From May 6 to May 17, ramps will be closed Monday through Friday between 9 p.m. and 6 a.m. as crews cut and repave several exit ramps and install temporary concrete barriers in the area, according to the Connecticut Department of Transportation. During these times, the East Main Street on-ramp to Route 15 northbound, Route 15 Exits 67 and 68 NE, and I-91 northbound Exit 16 will all be closed. In addition, the shoulder and right lanes of Route 15 between the two closed exits will be closed. The same lanes will be closed on I-91 between Exits 16 and 17. The repaving is part of a broader, three-phase construction project at the I-91, I-691, and Route 15 interchange. The seven-year-long project is anticipated to cost between $400 million and $500 million and be completed in 2030.
