The replacement of Riverview Road bridge in the Gaylordsville section of New Milford begins Monday, April 21.
Preliminary work will be completed by May 5, with Riverview Road closed at that time until mid-November.
The detour route will be over South Kent Road, to Long Mountain Road to Brown’s Forge Road to Station Road.
The old bridge will be completely removed and a new, wider bridge installed. The construction work will be done by Black & Water Construction, of Unionville. The replacement is being paid for by a bonding package passed in 2012.
