A busy stretch of Interstate 77 could be closed for nearly a month, but the South Carolina Department of Transportation said that's the worst-case scenario.
SCDOT officials said they would work through the night to fix the hole on I-77 at Celanese Road. However, that could just be the beginning.
SCDOT engineers found the structure of the bridge starting to separate underneath. The question they still have is whether that's a temporary fix.
More than 71,000 cars and trucks ride on the I-77 bridge over Celanese Road every day. That wear and tear tore open a pothole, which was found Tuesday.
It became a much bigger issue just today when engineers walked the length of the bride and discovered that rebar beneath the surface was separating from the concrete. The bridge is 41 years old, and putting a Band-Aid on it may not be enough.
What they don't know yet is just how serious this is.
"The worst-case scenario would be a situation where we had to come in and cut out parts of the bridge deck or replace that part of the bridge deck and everything involved," said Vic Edwards, a SCDOT engineer.
