One that’s nearing completion is the interchange of Interstate 84 and Route 8 in Waterbury, known as “The Mixmaster,” which is composed of a stack of bridges. “We’re finally going to be finished with that project by the end of October,” Morgan said. “What’s going to be happening over the next five months or so will be periodic lane closures, some nighttime work, but we’re in the home stretch.” This project’s biggest construction work has just been getting underway in the last year and it will ultimately eliminate Exit 17 northbound on I-91, making it easier to get from I-91 to Route 15. “In this one we’ll have some of these traffic shifts during the daytime and then during the night, there’ll be lane closures … People are going to see a lot of barrels, a lot of the concrete barriers, a lot of equipment out there,” Morgan said. “We’re rocking and rolling out in East Lyme. That’s about a $150 million project,” Morgan said. The project to straighten the highway at Exit 74 and replace the exit and entrance ramps is expected to last until 2027.
