FORT WALTON BEACH ― Engineers will return to Fort Walton Beach on Monday to take another look at Brooks Bridge after a run-in with a passing dredge caused minor damage, officials say.

Florida Department of Transportation District 3 spokesman Ian Satter confirmed Sunday the fender system was struck and suffered minor damage, and stabilizers on the dredge, called “spuds,” scraped the bottom of the bridge, creating a couple of small gouges on the bridge beams.

Officials closed the bridge Saturday night until a team of engineers and divers from FDOT could conduct an inspection to make sure it was structurally sound. The bridge was reopened to pedestrian and vehicular traffic at about 1:25 a.m. Sunday.

“We’re going to get back to the bridge to assess if repairs are needed,” Satter said.

Investigators from Coast Guard Sector Mobile are looking into the incident, but no other information could be released until they have completed their investigation, said Lt. j.g. Juston Lee of Sector Mobile.

The closure resulted in a massive traffic jam that stretched across Okaloosa Island and all the way into Destin.

Witnesses say the bridge appeared to shake when the stabilizers scraped the underside.

“It hit the bridge hard enough to shake it,” said Okaloosa County Sheriff’s Office spokeswoman Michele Nicholson.

Shortly after 1 a.m. FDOT tweeted “All lanes open on Brooks Bridge after inspection finds the bridge is structurally sound.”

Lee identified the Inland Cardinal as the name of the tugboat propelling the dredge. According to online records, the Inland Cardinal is an 80-foot, twin-screw tug owned by Inland Dredging Company LLC of Dyersburg, Tennessee.
