All the lanes of the Don Holt Bridge are open again, and traffic is crawling from North Charleston to Mount Pleasant.
A car fire snarled traffic on the bridge this afternoon.
The fire around the Virginia Avenue exit was reported about 4:20 p.m., North Charleston Fire Department spokeswoman Bianca Sancic said.
Cell-phone photos showed thick, black smoke billowing up through the girders of the bridge.
Firefighters extinguished the blaze at 4:42 p.m., Sancic said. No injuries were reported.
One lane opened again about 4:45 p.m., and all lanes were open by 5:30 p.m. Traffic is backed up on Interstate 26 and the Arthur Ravenel Jr. Bridge as a a result of the closure.
