Check which roads are gritted
Suffolk Highways is responsible for the delivery of these services in Suffolk except for trunk roads, which are the responsibility of Highways England. The winter season runs each year from 1 October to 30 April.
How to use the map
- Enter in a location, street name or postcode
- Zoom in or out of the map using the + or - buttons
- After a few seconds only the roads that we treat will show in purple (primary route) or green (secondary route)
- Move the cursor over a highlighted route for more information
The routes we salt and grit and when
When ice or snow is forecast we treat all:
- A and B roads
- roads to 24 hour fire stations, accident and emergency hospitals, main bus and railway stations
These roads are prioritised into 2 categories.
Primary routes (P1 - purple)
We aim to complete Primary (P1) routes before the onset of hazardous conditions – and within 2 hours 30 minutes of starting the treatment.
Timing is calculated from starting from the depot to completing of salting.
If ice or snow continues we will salt or grit other roads, but only when we know that traffic is moving freely and safely on our P1 routes.
Secondary routes (P2 - green)
Secondary (P2) routes are generally run when the hazard is expected to remain after 9am.
Consideration will also be given to morning treatments in the event of a morning heavy frost as indicated in the forecast
Both these situations will be subject to the needs of the P1 network.
- We aim to complete Secondary (P2) routes by 7.30am.
Combined both of these routes cover approximately 51% of all roads maintained by Suffolk County Council. Find out more in our winter service plan (PDF, 830KB).
How we keep roads free from snow and ice
We decide to spread salt on the roads by working closely with our weather forecaster, and use information from our own weather monitoring stations.
What does salting do?
Spreading salt on the roads helps to prevent or remove ice. However, it becomes less effective as temperatures reduce.
In exceptionally low temperatures, salt may have little or no effect. In these cases it may be necessary to spread grit to give more grip on the ice, rather than trying to melt it.
When snow is more than 50mm deep, it needs to be mechanically removed by ploughing or digging. There are practical limitations to what can be achieved, and priority is always given to roads carrying the most traffic or important bus routes.

Salting and gritting
Suffolk Highways will only consider requests for new roads to be added to the gritting routes, new grit bin requests or requests to refill the grit bins from the relevant parish, town or district council.
We stock 2100 grit bins across the county at important locations, such as the bottom of hills, or on junctions on minor roads. Read more about grit bins.
Information on how local communities can get involved with snow clearance activities can be found in our Community Preparedness - Winter Gritting pack (PDF, 1.19MB).
Clearing snow or ice at home
You can clear snow and ice on the pavement outside your property or from public spaces. It's unlikely you'll be sued or held legally responsible for any injuries on the path if you have cleared it carefully - follow the snow code (PDF) when clearing snow and ice.
Dealing with snow
We have contracts with over 200 farmers and contractors across the county to help with clearing snow and ice. We also use our own equipment.
We will carry out snow ploughing throughout the night in severe snow conditions. We do this to keep the most important roads passable (this is normally confined to the busier A class roads). There could be considerable delay in clearing snow from some minor roads.
We also clear snow from heavily used pavements. Priority is given to:
- main shopping streets in town centres
- other town pavements
- well used cycle tracks
