It’s the job of Colas and the council to keep roads clear. Precautionary salting is carried out when we receive notification of icy conditions from the Met Office and local weather stations. Roads are treated mostly at night or in the early hours of the morning to avoid traffic. We would not advise clearing the roads yourself.
Colas concentrate on the roads agreed with the council to be priorities, such as the vital transport routes in and out of the city, major bus routes, and major routes to hospitals, schools, shopping centres and other public services. These are marked as priority 1 or priority 2 roads on the map available below.
In the case of heavy snowfall, once priority roads have been cleared, Colas will try to manually or mechanically clear other roads.
The M27 and the A27 trunk road are maintained by the Government's Highways England (HE). Portsmouth City Council and HE share responsibility for the M275.
