Freezing rain and sleet are glazing the Lowcountry, leading officials to cancel classes in Charleston, Berkeley and Dorchester counties and close multiple bridges, including the Don Holt, Wando and Ravenel.
According to authorities, the Ravenel Bridge started slowly opening a few lanes at a time in both directions at about 12:15 p.m.
"The Ravenel Bridge is open to vehicle traffic but motorists are cautioned to keep their speeds slow due to possibility of patches of ice," says a press release from the Mount Pleasant Police Department. "Interstate 526 westbound is still closed due to severe ice on the Don Holt Bridge. Delays are expected. Officers are in the area offering assistance and diverting traffic as necessary."
Starting at about 1 p.m., Interstate 526 and the two bridges, the Don Holt and the Wando, were reopening.
The Mount Pleasant police department had closed the Don Holt and Wando bridges in both directions about 9 a.m.
In an earlier press release, the Mount Pleasant Police Department said:
"The Ravenel Bridge and Wando Bridge on 526 are closed temporarily due to icy conditions. This closure is expected to last only long enough for SCDOT maintenance vehicles to apply sand to the bridges. Delays are expected and drivers should use extreme caution operating in these conditions. Officers are in the area offering assistance and diverting traffic as necessary."
Authorities report that parts of the James Island Connector are iced over, causing cars to slide down sideways. The Berlin G. Myers overpass and the Limehouse Bridge were closed for much of the morning but both were reopened by 11 a.m.
S.C. Department of Transportation crews have been applying a brine solution to Lowcountry bridges and roadways to keep them from freezing since early Monday, according to James Law, spokesman for the district that includes Charleston County.
"We are putting brine solution on them as hard as we can go," Law said. "We've been working around the clock on this deal."
Law said it's up to law enforcement to close the bridges if they don't consider them passable. He said crews are monitoring the bridges and roads and are re-treated as soon as they refreeze.
"I don't know of anything else we could do that we're not doing," Law said.
According to the city of Charleston, the Westmoreland Bridge on I-526 and the Stono Bridge remain open.
The S.C. Highway Patrol is urging motorists to stay off the roads if possible.
Motorists reported downed tree limbs on Farmington Road in Summerville near Faith Assembly of God Church this afternoon.
For those who had to work today despite the nasty weather, the drive home should not be as perilous as the morning commute.
"We expect temperatures will remain above freezing through the evening commute," said Jon Jelsema, a meteorologist with the National Weather Service's Charleston office.
Motorists reported downed tree limbs on Farmington Road in Summerville near Faith Assembly of God Church.
Later tonight, temperatures may drop below freezing and roads may get icy, especially in areas further from the coast, such as Summerville or Moncks Corner, Jelsema said.
The steady rain is expected to end early this evening, but there will be patches of drizzle, he said.
Conditions for Tuesday morning will depend on how cold it gets tonight, Jelsema said.
"It's pretty difficult to forecast, when you are talking about one degree of temperature," Jelsema said. "At 32 degrees the rain freezes on the roads. At 33 degrees, it doesn't."
