Merthyr Tydfil County Borough Council as the Highway Authority, is responsible for providing a winter maintenance service. This enables us to assist the travelling public to use the county borough road network with reasonable safety throughout adverse winter weather. Our aim is to maintain or reinstate as quickly as possible free and safe traffic flow, on all routes during the winter period and to ensure that vehicles and pedestrians can use them with safety.

How do we decide when to treat the roads? 

Between 1st November and 31st March daily weather forecasts will be received from the Weather Forecast Provider. These are analysed very carefully and a decision is made on what action is required on that day.

Where the forecast does not give a clear indication of ice or snow the Council can call upon a number of road sensors around the county, which can give up to the minute information on the surface temperature of the road.

When we grit

Gritting usually takes place overnight during snow or icy road conditions. The gritting routes will be treated as a precaution and we will re-treat the area if snow or ice is still present after precautionary treatment.

We will carry out a precautionary treatment if either snow has been forecast, or if freezing conditions occur immediately following rain.

If snow levels build up, snow ploughs will be used.

When do we start ploughing the snow?

We usually start snow ploughing once the snow reaches a depth of about 50mm. Dedicated snow ploughs are mobilised and as well as ploughing the snow will deposit salt onto the road surface to help reduce the build up.

Grit bins

Because grit bins can be vandalised or misused they are only provided if there is a genuine need for them. Requests for grit bins at new locations are considered against various criteria and only provided if the need for them is justified.

As such, the Council will not be in a position to take any new requests, or make decisions on the unprecedented number of applications already received, until after the end of Winter.

How do I report an empty a grit bin?

Although we monitor and replenish grit bins on a regular basis, during cold weather the grit level in these bins may become low.

If you wish to request a New Grit Bin, A Grit Bin Refill or Report a Missing or Vandalised Grit Bin, Please use our Winter Maintenance Online Request Form

When contacting us, please can you provide the following information:

Where is the grit bin located? (Please provide as much detail as possible including landmarks such as it’s located next to the Post Office, Pub etc).

Useful advice on traveling in winter weather

Only travel if your journey is necessary - could you use public transport instead?

In advance of your journey check the Internet, television, teletext or listen to local radio for the latest weather and travel information.

When driving in snow or icy conditions, slow down and ensure your stopping distance is suitable for the traffic speed and weather conditions. Steer gently and avoid harsh braking or sudden maneuvers as these could cause loss of control.

Allow plenty of time for your journey

Ensure your windows and mirrors are free from snow, frost and ice, use a suitable de-icing solution in your windscreen washer fluid and check the levels frequently.

Make sure your wiper blades aren’t worn, so you can keep your windscreen as clean as possible, and remove any snow that might fall off into the path of other road users.

You will need more tyre tread in wet or icy conditions. Ensure that your tyres are inflated to the manufacturers’ recommended pressures and have at least 3mm of tread depth.

Check your lights are clean and in working order and use dipped headlights if driving during snowfall.

Get a garage to check your car battery is in a good condition and also check the level and strength of the antifreeze in your vehicle's radiator.

If going on a long journey take a shovel, torch, Wellington boots, warm clothing, food and a hot drink.

If you break down try and get your car to a safe place off the carriageway. If this is not possible or if you get stuck in snow, it may be safer to leave your vehicle. If so, stand a safe distance away, but make sure that you are visible to other road users whilst waiting for assistance. If possible keep your sidelights on if it is dark or if the visibility is poor and do not stand (or let anybody else stand) between your vehicle and oncoming traffic.
