SANIBEL, Fla.- Crews are making repairs to the Sanibel Causeway.

A few years ago, an inspection revealed some hair-line cracks in support beams. The county says while the bridge is safe, it's important to repair what they call normal wear and tear.

Drivers can expect to see cranes and crews working on the causeway. Work has begun, but crews haven't started using any of that heavy machinery yet on the bridge.

There is no concern as to whether the bridge is still structurally sound. This project all came about after an inspection in June recommended crews come out and repair cracks identified on the bridge structure. Repairs would prevent salt water from intruding into the bridge and damaging the the steel and rebar.

Crews are expected to work on the bridge until September 30th from 9:00 a.m. - 4:00 p.m. Although there will be slight lane shifts in place, there are not expected to be any closures to lanes or the bridge itself. DOT also advises morning and afternoon commuters should not be impacted as work is starting before and after rush hour times.
