Priority 1 Pavements
The Council pre-treats Priority 1 pavements when snow is forecast in order to prevent ice forming on the pavement’s surface. These pavements will be pre-treated by resources from the Council's Street Scene Service before the start of the morning rush hour by using small manually operated spreading machines. Priority one pavements consist of heavily used locations, on steep gradients, or immediately leading to Transport Hubs.
In times of snow, Priority 1 routes will be gritted first and until these routes are found to be safe and running, treatment of Priority 2 routes will not commence.
Carriageways on these highways are pre-treated with grit (rock salt) when ice or frost may form. Gritting is normally carried out at night, starting when the evening traffic peak is over.
