CAMBRIDGE (CBS) – Riders on the MBTA Red Line can expect some delays for the next four weekends if they’re headed outbound from Harvard Square.

The MBTA will be busing from Harvard to Alewife Stations on Saturdays and Sundays through December 9 while MBTA crews perform Red Line maintenance as part of the Floating Slab project.

The buses will make stops at all stations between Harvard and Alewife Stations. Normal Red Line train service will resume on Mondays.

All shuttle bus stops are handicap accessible.
