Interstate 124 - Chattanooga

Downtown Chattanooga map - AARoads

Interstate 124 was fully completed by the late 1980s and signed as such until that time. Apparently confusion among drivers between "I-24" and "I-124" led officials to remove Interstate 124 signage in favor of just signing the route as just U.S. 27.1
