Winter maintenance

Cardiff Council has plans in place to ensure the city is kept moving during the winter period.

When are roads salted?


We usually carry out precautionary salting of roads whenever ice, frost, snow or freezing rain is forecast.


Salt is generally spread in advance of the sub-zero temperatures unless residual salt is remaining from previous salting events.


Deciding when to salt


A series of ice prediction outstations are present throughout the city. Up to the minute information is monitored by a duty officer who is available 24 hours a day from 1 November through to 31 March.


This enables a decision to be made on whether to pre-salt the highway network.


Which roads are salted?


With more than 600 miles of roads across Cardiff, it is not possible for all roads to be treated with salt when ice or snow is forecast so following consultation with transport providers, the police and emergency services, we have identified a priority network of routes that will be pre-salted when freezing conditions are forecast.


This network comprises of:


  • ​All A roads
  • The majority of B roads
  • some C roads
  • other non-classified roads 


Where the forecast does not require all of this network to be salted, only roads identified as colder than average and known wet areas will be treated.

Cycle routes


Cycle routes are only treated where they form part of the carriageway which is part of a designated salting route.


Are any footpaths salted?


A limited network of footways will be salted when ice or snow is forecast. A priority list of footways has been developed. 


The highest priority footpaths, based on footfall, are the main pedestrianised areas in the city centre. These will be pre-treated when local surface temperatures are forecast to fall below zero.

How is salting done?


Resources are on stand-by 24 hours a day between 1st November and 31st March to ensure that salting can be done as soon as it is needed.


We have 9 vehicles to spread salt on the roads and they are also fitted with ploughs to help with clearing snow from roads if needed.


What if my road is not salted?


Roads which are not part of a salting route may be provided with a salt bin if it meets the agreed criteria.


Salt bins


Salt containers are provided for use by members of the public and also the emergency services on the adopted highway. We will provide a salt container where a need has been identified on routes that are not on the pre-salting network.


There are currently more than 400 salt containers located across Cardiff.
