The Ravenel Bridge was expected to remain closed at least until sometime Friday morning because of the danger of falling ice.
The bridge was closed all day Thursday, snarling traffic between Mount Pleasant and Charleston.
Local police and transportation officials will continue to monitor the bridge and decide when it should be re-opened, Derrec Becker, a spokesman for the state's Emergency Management Division, said Thursday night.
While many roadways have improved since the storm first hit, conditions remain dangerous on the Ravenel Bridge and elsewhere, he said.
"Roads are still bad statewide ... we are still in a state of emergency," he said.
Motorists had hoped the Ravenel Bridge would reopen for the 5 p.m. commute, but such was not the case.
"Following an afternoon inspection of the weather conditions on the Ravenel Bridge, the Mount Pleasant Police Department, Charleston Police Department and SCDOT have determined that the bridge should remain closed to maintain the safety of the public," Charleston and Mount Pleasant police announced at 4:30 p.m.
The bridge has been closed because of the danger of ice falling from the overhead cables as it melts. There is no estimate on when it will reopen.
"The chunks of ice that are coming off the bridge are much harder than they were in the last event," Mount Pleasant Mayor Linda Page said late Thursday afternoon. "They're not shattering when they hit the roadbed. They're just kind of bombs. It's actually more dangerous than it was two weeks ago."
The Don Holt Bridge over I-526 remained open as an alternate route between Charleston and Mount Pleasant. Traffic, however, was backed up well onto Interstate 26 as Mount Pleasant-bound commuters slowly funneled toward the Don Holt.
Magrath Darby Boulevard, which is near the bridge in Mount Pleasant, was also closed Thursday afternoon because of chunks of ice falling from Channel 2's tower, Page said.
