The state Department of Transportation has announced a minor change in the Route 133 bridge closure happening this weekend.  The road connecting Bridgewater and Brookfield over the Housatonic River was supposed to be closed to traffic starting at 10pm Friday, but that's been moved up.  The detour will start at 8 o'clock Friday night and last through 5am on Monday morning.  A second closure date has been set for 10pm on June 26th through 5am on the 28th.  The $9.86 million bridge rehabilitation project is scheduled to be completed by July 10th.  The 851-foot bridge was built in 1955, and determined to be deficient in 2015.  Traffic may be detoured to Route 67, Route 7/U.S. 202 and Route 25 during the closures.
