MBTA to begin Red Line slab replacement project
Written by jrood
Crews from the Massachusetts Bay Transportation Authority will begin replacement of concrete slabs along Red Line track from Harvard to Alewife. The track sits on concrete slabs that float on rubber disks, which absorb noise and vibration from trains. Years of water filtration into the tunnel has resulted in corrosion and cracking that must be addressed in order to maintain safe and reliable Red Line service. MBTA work crews will be removing and replacing corroded concrete slabs as part of a project partially funded by the American Recovery and Reinvestment Act. In addition to correcting problems with the floating slab structure, the project will involve the replacement of track and 3rd rail. Workers will also address leaks in the tunnel to prevent further deterioration.
