Nightime detours affecting Arthur Ravenel Jr. Bridge ramps and lanes will happen for four days starting this Sunday to allow maintenace and repairs, officials said Thursday.

The 9 p.m. to 5 a.m. work will also happen Oct. 14-17.

Meanwhile, state bridge maintenace engineer Lee Floyd said equipment used to inspect the bridge deck has been shut-down because of safety concerns.

The bridge maintenance and repair work will mean detours for the East Bay Street and Morrison Drive on-and-off ramps and the Coleman and Johnnie Dodds boulevards off-ramps. Lane closures on the bridge will also happen, said contractor Infrastructure Corporation of America.

Bridge traffic will still flow during the work but motorists will follow routes delineated by barricades, cones, signs and flashing arrows.

DOT spokesman James Law said workers will put epoxy sealant on ramp decks.

“It’s just a top seal to protect the joint where the concrete meets,” he said.
