Business Loop Interstate 45F serves the Navarro County seat of Corsicana in northeastern Texas. The loop follows the original alignment of U.S. 75 and a portion of U.S. 287 through Corsicana as Interstate 45 bypasses the city to the east. The 6.37 mile route comprises a four-lane highway with a short viaduct over Texas 31 (7th Avenue / Martin Luther King, Jr. Boulevard) outside Downtown. It was established on June 21, 1990 in a mileage transfer from State Loop 564.
