 After entering Muhlenberg County, KY 70 goes through mainly northern areas of that county, including intersections with Kentucky Routes 175, and 181, before reaching the Central City area, where it would join US 431 for a little while.In Central City, US 431 and KY 70 both meet US Route 62, and then traverse the exit 58 interchange of the Wendell H. Ford Western Kentucky Parkway (also known as the WK Parkway).That interchange was a former toll booth site until the 1987 discontinuation of the WK Parkway's toll plazas.
