Winter service is an important part of Transport for Buckinghamshire's (TfB) maintenance work. It involves:

  • salting major roads when there is a risk of ice
  • clearing snow
  • reacting to other weather related emergencies

Read more about how we decide when to grit the roads and information about our salt bins.


Gritting routes

There are 3 separate gritting routes, precautionary, snow, and secondary.

Snow routes and secondary routes are the reduced network we revert to these in times of very severe weather.

Precautionary routes

These are the most important routes to keep everyone moving. The routes consist of 1405km of the county's A and B road network, about 44% of the total network.

Click on each route to see the map. If you are unable to see the maps, there is also a text summary for each route.

Snow routes

When heavy snow comes, we may move to a 24hr and focus on the county's most strategic routes (around 22% of the overall network). This will continue as long as it snows (normally around 3 days) during which time only some A and B roads will be gritted. 

Once the snow has cleared, we go back to the precautionary routes as soon as possible.

Secondary routes

These may be gritted before a heavy snow or if the snow carries on for a long time. The are done after the primary routes have been cleared and treated.

They include the following highway network:

  • classified roads which are not included in the primary salting network
  • unclassified roads serving communities of 200 dwellings or more and unclassified roads with a gradient of 10% or less

We may also salt cycleways and footways in main shopping areas and other key pedestrian and cycle facilities. The secondary salting network will be treated after the formation of ice or fall of snow in accordance with the Operational Plan.
