There is a winter weather advisory in place for tonight and tomorrow. Danbury Mayor Mark Boughton says the City is using a different product this year to keep the roads safe.
Boughton says the initial cost to use the straight salt material that's treated with a compound will be a little higher than the old sand and salt mixture, but in the long run it will save money on clean up costs from street sweeping.
The product is effective at lower temperatures than sand and salt combined.
It's been used on Main Street for the past three years, and Boughton says it's worked great there.
