- Priority order for road salting
We routinely treat only the first priority routes in the event of forecasted ice, frost or snow. We carry out this treatment in advance of the forecasted conditions to achieve the most effective results. Lower priority roads are not treated in this way.
The order we salt roads:
Take extra care driving during severe weather, and don't assume all roads have been treated.
- When we won't salt
No matter how accurate the weather forecast, there are some situations where we do not salt the network prior to icy conditions because this would be ineffective:
- When rain is followed by rapidly clearing skies, salting will normally start soon after the rain has stopped (to avoid the salt being washed away). Sometimes temperatures can fall rapidly following rainfall and the wet roads may well freeze before we have been able to treat them.
- Rush hour snowfall. When rain turns to snow coinciding with the rush hour, early salting would not take place as it would be washed away and gritters can often not make progress due to traffic congestion.
- Pavements and footpaths
Busy pedestrian routes will only be salted at times of prolonged sub-zero temperatures and when there is persistent frost or ice.
Other pavements and footpaths are not salted.
- Cycle tracks
Cycle tracks which are part of the road are treated as designated by the road priority.
Cycle tracks which are part of the footway network are treated as the footway treatment designation.
