(KPLR) - MoDOT trucks have been out for much of the day pre-treating ahead of any winter weather that moves into the St. Louis area Tuesday night.
Trucks have been leaving the MoDOT yard on Ballas then pre-treating Highway 40. They're putting down a salt brine that will help melt any light snow that falls.
The brine should do the job if snow amounts to less than a half an inch.
We're told if there is more than half an inch then the plows will come out.
MoDOT officials say about 100 trucks are on the streets, trying to make sure they hit all of the major roads before nightfall.
Becky Allmeroth, MoDOT: 'All day today our trucks are out pre-treating, spraying that salt brine, getting ready- we have additional crews coming in at seven o`clock so we`ll have about 100 trucks out overnight just to be on the safe side and be ready in case roads do start to become slick.'
Allmeroth says there could be some busy days ahead for road crews.
