MBTA to Close Red Line Service and Replace with Shuttle Buses at All Cambridge Stations July 21–30, 2026

There will be significant planned MBTA Red Line closures taking place in Cambridge and the greater Boston area. The following commuter and traffic impacts will take place from Tuesday, July 21 through Thursday, July 30, 2026. Affected stations are Alewife, Davis, Porter, Harvard, Central, Kendall/MIT, Charles/MGH, and Park Street.

Red Line service will be suspended between Alewife and Park Street for 10 consecutive days. Free and accessible shuttle buses will replace and make all stops between Alewife and Park Street.

The City of Cambridge expects heavy travel delays throughout the region during this time. Residents, workers, and visitors should plan ahead, consider using different travel options if possible, and give themselves extra time to get where they need to go.

The MBTA is using this closure to complete important upgrades, including track work, signal improvements, and other repairs that help keep the Red Line reliable for the long term. According to the MBTA, these kinds of regular upgrades are necessary to maintain the system for future riders.
