State Roadwork Will Require Detour on Route 123 on April 12, 2021

The Connecticut Department of Transportation is announcing the replacement of a culvert under Route 123 (Smith Ridge Road) that will require detour of traffic northbound and southbound for 21 days from April 12 to May 2, 2021.  The project is located about 1.1 miles north of the intersection of Route 123 (Smith Ridge Road) and Route 106 (Silvermine Road) between the New Canaan Field Club and 183 Smith Ridge Road. The project is approximately 200 feet in length as measured along Route 123.

The majority of the work is to be completed within a 21 consecutive calendar day window with a traffic detour in which Route 123 will be closed and vehicular traffic detoured onto town roads. However, due to noise restrictions, the Contractor may only perform construction activities from 7:00 AM to 7:00 PM for the entire project.  The detour is currently scheduled to start April 12, 2021 and will end May 2, 2021.
