You can view a map of our winter gritting route by going to

  • On the top left, select the 'map layers' button
  • Select 'driver information'
  • Then select 'winter gritting routes'
  • The route will appear over the top of the map in purple and becomes clearer when you zoom in.

We aim to make sure our roads are safe for road users and keep traffic moving by:

  • Spreading salt to prevent ice forming or to help thaw ice and snow
  • Clearing snow where more than five centimetres has built up on roads

Our gritting vehicles and crews

We have seven gritting vehicles and a Land Rover and trailer for less accessible areas.

We employee a full-time night shift to carry out gritting work as well as employing a number of drivers (who are volunteers) to carry out gritting work in addition to their normal day job. These volunteers work for the city council’s highways, ground and cleansing sections and are all trained LGV drivers with specialist skills associated with winter maintenance tasks.

Salt/grit stocks

Grit salt is stocked at designated areas throughout the city which give a level of resilience that, is enough for the council gritters to turn out 120 times in frost conditions and 30 times in snow conditions during the season. Should conditions mean that additional callouts are required then the city council has arrangements with salt mines to obtain additional stock.

Salt/grit spread rates

Spread rates depend on the weather conditions. In frost conditions we spread at a rate of 10grms per m2, in ice conditions we spread at 20grms per m2 and when it snows we spread at 2 X 20grms per m2 for up to 50mm of snow, we also use snow ploughs.

Where do we treat?

Approximately 260km of roads will be treated each time the gritters are called out. This includes all major roads, regular and frequent bus routes, plus some infrequent bus routes which are part of the main network. Also, access roads to emergency services including police, ambulance stations and hospitals.

We also have around 400 self-help salt bins located around the city. These are filled when required during the season. Please call us on: 01782 237061 to request a grit bin be refilled.

See instructions for viewing the gritting map on at the top of the page.

How are decisions made?

The duty officer/decision maker decides whether or not to turn out. He/she visits the Met Office weather prediction website each morning before making a decision. The prediction service tells us the likely road surface temperature, air temperature, rain prediction, wind prediction and direction and the likelihood of snow and frost. There are also sensors in the surface of key roads around the county which help us make more informed decisions.
