DRD ROADS SERVICE PREPARED FOR WINTER WEATHER
From now, until the end of March, DRD Roads Service will have 160 staff on standby, every night, to salt roads, to help keep traffic on main roads flowing freely and safely in wintry conditions.
Roads Service provides a winter gritting service from November to March every year. This is a massive logistical undertaking that involves salting nearly 7,000 kilometres of roads, in just over three hours, across Northern Ireland, at a cost of £74,000 per night.
A DRD Roads Service spokesperson asked motorists to drive carefully in wintry conditions: "Despite the high quality of the salting operation, ice-free roads cannot be guaranteed. Rainfall can wash salt away and the wet surface may re-freeze.
"I appeal to all motorists to heed the advice in the Highway Code; drive with care, even if roads have been salted, be prepared for road conditions changing over short distances and take care when overtaking gritters.
"Nearly £1.1 million has been allocated for this year’s winter salting operation in Roads Service’s Western Division which includes Omagh, Enniskillen, Strabane, Magherafelt, Cookstown and Dungannon and their surrounding areas. The operation involves almost 12,000 tonnes of salt and a fleet of 28 gritters and drivers to salt a network of 1630km (1015 miles) of roads, within a timescale of just over three hours.
"However, even with the most careful and thorough planning and use of state-of-the-art technology, winter maintenance is a battle against nature and in exceptional winter conditions, there is bound to be some disruption.
"The salting operation is vital to keep main road traffic moving in wintry conditions and, in line with the procedures agreed by the Assembly, £5 million is set aside for this essential work. On average, there are around 75 call outs each year and a massive 63,000 tonnes of salt is spread by Roads Service to keep main road traffic moving in frost or snow."
Engineers use state-of-the-art technology to assist with the operation, including ice sensors linked to 17 weather stations across Northern Ireland, installed in conjunction with the Meteorological Office (Met Office), and thermal mapping of all roads on the network. The Met Office uses information from the stations, along with their own data, to provide forecasts, which are transmitted to engineers’ computers.
The DRD Roads Service spokesperson explained: "Roads Service ensures that motorists are kept fully up to date with road conditions at this time of year. Information on salting activities is relayed electronically to the broadcast media, to ensure the latest news on road conditions is available to motorists. Our winter service leaflet is also available to help inform the public about winter driving.
"It is Roads Service’s policy to salt main through routes, carrying more than 1,500 vehicles per day and other busy through routes, carrying more than 1,000 vehicles per day, where there are difficult circumstances, such as steep hills. In applying the criteria, buses get a high weighting, a 40-seater bus is counted as 40 vehicles. Efforts are made to ensure that small settlements of more than 100 dwellings, have a salted link via the shortest route to the salted network and consideration is given to placing grit piles or salt boxes at hills, bends or junctions on roads that are not salted.
"During long periods of heavy snowfall, maximum effort will be concentrated on the key traffic routes. Clearing snow from motorways and the trunk roads will be given priority, before moving to ‘A’ class roads and the busiest urban link roads. Once these main routes are open to traffic, Roads Service’s resources will be diverted to the less heavily trafficked roads, especially in urban areas, and will continue until all roads are cleared. Contractors and farmers may also be employed to clear blocked roads.
"The salted network is around 6,800 km (4,225 miles) and covers 28% of Northern Ireland’s roads and caters for 80% of traffic. Whilst I can understand the concerns of those who use the more lightly trafficked roads that are not included in the salted network, it is simply not practical to salt all roads. To cover 90% of traffic, we would have to double the size of the treated network and the cost would double to £10 million."
