Our aim is to make Northamptonshire's roads as safe as is practical and ensure that you can travel with a minimum of delay and disruption during severe winter weather.
Which roads are gritted?
The roads we are responsible for gritting are split into two categories:
- the precautionary network (P1); and
- the adverse network (P2)
Motorways and trunk roads (e.g. M1, A14, M45, A45 east of Northampton, A5 and A43 south of Northampton) are gritted by
What is the P1 network and when is it gritted?
If ice and/or snow are forecast, we prioritise gritting all other A roads and B roads, traffic sensitive roads and other roads, including at least one road to a village community. These roads are called the precautionary network (P1) and cover 46% of the total road network.
The aim is to treat P1 roads after the evening peak traffic time, though the target time for action otherwise depends on forecast and conditions.
What is the P2 network and when is it gritted?
The adverse network (P2) covers certain links to villages not on the P1 network and also certain bus routes and selected roads in industrial estates.
When forecast weather conditions are unlikely to improve for at least 48 hours, or the temperature is unlikely to rise above freezing in that time, gritting will only be carried out on the P2 network if the P1 network does not require treatment.
Occasionally, gritting arrangements do not go to plan. You should never assume that a road has been treated but should drive in accordance with the prevailing conditions.
Please remember that the majority of minor roads will receive no treatment at all.
