Sumner Tunnel Crews Prepared for Detour Challenges, Ready to Adapt Instantly

The closure of the Sumner Tunnel in Boston for restoration work is facing its biggest test as regular work week commuters navigate the detours. Officials are urging commuters to consider alternate modes of transportation such as the free Blue Line, bus or ferry service, or discounted Commuter Rail. The restoration project is on track to be completed by August 31.
