Gritting Routes and what they mean.

Featured Image

There have been Four groups of roads Torbay Council have identified within the primary salting network which have been taken from from the Thermal Maps of Torbay. All these routes, or a combination of these routes can be selected at any time for treatment. The four colours of the groups are Red, Blue, Green and Yellow. Red is the coldest area and Yellow is the warmest.

See below for the areas covered in each group: MAP

Primary Salting Network…What does it all mean?

Throughout Torbay we have a primary salting Network made up of strategic routes to include:

  • Main distributors
  • Link roads
  • Bus routes that have services that start before 8am, or where they are carrying traffic from a larger village to a strategic route or a main distributor. 
  • Access to fire, police ambulance and royal mail stations.
  • Bus Depots

To make sure all services can continue as normal as possible, included is any roads that join neighbouring highway authorities gritted networks.

In Torbay the total Highway network stretches across 520km,  and the Torbay Primary salting network covers 192km of all Torbay roads.

It is not an easy process to know when and where needs to be gritted, a thermal mapping survey of the highway network is first carried out on behalf of Torbay Council as this enables thermal differences between known locations on the network to be identified ready for various weather scenarios. This information is then taken and compared with the weather forecasts sent through meaning an effective prediction can be made of the locations and time of day/night that the gritting needs to take place.
