Planning continued in 2025 for the Red-Blue Connector, a half-mile subway extension that would connect the Blue Line to the Red Line at Charles/MGH in the West End. The long-delayed project would dramatically improve transit access for West End residents and the thousands of commuters who travel to MGH daily.
State transportation officials say engineering studies are ongoing, but funding and construction timelines remain uncertain. West End residents and hospital workers have long advocated for the connector, calling it essential for reducing congestion and improving accessibility.
