Atlanta’s Department of Public Works crews have been working around the clock to clear snow and ice off the city’s roads, a press release from the city says.

The DPW began pre-treating Priority 1 and 2 routes and bridges on Jan. 16 before precipitation began. Residents are still urged to be cautious on roads, which may have patches of ice remaining.

By the end of Tuesday night, the Department had 14 salt spreaders on the roadways, treated 925 lane miles and used 724 tons of salt, the city said. Department of Watershed Management officials also responded to three water main breaks.

The city announced Thursday evening that city will reopen Friday.

“The City will resume normal operations tomorrow, Friday, Jan. 19, 2018,” a notice from the city says. “Please still use caution during your commute as black ice still poses a hazard.”

MARTA is also scaling back services for Friday due to the weather. More from MARTA:
