The salt was loaded Thursday and the crews were ready to work into the morning as drivers waited to see what they woke up to.
"I'm hoping for a lot of snow, but I'm not expecting it," said James Finney, a driver in Charlotte.
What drivers do expect are safe roads for the commute.
It was raining all day Thursday, and the puddles on the roads all over Charlotte could turn to black ice.
Eyewitness News Meteorologists in Severe Weather Center 9 say that it will start freezing after 4 a.m. Friday and that it needs to stay freezing for an hour to create black ice. They say it won't start to thaw until 9 a.m.
That is why state and city crews are trying to hit the road at the right time.
"The critical moment is going to be when the temperature drops," said Linda Durrett, with the Charlotte Department of Transportation.
Crews want to beat the freeze to prevent some of the ice from forming, but they don't want the salt to wash away.
In the Charlotte area Eyewitness News is told NCDOT crews and about 50 contract trucks will be on the road.
The city of Charlotte said it will have 24 crew members and 12 trucks out targeting trouble spots.
"Black ice will be a concern in those areas that are usually flooded, the low-lying areas, which is bridges, culverts, curbs and gutters," said Durrett.
Drivers said they plan to take it slow Friday morning and if they have to, they will stay off the road.
"We have a really great environment so if it's bad they will tell us to work from home," said Cameron McElhany, a Charlotte driver.
The state and city said they are ready to work into the morning if needed.
