Emergency repairs were underway Tuesday afternoon to a bridge deck pothole on Interstate 95 in Dorchester County, officials said.
The work, expected to take about four hours, required a shutdown of one lane of the southbound interstate at mile marker 75, said Gary Kinard, acting resident maintenance engineer for state Department of Transportation District 6.
The hole in the bridge surface was about one-foot by one-foot in size.
“It’s not very deep,” Kinard said.
The concrete cavity was mostly a danger to motorcyclists, he said.
“It really wouldn’t hurt a car,” he said.
Although a relatively minor issue, a pothole can turn into a larger problem unless it is addressed promptly, he said.
DOT workers based in St. George identified the needed bridge repair, he said.
Some I-95 bridges in South Carolina have had more serious problems.
One lane of the northbound interstate bridge over Lake Marion was shut in 2011 for concrete deck repairs that lasted two months. Two years earlier, the bridge required emergency repairs.
DOT, which maintains 8,383 bridges, has closed more than a dozen spans and restricted the weight on about 400 of them.
Three small bridges in York, Chesterfield and Cherokee counties were recently shut down after inspectors determined they were structurally unsound. Options for repair and/or replacement of the York and Chesterfield bridges are being investigated. DOT plans to replace the Cherokee span with one of its three temporary bridges until a new one can be funded, designed, permitted and constructed.
