Route 2 Rotary Replacement Project

planned

Massachusetts Department of Transportation (MassDOT) is considering replacing the Route 2 rotary in Concord, Massachusetts, where Route 2 meets Commonwealth Avenue, Elm Street, and Barretts Mill Road. The project aims to ease congestion and improve traffic flow by potentially replacing the rotary with a bridge-based interchange. Four design options are under consideration: diamond interchange, partial cloverleaf, diverging diamond interchange, and an at-grade intersection without a bridge. The project is in the planning and public consultation phase, with public feedback to be gathered in summer 2026 and a design decision expected in fall 2026. Construction contractor hiring could start in early 2031.
