The $17.4 million project is about seven miles east of Lincolnton, Ga., on the highway that crosses Thurmond Lake into McCormick County, S.C.
“The contractor thinks there may have been some movement, and that’s why they’ve put out some seismic monitoring devices,” said Jill Goldberg, a spokeswoman for Georgia’s Department of Transportation, which is overseeing the project.
The bridge is about two years from completion and is not open to traffic.
“So if there is any issue with it, we will know about it long before then and it would be fixed,” Goldberg said.
The question involves possible movement of one of the piers, or footings, that are part of the 0.728-mile bridge replacement project.
The contractor is Alabama-based Scott Bridge Co. According to the company’s Web site, its largest single contract was the $192 million Interstate 20/Bobby Jones Expressway juncture in Augusta.
