History
Highway 251 was authorized on July 1, 1949.

The route was paved between Clarks Grove and Maple Island and between Corning and U.S. 218 at the time it was marked. Originally, the highway turned south at the county line and followed present-day County Road 2 east to U.S. 218. The highway was moved to its current alignment in 1952. This new routing, as well as the remaining gravel portion of the roadway, was paved in 1954 or 1955.

Highway 251 originally extended into Clarks Grove proper to intersect U.S. 65 (present-day County Road 45) until Interstate 35 was built.
