During the winter season, the Department reports winter road conditions on the major State routes on its home page on the Internet. This work is accomplished with MoDOT's maintenance personnel supplemented with part-time emergency workers, as needed. Priorities for snow removal operations are established for each maintenance unit. The continuous treatment routes, including Interstates, receive first priority. Second priority is given to other primary and supplementary routes with high traffic volumes, specific priorities being governed by traffic density and danger spots.
Third priority is given to the remainder of the supplementary system routes.
