The first phase of a planned Route 82 reconstruction would create three roundabouts from the Asylum Street intersection to Dunham Street and install a median divider along West Main Street, with construction slated to start in 2025. A second phase and three more roundabouts are planned for construction in 2026, state Department of Transportation project officials told about 50 Norwich residents, city leaders and business owners at an informational meeting Thursday in the Kelly Middle School auditorium. DOT officials said Phase 1 is estimated to cost $20 million, and Phase 2 is pegged at $25 million. Michael Laurice, project engineer, described Phase 1 as having three single-lane roundabouts and one temporary red light at the Dunham Street intersection. The roundabouts would have an inner circle area to accommodate large trucks, buses and firetrucks. Construction of Phase 1 is planned to start in spring of 2025 and be completed in fall of 2026. Phase 2 would begin in 2027.
