KNOXVILLE (WATE) - Winter weather kept road crews hard at work over the past few days. We've seen them pre-treat, plow, and re-treat roads with salt, brine, and sometimes sand or gravel. Monday's brutal cold just adds to the challenge.

The Tennessee Department of Transportation warns that once the sun sets the likelihood of black ice and slick spots increases, and so far on Monday no major issues were reported.

Thousands of pounds of salt were put to good use in the last 24 hours, which seems like a first so far in this mild winter.

"We're fine as far as salt and brine mix are concerned. We continually monitor weather forecasts," said Mark Nagi with TDOT.

Since Sunday night at 6 p.m., crews have been looking for slick spots and spreading salt mix, although there are challenges.

"Certainly these are some dangerously low temperatures. When it gets to be around 25 degrees or lower, we'll add calcium chloride to the salt. It really helps," said Nagi.

It essentially prevents re-freezing.

"However as temps drop even more into the teens and under 10-degrees that's when effectiveness really lessens," said Nagi.

Despite that, crews will work around the clock on their routes until this winter weather has rolled out of here. Until then, TDOT warns to give yourself extra braking room if you drive and only leave home if necessary.
