Cracks about 60 feet long on Interstate 95 north between exits 74 and 75 closed the right lane Thursday afternoon for several hours while crews investigated the integrity of the road and worked to resolve the problem. The fissures were due to settling caused by the failure of a temporary retaining wall designed to support the highway as part of a four-year, $148 million reconstruction project, according to resident engineer Bob Obey of the GM2 project management firm. The closure was announced at 1:06 p.m. by the state Department of Transportation. The highway was reopened around 5:35 p.m. The retaining wall is being installed by contractor Manafort Brothers of Plainville to allow for the expansion of the bridge over Route 161. The soil nail wall design involves nails drilled into the earth with grout reinforcements.
