During the summer of 1950, the Kentucky Department of Highways placed a lean concrete mix for base construction and widening in Montgomery County. This project was a 4.415 mile section of U.S. 60 on the Winchester-Mt. Sterling Road, and was designed as SF 87-117. Four major revisions – three alignment and one grade – were completed on the project thus requiring full-width base replacement of sections of the old pavement with the lean concrete mix.
