Starting tonight the Mid-Bay Bridge in Okaloosa County will be closed for several hours for repairs. In January an inspection found several corroded cables, which will have to be replaced. The bridge will be closed to all traffic between 11 p.m. tonight and 5 a.m. Tuesday, but completely replacing the corroded cables is expected to take until this fall. Until repairs are completed traffic is limited to two-axle cars and trucks, school buses, and emergency vehicles.
