The Green Line Extension was built defective, and top officials knew about it

Yesterday, MBTA General Manager Phillip Eng announced that miles of track on the less than one-year-old Green Line Extension were built too narrow. They'll need significant, labor-intensive repair.

State officials said leaders at the T knew about the problems since April of 2021.

“Senior MBTA officials under the previous administration knew about issues with the Green Line Extension tracks years ago and did not disclose them to our administration or address them on their watch,” Gov. Maura Healey said in a statement.
