New Proposals To Replace Waterbury Mixmaster

September 8, 2025

The state unveiled two design options for the long-term replacement of the I-84/Route 8 interchange in Waterbury, known as the Mixmaster. This once-in-a-generation project aims to improve safety, ease congestion, and support mobility for decades to come, with input from local residents and businesses shaping the plans. 

As shown in the renderings below, the proposals are called the Modern Crossover Interchange and the Naugatuck River Shift. In both scenarios, crews would unstack and rebuild the Waterbury Mixmaster into a modern, resilient structure with an expected lifespan of more than 75 years.
