The county council grits 1,869 miles of priority roads in Lincolnshire when road temperatures drop to around 1°C. This includes:
- All A and B roads
- At least one road from each of the county’s main villages to a major traffic route
- At least one road within 500m of all train and bus stations, hospitals and schools, where possible
- Additional roads depending on various risk factors, such as historic accident data
The Highways Agency is responsible for gritting all trunk roads in Lincolnshire, including on the A1, the A52 Grantham to Nottingham and the A46 west of Lincoln.
No other roads will be treated by the county council, except during severe snow conditions or prolonged icy spells. The Resilient Road Network map shows our priority routes during severe weather, including flooding. It is reviewed and published annually.
From October to April, we work with the Met Office to monitor the weather conditions and our 43 gritting crews are ready to respond 24 hours a day.
When we grit, we try to do so either before ice has set or once snow has settled so that it has the best chance of working.
Even when we’ve gritted a road, it doesn’t mean it won’t be icy. This is because:
- It takes time for the salt to take effect
- High winds or sudden rain can take salt off the road
- If the road surface temperature drops to below -7°C, gritting becomes much less effective
- If the road surface temperature drops to below -15°C, gritting doesn’t work at all
For local route maps and advice, download the gritting routes and winter advice leaflet.
The criteria for which roads are gritted is set out in our winter maintenance plan. All routes are reviewed regularly but, due to the cost, we are unable to grit all 5,000 miles of road in Lincolnshire.
You can request to a route to be added by calling 01522 782070. Requests will be reviewed between April and September but additions are unlikely as the network is already at full capacity.
