The Tennessee Department of Transportation is working to regain momentum after freezing temperatures have put many road improvements on hold.
TDOT officials told Nashville's News 2 Friday once temperatures dip below 32 degrees crews are unable to lay pavement.
"We do have a lot of patching now. The roads are kind of coming apart because of the temperatures, so we have to do a lot of patching," TDOT District Supervisor Burrell Tidwell said.
Tidwell said the department has also had to deal with many employees battling the flu.
"A lot of our workforce is sick with the flu and it's really taken a toll on us," he said.
Due to the unexpected smaller projects that need to be handled first, Tidwell said construction projects such as road widening projects on 65 South, Concord Road and State Route 1 are behind by a few weeks.
"It's just a few areas around town and you can only work 9 a.m. to 3 p.m. during the day and that's just not a whole lot of time to do very much maintenance anymore," he said.
Tidwell added TDOT crews have also gotten behind on litter pickup due to the bitter temperatures.
