Green Line Transformation

As part of our $8 billion, 5-year capital investment plan that began July 1, 2018, we’re modernizing and transforming the Green Line. The Green Line Transformation (GLT) program is advancing design and construction on projects that will improve safety, reliability and access for all Green Line riders and the communities we serve.
