The Commonwealth Avenue Carriageway Redesign Project will redesign, reconstruct and restore a critical compromised segment of the Commonwealth Avenue Carriageway from Lyons Field to the Marriott.  The project will create new  green space and  add a continuous walking and bicycle path where the roadway currently exists by rerouting vehicular traffic from north of the median to the south. Project benefits include: a) increase the overall amount of green space b) link myriad trail networks including the Charles River Path, the Riverside Greenway trail network (in development), and Weston’s planned shared use path, currently at 25% design, running along Commonwealth Ave from the Newton to Natick borders, d) increase visibility and access to the Charles River at the historic boathouse e) improve transit access in the area by upgrading bus stops.

Construction is fully funded through MassDOT's Bicycle and Pedestrian Program with $5.9 million in funding confirmed for FY2023.
