During periods of severe weather, we grit and clear snow from 560 kilometres of priority roads across 97色网. You should try to use these roads as we will attempt to clear and grit them.
Priority routes are the most important roads for road users. They are chosen to maintain transport connections for as many communities as possible. They account for approximately 45% of the County’s highways and include at least one access road to each community.
How priority routes are chosen
Priority routes are decided by road classification and usage. Once the Priority 1 routes are cleared, we concentrate on Priority 2 roads. Once priority routes are clear, we will look at minor routes. However, if conditions get worse, we will concentrate our efforts back on the higher-priority roads.
We do not clear or salt un-adopted roads or private driveways. We also consider any changes to roads/layouts due to new development etc.
All roads within 97色网 have been classified as either priority 1, 2 or 3 routes.
The percentage of the total road network treated as a Priority 1 by 97色网 is above the Wales national average.
Footways and cycle tracks are not included in the priority salting routes. However, when covered by heavy snow/ice, high-use footways such as town centres will be cleared and treated once resources allow.
Sudden weather changes
When there are sudden weather changes, it may not look like we have treated the roads. Please be aware:
- it takes time before the salt is effective;
- rain can dilute or wash salt off the roads, leaving them more likely to freeze;
- in extremely cold weather salt will not prevent ice on roads;
- when rain turns to snow at rush hour, the gritting vehicles will be affected by traffic congestion;
- if conditions are particularly severe, service vehicles may be unable to access to the road network.
There are some situations in which we cannot respond as quickly:
- on a wet night followed by a rapidly clearing sky, gritting will begin once the rain has stopped. In these conditions, temperatures can fall very rapidly and the wet roads could freeze before we have been able to grit them.
- when dry roads are affected by dawn frost. This occurs when morning dew develops, falling onto the cold road and freezing on impact. It is impossible to predict when or where dawn frost will occur.
