Of the 479 bridges in Horry County, the Federal Highway Administration considers 18 in poor condition. The agency evaluates factors like culverts and decks to rate bridges as good, fair or poor.

However, a poor rating doesn’t mean a bridge is structurally unsound.

“A bridge rated in poor condition likely needs repair or rehabilitation to restore its original design capacity but that rating is not, in itself, an indication of a safety issue,” said Nancy Singer of the FHWA Office of Public Affairs.

Still, bridges in poor condition deemed safe may require weight limits and more frequent monitoring. In Horry County, 29 bridges have posted weight limits, according to SCDOT media relations manager Hannah Robinson.

“Several of these bridges have been awarded to contractors to begin repairs or replacements. Some are in the planning stages,” Robinson said in an email, without specifying which structures have work planned. “Safety is our number one priority – SCDOT immediately closes any bridge that is unsafe for travel and has a rigorous inspection program.”
