After reviewing and analyzing multiple potential options, the two advancing alternatives are the Modern Crossover Interchange and Naugatuck River Shift. Both alternatives aim to improve safety and mobility on I-84 and Route 8, as well as improve multimodal connections within the surrounding roadway network. In both alternatives, the I-84 and Route 8 structures would be unstacked and reconstructed with an expected lifespan of over 75 years. “The Mixmaster was once a modern engineering marvel but today, it no longer meets the needs of travelers and the greater-Waterbury community. We’re excited to move this plan forward, which was based on what we heard directly from residents and businesses. This transformative initiative will change how people safely and conveniently travel through and around Waterbury,” said Connecticut Department of Transportation Commissioner Garrett Eucalitto. “Progress takes patience, and while this work will take decades to fully complete, we are committed to improving lives through transportation by implementing, and completing, certain projects within the next five years.” This plan originated through the New Mix Planning and Environmental Linkages (PEL) Study.
