On Aug. 1, crews will begin blasting ledge along I-95 at Exit 74 in East Lyme to make room for another northbound travel lane as part of the $148 million rebuild at Route 161. The interstate will be closed in both directions for 15 minutes twice a day between 9 a.m. and 1:30 p.m., Monday through Thursday, Connecticut Department of Transportation announced. The closures will continue for 6-8 weeks. DOT spokesman Josh Morgan said it’s not possible to give a narrower range of time for the blasting because the timing of each round of blasting depends on moment-to-moment conditions. Northbound drivers will take Exit 74, continue on Route 161 north which turns into Route 1, turn left onto Cross Road, left onto Waterford Parkway, and enter back on to I-95 northbound at Exit 75.
The project will flatten the grade along I-95, replace the I-95 bridge over Route 161, create new on- and off-ramps at Exit 74, and add additional lanes between exits 74 and 75. Construction began in April, and is expected to be completed in Spring 2027. The Department of Transportation awarded the $148 million project to Manafort Brothers as the lead contractor.
