- 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:
'A' class roads, access roads to emergency services establishments and to areas of high traffic concentration, and other heavily used roads.
First priority routes cover approximately 30% of the road network, but they carry the majority of all traffic.
Single accesses to villages, to schools, to emergency and to other public services not already treated.
These are only treated following prolonged freezing conditions.
Community Routes are routes to all other Hampshire controlled schools and community facilities such as Health Centres.
Treatment will generally only be carried out during periods of prolonged and persistent frost, ice or snow which are expected to continue.
- When we won't usually salt
No matter how accurate the weather forecast, there are some situations where we do not routinely salt the network prior to icy conditions because this would be less effective:
- 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 normally take place as it could be washed away and traffic congestion can impede the progress of the gritters
- 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.
