Another wave of partial Green Line shutdowns start Tuesday to allow work on slow zones, according to the MBTA.
Shuttle buses will replace services between Copley and Babcock Street on the B branch, Copley and Cleveland Circle on the C branch and Copley and Brookline Hills on the D branch.
Service will be suspended all day from start to end of service for 18 days, the MBTA said. Riders will be able to use the Orange Line to get to and from downtown.
