Plowing Priorities

Snow and ice control operations are limited by the resources available (specifically:  budget, personnel, equipment and materials). Due to these limited resources, the level of service for snow and ice control has been associated with the Department’s established highway corridor priorities. 

For each highway corridor priority, target route lengths will dictate the normal cycle times that can be expected based upon average conditions, while local geographic and/or geometric factors will dictate whether particular routes need to be longer or shorter than average.  In addition, during a winter storm event, the level of service for all routes will typically be reduced between the hours of 10:00 P.M. and 4:00 A.M, depending upon specific storm conditions. 

The following table provides an overview of the various goals associated with each corridor priority.
