BLUEWATER BAY — The Mid-Bay Bridge between the Destin and Niceville areas will be closed to all traffic from 11 p.m. Friday to 5 a.m. Saturday as workers continue to make permanent repairs.

Drivers will have to use alternative routes during the closure.

Repairs to the post-tensioning tendons, which are pre-stressed steel cables inside the bridge that reinforce concrete, are expected to be completed this fall, according to the state Department of Transportation.

Until then, bridge traffic will remain limited to two-axle vehicles including cars, trucks, SUVs, school buses and limited EMS and first responder equipment. Semitrailers and commercial vehicles will be required to use alternate routes until permanent repairs are completed.

Message boards on both ends of the bridge alert drivers to the temporary restrictions.
