Gritting routes

Our team is on standby from the start of November to the last week of March. Using information about the weather and road conditions from a number of sources (the METEOGROUP, road sensors and visual inspections of road conditions) our highways engineers will decide whether to take action and salt.

Once gritting is required it is undertaken in a planned way, with priority given to major and important routes first (Precautionary routes), with other roads being treated after that (Secondary routes).

Types of gritting/salting routes

When the roads need salting/gritting routes are prioritised using the Code of Practice for Highway Maintenance Management,  Well Maintained Highways , issued by the UK Roads Liaison Group (COP)

Precautionary salting routes

These are based on the amount of traffic that uses the route and a number of other factors that road users thought were important for the salting network:

  • principal and main roads (those carrying at least 3000 vehicles per day)
  • important bus routes
  • routes to hospitals
  • roads leading to ambulance stations, fire stations and police stations
  • bus routes adjacent to or serving schools
  • selected hills

The council aims to treat all precautionary salting routes in North Lincolnshire within three hours of the gritters being mobilised.

There are currently nine precautionary salting routes. Details of the precautionary salting routes can be found on our interactive  gritting routes map

Secondary salting groups

In addition to the precautionary salting route there is a network of secondary routes that will be treated when all precautionary routes have been treated. However these will only be treated if:

  • air temperatures remain below zero degrees centigrade for more than 24 hours continuously and/or
  • there is a clearly identified problem caused by snow or ice on the highway

Secondary routes meet the following criteria:

  • a route on a relatively steep hill
  • a route, which for a significant length, is next to a deep drainage ditch, river or similar
  • local bus routes not included elsewhere
  • pedestrianised area of Brigg and Scunthorpe, Frodingham footbridge and Ashby Broadway
  • additional routes that provide links for gritting vehicles
  • main routes next to schools (that can be accessed by a gritting vehicle)
  • main industrial estates

Reduced precautionary salting network at times of salt shortage

During recent winters prolonged periods of cold weather across many parts of the country has resulted in a shortage of rock salt.

Whilst there are national strategic stockpiles of salt, there may be times when salt use has to be reduced to preserve stocks. In this case there is a reduced precautionary network, which includes priority 1 routes in snow and ice conditions, routes to key infrastructure and selected routes with particular access difficulties.
