Winter gritting routes

Find information about our winter roads service including the roads in County Durham which are identified as gritting routes.

Our road gritting service

Pre-salting (gritting) is the laying of rock salt before frosty conditions. It stops ice forming on the road surface. Our road network is split into priority 1 and priority 2 routes.

Priority 1 routes: These routes typically include all of the A roads and the majority of the B roads, most bus routes and other busy areas.
Priority 2 routes: In times of prolonged severe weather we will also treat some minor and C roads, as resources become available.

See which roads are gritted by postcode or area, in normal conditions (priority 1 routes) and in extreme weather or longer periods of predicted frost (priority 2 routes).

The A1, A19 and A66 roads are managed by Highways England.
