Columbia, SC (WLTX) - The South Carolina Department of Transportation says they're working to prevent another road defect like the one that slowed traffic on Interstate 26 late Monday.

SCDOT says heavy rainfall and pavement issues caused the road to buckle between Airport Boulevard and U.S. 1 in the eastbound lanes. It caused a hole to form that would have been a hazard to drivers.

"Typically that bond stays there it became delaminated, where they separated and that separation caused the issue," said Andrew Leaphart, the chief engineer for SCDOT. "We'll monitor and we'll make sure that if anything like that happens again we'll be able to respond quickly."

Crews had to go in and drain the road, and that caused a problem during the afternoon rush hour. Traffic did reopen by Tuesday morning.

I-26 is one of the busiest highways in the state and SCDOT is well aware of that fact, which is why chief engineer Andrew Leaphart says he and his staff are looking for a permanent solution to the problem.

"It was a tremendous inconvenience and we want to avoid that at all costs," he said.

Transportation crews will finish revamping the road next spring. Leaphart says they plan to put $50 million towards a road safety plan in the near future.
