(Providence, RI) -- The Rhode Island Department of Transportation is announcing a new traffic pattern for Interstate 95 in Providence due to work on the Blackstone Street Bridge replacement project. Officials say the divided highway configuration on I-95 north and south will go up near Exit 19 in the last week of June and last for about three months. Traffic lanes will be separated by a barrier, and through-traffic will need to pass on either side of the lane split. RIDOT says this will be the same scenario that was used for Route 95 work last summer, and that motorists should not stop or switch lanes.
