A tractor-trailer carrying giant windmill parts slammed into the edge of the Cosgrove Avenue overpass in North Charleston on Wednesday and lodged the trailer under the bridge.

The accident about 5:45 p.m. on Meeting Street Road sent concrete chunks of the overpass crashing to the road and closed traffic for hours Wednesday on Meeting Street Road and Cosgrove Avenue. No one was injured.

All but one lane of the busy overpass reopened by about 8 p.m.

"It looks like we've got one beam that is heavily damaged on the outside of the bridge," said Robert Clark, Lowcountry district engineering administrator for the S.C. Department of Transportation. "That (outside eastbound) lane will be closed off for tonight until the morning so we can do further assessment. It's pretty dark out there."

The 18-wheeler from A&N Trucking Co. of Edisto Island was transporting three nearly 10-foot-tall steel windmill components from the State Ports Authority's Wando Welch Terminal to a warehouse on Meeting Street Road, said Arthur Burnell, a driver dispatched to continue the trip.

One of the parts clipped the bottom of the overpass, which is marked at 14 feet and 2 inches. Two parts tumbled into the street, and the third lodged between the trailer and the bridge and brought the 18-wheeler to a halt.

"It was too tall for the bridge," said Alvin Swails, who was on his way home from work on Meeting Street Road.

"I just misjudged the height," said a man who identified himself as the driver of the truck but declined to give his name or comment further.

Whether anyone will be charged in the accident is under investigation, said Spencer Pryor, North Charleston police public information officer.
