Which roads do you salt/grit?

Posted on 25 January 2017

The primary salting network is made up of the major routes where the majority of vehicle movements take place and also includes accesses to hospitals, ambulance stations, fire stations, other emergency service establishments, railway stations, airports and secondary schools. The length of the 37 routes which form the primary salting network is 20% of the road network.
