Danbury is looking for bids on some surplus materials. The City switched to all salt to treat the roads in winter, and is looking to get rid of the sand-salt mixture it used in the past. Several surrounding communities, including Bethel and New Fairfield, still use a mixture to treat the roads pre-winter storms. Mayor Mark Boughton says they have had several interested municipalities contact Public Works so the surplus material will have to be sold off to the highest bidder. Boughton says the salt-only treatment means less street sweeping and less material collecting in the storm drains.
