The Allen County Highway Department is already making its plans for the upcoming season.
Department uses several types of vehicles for snow and ice control – five graders, 27 tandem-axle dump trucks, seven single-axle dump trucks and four one-ton small dump trucks. ACHD also uses ten heavy-duty pickup trucks to help clear road intersections and smaller areas.
Allen County is divided into north and south districts with 12 zones in each district. Each zone will have at least one truck, and some will have two or more trucks. Graders are assigned to gravel roads, areas with large drifts of snow and clearing berms of snow build-ups.
The anti-icing materials used are sand, salt, calcium chloride and stone chips. A sand-salt mixture will be used on most roads. Calcium chloride mixed with sand and salt will be used on roads that need to be cleaned to bare pavement. Stone chips will be used on gravel roads when they become slippery.
On higher traffic count highways, liquid calcium chloride will be applied along with a salt-sand mixture or pure salt. 36 trucks are outfitted with systems that dispense the liquid onto the salt and sand. The calcium chloride solution speeds the chemical reaction of the salt, which in turn melts snow and ice much quicker.
Snow removal will begin when the roadways are determined to be too slippery or a significant amount of accumulation is covering the road surface.
Allen County will use the statewide travel advisory system to warn motorists about hazardous conditions on county highways. Travel advisories fall into one of three categories:
Advisory, the lowest level, means that routine travel or activities may be restricted in areas because of a hazardous situation and individuals should use caution or avoid those areas.
Watch, means that conditions are threatening to the safety of the public. Only essential travel, such as to and from work or in emergency situations, is recommended. Businesses, schools, government agencies and other organizations should implement their emergency action plans.
Warning, the highest level, means that travel may be restricted to emergency management workers only. During a warning, the public is directed to refrain from all travel; comply with necessary emergency measures; cooperate with public officials and disaster services forces in executing emergency operations plans; and obey and comply with directions from properly identified officers. More specific restrictions, including parking restrictions, may be included.
