The Colemanville Covered Bridge was originally built in 1856 by James C. Carpenter at a cost of $2,244. After being damaged twice by flooding, it was partially rebuilt in 1938 by Edmund Gardner and 1973 by David Esh. Lancaster county completely rebuilt the bridge in 1992 for $350,000. During the restoration process the bridge was raised by 6 feet (1.8 m) and moved west a few feet to protect it from damage in potential future flooding.
