From Friday Night at 9, until Monday Morning at 6, the construction of the new bridge over River Avenue in Fairhaven will disrupt traffic on I-195 and some other roads.  For the weekend, traffic will be reduced to one lane eastbound on I-195 and shifted to the median for demolition of the eastbound bridge.   The on-ramps from Route 18 north to I-195 east and Washburn Street to I-195 will be closed. Traffic will be detoured to Coggeshall  Street, Howland Road, Alden Road and Route 240.  There will be traffic boards on I-195 east, on Route 140 south and on Route 6 east with that information as well.   Happy driving.
