SANIBEL, Fla.- Crews spent the day under the Sanibel Causeway inspecting the bridge on Friday.

The Lee County Department of Transportation paid a company $160,000 to monitor hairline cracks in the support beams. They first showed up in 2009, just a couple of years after the bridge was built.

Officials say the bridge is safe.

A report should be completed in a couple of months.
