Building a Better T 2020

Major construction is underway to make the T better, safer, and more reliable. We are accelerating several projects—including station, vehicle, and infrastructure improvements—that will deliver results to riders much sooner.

This accelerated work is just a piece of our full Building a Better T portfolio of projects.

Work Completed Since 2020
