Carriageway Gritting

During snow and ice conditions, a priority system for carriageway gritting is in place to make sure that the key routes in the borough are kept open. Higher priority roads will be treated first, and once the conditions on these routes are satisfactory, lower priority roads will be gritted (if there is capacity to do so).

Some carriageways will be gritted before snow is forecast (known as pre-treatment), as well as when snow has actually fallen (known as post-treatment). Pre-treatment cannot be carried out too soon before snow is expected to start falling, otherwise the grit may be dispersed from the road surface by vehicles or melt-water, so during periods prior to forecast snowfall the council receives regular updates from the Met Office and we use these to try and ensure the timing of any pre-treatment will be as effective as possible.

Below is more detailed information on the different priority classifications:

• Carriageway Priority 1
• Carriageway Priority 1A
• Carriageway Priority 2
• Carriageway Priority 3
• Carriageway Resilience Network (applies only in the event of grit shortages)

All roads in the borough are listed by priority order in the Carriageways - Winter Service Priorities document, which can be downloaded from the attached files section at the bottom of the page.

Information on how to view the gritting routes using the Online Mapping function can be found in the maps section below.

Carriageway Priority 1

These are the most heavily trafficked and/or steepest carriageways, and those serving important locations (such as ambulance or fire stations) on less heavily trafficked roads.

• These roads will receive pre-treatment on the forecast of snow, within a few hours of when it is expected to start falling
• Ongoing post-treatment of these carriageways will continue as required in order to keep them open and safe to use

You can view our winter gritting map to see where the priority roads are located in Haringey.

Carriageway Priority 1A (schools)

These are carriageways that do not carry heavy traffic, but do serve schools. This classification only applies during term time. During periods of school holidays, these routes will be gritted according to their position in the standard set of priorities.

• These roads will receive pre-treatment on the forecast of snow, within a few hours of when it is expected to start falling, if we have been able to satisfactorily complete Carriageway Priority 1 pre-treatment
• Ongoing post-treatment of these carriageways will take place as often as required to keep them open, provided that Carriageway Priority 1 roads are fully operational

Carriageway Priority 2

These are moderately trafficked and less steep carriageways in the borough, and those serving locations where there are known groups of vulnerable people (such as residential care homes).

• There will be no pre-treatment on these carriageways
• Post-treatment of these carriageways will be carried out, provided we have been able to adequately treat Priority 1 and 1A roads to keep them open

You can view our winter gritting map to see where the priority roads are located in Haringey.

Carriageway Priority 3

These are the least trafficked and lowest gradient carriageways in the borough.

• There will be no pre-treatment on these carriageways
• These carriageways may receive post-treatment during ongoing snow conditions to support the provision of refuse and recycling collections, or if there is capacity to undertake gritting once higher priority carriageways have been satisfactorily treated

Carriageway Resilience Network

In the event of an ongoing and widespread snow weather event, the supplies of grit salt may not meet the demand. This would mean that the council may not have sufficient stocks to be able to satisfactorily treat the Carriageway Priority 1 routes.

The Carriageway Resilience Network comprises the roads that have been agreed with Transport for London as essential to keep London moving. In the rare event of a grit shortage, only these streets will receive ongoing treatment.

You can view our winter gritting map to see where the Carriageway Resilience Network is located in Haringey.

A list of the roads that are part of the Carriageway Resilience Network can also be found in the attached files section at the bottom of this page, along with a large high-resolution map.
