Sawmill Road in New Fairfield will be closed next week at Woodcreek Road.  The closure is expected to last about a week.  Traffic delays are expected as the Candlewood Corners project moves north on Route 39. The work is being done to address undersized drainage, which officials also say is poorly aligned.  Flooding occurs because of that, damaging properties and causing hazardous driving conditions.  Two culverts, large enough to handle rain events without flooding of properties or roadways, are being installed. The project will take three to four months to complete.
