LIQUID CACL LENDS HAND IN INDIANA SNOW BATTLE

The article describes Indianopolis' methods for clearing snow, and how liquid calcium chloride has become a major part of the city's effort to keep traffic flowing smoothly. With 3,100 miles of streets and roads to clear, salt and salt prewetted with 32% calcium chloride is used. Calcium chloride is dispensed at the rate of about 5 to 8 gallons per ton of salt. Sand treated with calcium chloride is used at intersections in areas without storm sewers. Planning for snow clearance is important. Key arteries that serve commuter routes, school bus routes, and access to hospitals have been identified, and efforts to clear roads start with the first snow alert. The response needed during a storm is determined by analyzing data from three sources of weather information: national weather service and local airport forecasts; and a private weather service. The latter forecasts not only wind and temperature data, but also, pavement temperature for the next 24 hours. The city's efforts are coordinated by keeping in touch with its 8 districts via telephone.
