MBTA 'Resilience Roadmap' plans for climate change's impacts on transit infrastructure

The Massachusetts Bay Transportation Authority (MBTA) has released a 'Resilience Roadmap' to safeguard its infrastructure against the impacts of climate change. The agency's tunnels and power systems are considered most vulnerable to extreme weather. The plan highlights issues such as tunnel overheating, drainage and flooding problems, and potential loss of access to ferry terminals. To mitigate these risks, the MBTA will invest in its power system, protect tunnels and stations from flooding, reduce heat exposure for riders and employees, and upgrade train tracks and facilities. The agency has identified 30 new strategies, with three-quarters recommended for implementation within the next five years. These measures include installing flood-defending doors, providing more shade at bus stops, and upgrading pump rooms to remove water in case of flooding.
