Flooding from Hurricane Florence has closed down a section of Interstate 95 in Dillon County, according to the South Carolina Department of Transportation.
The interstate is shut down between exits 181 and 190, which lead to SC routes 38 and 34.
Motorists should avoid this area, which is between Dillon and Oak Grove.
For detours, the agency said I-85 through South Carolina is open to traffic from North Carolina to Georgia. From Georgia, I-95 northbound to I-26 westbound to I-77 northbound into North Carolina is open to traffic.
Most other major roadways remained open as of midday Sunday, though the status changed rapidly throughout the morning. As of 9 a.m., 74 roads had been closed across the state.
Flash flooding from rainfall forced temporary closures on Highway 96 in Marion County.
SCDOT's website features an interactive map of road conditions and closures across the state.
In the long-term, emergency officials expressed more concern about potential closures due to expected river flooding, which remains far from the forecasted peaks.
SCDOT continued construction of temporary dams Sunday in attempt to keep the main arteries to Myrtle Beach open, including U.S. 501.
Some lanes on 501 were closedSunday due to flash flooding.
This is why hundreds of cars are backed up on 501. A decently powerful stream has overtaken the road and bridge. DOT and police are there but a single lane of traffic continued to come through. pic.twitter.com/ixupirGzEE— Andrew Brown (@Andy_Ed_Brown) September 16, 2018
