The transportation cabinet says maintenance to some Bowling Green roads will cause detours.
Anyone normally taking Old Louisville Road will be detoured to the U.S. 31W and U.S. 68 Louisville Road Bridge.
The detour is expected to last all month while the State Street Bridge undergoes repairs.
Workers are removing the lead-based paint on the bridge to prevent rusting.
Transportation cabinet reports say in 2004 more than 12,000 cars pass the effected section of Old Louisville Road each day.
