Editor's note: An earlier version of this story read that the state's Department of Transportation had scheduled traffic detours on back-to-back weekends. The state has since updated local police that the traffic rerouting will take place the weekend of Aug. 11-13 and Aug. 25-27. 

An extra 17,000 cars and trucks a day will be going through Ridgefield center during two weekends in August.

The state's Department of Transportation is planning to shut down the Route 7 bridge site the weekend of Aug. 11-13 and Aug. 25-27.

"The first weekend to install the bridge abutments and the follow on weekend to install the precast deck units," ," said John Dunham, district engineer for the state Department of Transportation.

Route 7 will not be a through road — not in Branchville — and its traffic will be detoured through the village.

As a result, all the traffic on Route 7 — figured at about 17,000 vehicles a day on a Saturday and 13,000 on a Sunday, according to the state Department of Transportation — will be coming right down Main Street.

“The overall superstructure was rated as poor based upon field inspection,” Dunham said of the bridge earlier this summer. “Field inspection and engineering analysis [said] the structure was determined to be functionally obsolete and hydraulically inadequate meaning it could not pass the 100-year flood storm event.”
