Winter service map and plan
We carry out winter service operations from 1 November to 31 March each year, extending into April if conditions require. Our fleet consists of 21 gritters and 4 tow-behind units. Last winter we used around 4,000 tonnes of salt treating our roads, footways and salt bins.
How we prioritise gritting
We prioritise our gritting routes based on the traffic volume, usage and layout of each road. Routes are divided into three priority levels:
Priority 1 - treated first, on receipt of a frost, ice or snow warning. Target completion: 8am.
Priority 2 - treated after all Priority 1 routes are complete, when adverse conditions are apparent. Target completion: 10am. Priority 2S routes are treated on school days only.
Priority 3 - not routinely salted or gritted. Snow clearance only where conditions prevent access.
Evening targets are 4pm for Priority 1 routes and 6pm for Priority 2 routes.
Winter service by the numbers
- 73% (714km) of our road network is treated as Priority 1 or 2
- In 2024-25 there were 81 Priority 1 responses and 30 Priority 2 responses
- The cost of winter service in 2024-25 was just over £1.37 million
- 82 roads (97.8km) are upgraded from Priority 3 to Priority 2 before school bus movements - updated annually in consultation with the Education team
- School and care facility car parks are included in treatment routes
- We have two weather stations - on the A960 at Kirkwall Airport and on the A967 at Mill of Rango in Sandwick - which, together with thermal mapping of the entire road network, help us predict when temperatures will drop below freezing
- There are 462 salt bins across Orkney, most on Priority 3 routes
- Two seasonal ice warning signs are displayed from 1 November to 31 March - at Rashieburn on the A961 at Holm, and at Bridgend on the Old Finstown Road in Firth

Common questions
How do we know when to treat our roads?
How do we know when to treat our roads?
We receive a weather forecast specifically for the Orkney area, giving us road surface temperature predictions. We send out gritting crews before temperatures are predicted to fall close to or below freezing. It takes around two hours to cover Priority 1 routes, and the grit needs time to work on the road surface. We also consider when temperatures are due to rise, to decide the best time to treat Priority 1 and Priority 2 routes in the morning.
Why don't you grit roads before 6am or after 6pm?
Why don't you grit roads before 6am or after 6pm?
This is based on the resources available - the size of our workforce, safe driver hours legislation and the miles of priority routes our gritters need to cover - and the level of traffic needed to activate the salt effectively. If you are on the roads early in the morning or after the main evening rush, the effects of treatment will be reduced, so please take extra care.
Can my road be added to the primary gritting routes?
Can my road be added to the primary gritting routes?
The current priority routes were established through a comprehensive consultation and evaluation process. You can review the Winter Service Policy to see the criteria used to assign road priorities. To request your road be considered for future inclusion, email roadssupport@orkney.gov.uk explaining why you think your road should be on a primary route. Requests will not be responded to individually but will be considered as part of the next major Winter Service review.
Can you clear private roads, car parks or driveways?
Can you clear private roads, car parks or driveways?
No. We are only responsible for public roads. Private roads, car parks and driveways are the responsibility of the owner or occupier.
Why has the gritter only gritted one side of the road?
Why has the gritter only gritted one side of the road?
On narrow roads, the gritter may only be able to treat one side to avoid oncoming traffic. The salt will spread across the full road surface through traffic movement.
Why is the gritter not spreading grit while it's driving?
Why is the gritter not spreading grit while it's driving?
The gritter may be travelling to or from a depot, or moving between routes. Spreading salt on untargeted roads wastes resources and can damage road surfaces and the environment.
When will my road be cleared of snow?
When will my road be cleared of snow?
Priority 3 roads are only cleared of snow when conditions prevent access. Priority 1 and 2 routes are cleared as part of normal operations. If you are on a Priority 3 route, please allow extra time and check conditions before travelling.
Why don't you grit my cul-de-sac?
Why don't you grit my cul-de-sac?
Cul-de-sacs are generally on Priority 3 routes as they carry low traffic volumes. Salt bins are provided in many areas to allow residents to treat their own street. Check the interactive map to find your nearest salt bin.
I'm a cyclist - what about me?
I'm a cyclist - what about me?
Priority 1 footways are treated where resources allow. Cyclists should take extra care on untreated roads and paths and consider whether conditions are safe for cycling.
Will you grit my road if I have an emergency?
Will you grit my road if I have an emergency?
If you have an emergency, call 999. In life-threatening situations the emergency services can request treatment of specific routes outside normal operating hours.
Can I make a special request for my road to be gritted or cleared of snow?
Can I make a special request for my road to be gritted or cleared of snow?
We cannot respond to individual requests during winter operations as resources are focused on priority routes. You can email roadssupport@orkney.gov.uk to request consideration for future route reviews.
Can local contractors help by gritting or ploughing snow?
Can local contractors help by gritting or ploughing snow?
Yes, where conditions are severe and resources are stretched, we may engage local contractors for snow clearing. If you are a contractor interested in being considered, contact roadssupport@orkney.gov.uk.
What about footways?
What about footways?
Footways are treated on a priority basis. Priority 1 footways in Kirkwall and Stromness are treated as part of normal operations. Other footways may be treated when resources allow. The self-help salt bins can be used by residents to treat footways near their home.
What about salt bins?
What about salt bins?
There are 462 salt bins across Orkney, most on Priority 3 routes. Use the interactive map to find your nearest bin. If a bin is running low, please contact Customer Services on 01856 873535. If no salt is available, a small amount of sand or ash can be used to provide grip.

Winter Service Policy 2026-31
This document contains Orkney Islands Council’s Winter Service Policy for 2026–2031, setting out how roads, footways, cycleways, car parks and island routes will be treated during severe winter weather. It explains route priorities, salting and snow-clearing standards, emergency cover, salt bins, staffing, safety, equipment, weather forecasting and communication arrangements. The policy uses a risk-based approach, with higher-priority routes serving key facilities treated first, and includes arrangements for annual planning, performance monitoring and review.
