion expected in 1836. Their work however was delayed by an outbreak of cholera so John Kline completed the project in 1837 using German immigrant workers. Its purpose was to allow a small ditch to flow underneath the Miami and Erie Canal and empty into the Great Miami River. Only one other similar canal structure is known to exist in Ohio, that one is in Shelby County near New Bern and in an advanced state of disrepair. RMB
