I-95 Bridge, Often Hit by Trucks, to be Raised in Norwalk
The state Department of Transportation is moving ahead with a $10 million project to raise an I-95 bridge that has been hit several times by trucks. DOT says it’s been struck so many times the bridge is “structurally deficient and functionally obsolete.” In 2015, one truck strike was so severe it damaged steel girders and a waterline underneath the bridge. The problem with the 60-year-old Strawberry Hill Avenue bridge is not enough clearance over I-95. Plans include increasing the clea...

RIDOT Deploys Fleet of New Bridge Washing Trucks
The Rhode Island Department of Transportation showed off its new fleet of six custom-built tanker trucks May 19 and May 20; trucks outfitted with a series of high pressure water nozzles that allow a driver/operator to clean the sides and deck of a bridge in a moving operation, generally at 5 to 10 mph. On average, RIDOT said the trucks are capable of cleaning five to six bridges a day, depending on their size, and will help "significantly reduce" the time needed to close a travel lane for such m...
