The high snowfalls and bitterly cold days of January and February have kept Norfolk’s snowplow drivers busy and made serious inroads on the town’s supply of road salt. As of mid-February, First Selectman Sue Dyer reports, the town had spent $130,000 on salt, or $30,000 more than budgeted. At $85/ton, the Public Works Department has sprinkled some 1,500 tons of salt on town roads so far this winter.
