Priority is given to maintaining safe driving conditions on those most frequently used routes. It would be prohibitively expensive to treat every side street and minor road.
The council also provides grit boxes on a self-help basis for some steep minor roads.
About 20% of the road network carries 80% of the traffic, and Wigan Council will grit to prevent ice from forming on the borough's main road network every night when icy conditions are forecast. The Highways Agency has responsibility for the M6 motorway running through the borough.
