CHARLESTON, S.C. (AP) - South Carolina transportation officials are expanding bridge inspections after cracks were found in four interstate highway bridges.
70 bridges have been identified for inspections. Forty-1 of the bridges have been checked and are fine.
Cracks were found in steel-plated girders supporting four Interstate 77 bridges in York and Chester counties earlier this month. Transportation Secretary Buck Limehouse says inspectors determined there was no immediate danger and the bridges remain open.
Limehouse has ordered inspections of all bridges that have a similar age and design to the I-77 bridges. Most of the bridges were built in the 1960s and 1970s.
Sixteen of the bridges being checked are in Charleston, Beaufort, Dorchester and Jasper counties.
