Winter’s on its way and the gritters are ready for action

Posted in Connect on October 23, 2018.


With the winter season upon us, Mayo County Council is urging drivers to always drive to the weather conditions in order to keep safe on the roads.
Gritters are geared up for call outs of the winter season and Local salt barns have been piled to capacity ahead of this winter.
Mayo County Council delivers an annual winter maintenance service with gritters on standby 24 hours a day, seven days a week throughout the season, which runs from the 15th October until 30th April each year.
Salt barns and salt storage facilities will contain over 5000 tonnes of salt. The County Council’s fleet of 2 No. 9m salt spreaders, 12 No. 6m salt spreaders, 6 No. 2m salt spreaders and 3 No tractor spreaders are available when required. Precautionary gritting is normally done late in the evening, before the coldest temperatures arrive, consideration is made not to send gritters out too early, especially if rain water could wash salt away. The TII procures bureau weather services to assist Mayo County Council in predicting when frost, ice or snow may occur on the road network. These services are currently provided by a combination of Met Éireann and Vaisala.

There are over 60 staff involved in the provision of the winter service during normal winter weather including Winter Service Manager, Duty Engineers, District Engineers, and Winter Service Operatives. This number is increased during severe weather as resources allow.

Mr Paul Dolan Head Of Roads, said:
“Keeping the roads safe during winter is both a science and an art. Our carefully planned gritting routes cover 1,075 km of road across 23 treatment routes which equates to 100% of the national primary network,100% of the national secondary network, 82% of regional roads and 3% of the local road network.
“We monitor and analyse a range of forecasts so roads are treated when the salt will be most effective. Salt lowers the freezing temperature of water, making ice less likely to form, so we have to carry out precautionary gritting before any ice. We then undertake reactive gritting as needed in response to accumulations of snow and ice during severe wintery weather.”
“Even with the most careful and thorough planning, the use of special Met Office forecasts and the latest ice prediction technology, winter service is really a battle against the elements and ice-free roads cannot be guaranteed. Motorists have to play their part by taking extra care during wintry conditions. The best advice is in the rules of the road – drive with care even if roads have been salted, be prepared for road conditions changing over short distances and take care when overtaking gritters.”
• Despite the resources that are applied to providing the winter service, ice-free roads cannot be guaranteed. The motorist should remember the following:
In Ireland there are a high risk proportion of marginal nights when temperatures are very close to zero. This makes it more difficult to accurately predict ice than in colder countries.
It takes a number of hours to organise salting operations and salt a route, so any journey may start or end on an untreated section of the route.
In heavy rain or high winds, salt can be washed away or blown away and the wet surface may subsequently freeze if the temperature falls below zero.
Tips for staying safe on the roads this winter:
• When clearing snow, do not use hot water – this will melt the snow but will replace it with black ice!
• Always consider if your journey is necessary when contemplating driving in wintery weather. Check local traffic bulletins and if you have to drive, make sure all windows and lights are clear of snow or frost. Make sure you have de-icer and a scraper with you.
• Adjust your driving to the conditions. Brake earlier and gently and manoeuvre with care. Also take a torch, blanket, some food, warm clothing, a mobile phone and a spade with you just in case you have any problems.
• If you do have to abandon your vehicle in really bad conditions, be careful and try not to cause an obstruction. Emergency vehicles and gritters are large vehicles and may need to get past.
