Transportation officials have been monitoring this storm since last week, because preparation starts even before the first snow flake falls.
Crews spent much of the morning pre-treating roads.
That treatment can go on as early as a day in advance, but experts wanted to wait and see what the forecast called for today before making a decision.
Officials say this storm poses a bigger problem because of the threat of ice.
Areas that are expected to get wintery mix cannot be pre-treated, which can make clean up difficult.
"By pre-treating that salt next or that's on the road helps keep any of the moisture from forming a bond. Once that bond is formed it's really difficult to break away that ice and we have to wait for temperatures to rise because salt actually isn't as effective under 20°, so that's a challenge for us as well," said Cher of INDOT.
INDOT officials say they are fully stocked with salt to tackle this winter storm.
Crews will once again be working around the clock in 12 hour shifts to keep the roads clear.
