Now that the Mixmaster rehabilitation project is nearing completion, the state Department of Transportation is moving on to New Mix, a plan to look ahead to what the interchange of Interstate 84 and Route 8 will be like as much as 50 years from now. And removing the long-closed Exit 21 exit ramp on I-84 eastbound will be among the first projects on the list. To that end, a public meeting will be held Oct. 25 to discuss the removal of the exit ramp, which will include extending an auxiliary lane near Exit 22. The Oct. 25 meeting will be held from 6 to 8 p.m. at Maloney Magnet School, 233 S. Elm St., Waterbury. The first half hour will be an informal open house so the public can speak one on one with DOT project staff.
