Winter Maintenance

Keeping Scotland Moving

BEAR Scotland delivers winter maintenance as part of the North West, North East and South East Trunk Road Units for on behalf of Transport Scotland. This involves clearing snow on some of the highest trunk roads in the UK, as well as treating roads ahead of frost and ice forming and salting footpaths. We also provide the winter service for M80 and A92 DBFO contracts.

Our teams work hard in difficult conditions to keep roads clear and safe to help keep Scotland moving, whatever the weather.

The winter period runs from 1 October to 15 May each year.

Our current winter fleet of over 150 vehicles is available 24/7 throughout the winter period, ranging from huge 32-tonne eight wheeler spreaders to fast-track tractors fitted with ploughs or snow blowers capable of shifting over 600 tonnes of snow in an hour

The fleet is operated by over 290 trained winter operatives. We have a dedicated weather forecaster for each of our units who are contracted to provide a forecast for each of our spreader routes by midday for the coming 24 hour period. The treatment plan for the day is then drawn up which proposes our planned actions for the afternoon and night ahead. Our control room and Winter Service Duty Officers then monitor conditions for the period and take appropriate action where necessary.


What's Involved

Precautionary Treatments

The main focus is to carry out precautionary treatments to prevent ice forming. Every day BEAR Scotland receives detailed weather forecasts which predict which roads are expected to experience below freezing conditions and at what time. To help stop ice forming, winter spreaders then treat the roads before the temperature drops. This is usually late afternoon (before peak traffic) and sometimes again overnight to make sure the roads have been treated before the morning peak. The spreaders used for precautionary treatments and patrols are equipped for pre-wetted salting. Pre-wetted salting uses brine mixed with dry salt immediately prior to spreading to help it stick to the road surface and start the melting process. During last year’s harsh winter BEAR Scotland used over 67,000 tonnes of de-icing materials across 8385  treatments.


Winter Patrols

24 overnight winter patrols cover the North East, North West and South East of Scotland, as well as the M80 DBFO. Winter patrol vehicles carry out reactive salt treatments and also record real-time road surface temperature data through on-board sensors which is fed to the 24/7 control room.

Winter Fleet

BEAR Scotland’s 177 strong dedicated winter fleet includes:

  • 60 large, 32-tonne eight-wheeler spreaders – some of the largest in the UK.
  • 10 new 26-tonne six-wheeler spreaders

Control Room

The BEAR Scotland Control Rooms operate 24/7 and continuously monitors conditions across all the trunk roads BEAR Scotland is responsible for. The team help to monitor in real time the changes in temperature or weather conditions across the network, with the help of roadside weather stations across the network to help provide real-time, accurate information on conditions which is fed directly into the control room. The team can then arrange for additional gritters to reach any areas which require assistance should the weather takes a turn.

Freeze and Thaw Cycle: How Road Defects Form

A road pavement has a natural life cycle and at some point it will require maintenance, repair and replacement. While most of these repair and replacement projects can be planned, sometimes a road surface can fail prematurely. Such failure can happen over the course of months, or it can be very sudden.


Queensferry Crossing Ice Monitoring

New weather sensors on the Queensferry Crossing allow us to monitor and respond to the specific weather conditions that we know can cause ice to form on the cables.
