BOSTON (WBZ NewsRadio) — The new green line stop coming to Union Square in Somerville will open later than scheduled.
Originally set to open in December of 2021, the Union Square branch is now set to open in March of 2022, the MBTA announced in a press conference Thursday.
MBTA general manager Steve Poftak said the delay is due in part to trouble building the traction power substations for the stop.
"There's only so many people that can fit inside that space and do productive and technically demanding work," Poftak said in a press conference. "I think that proved to be one of the challenges.

These substations are crucial to the extension project because they provide power to operate the trains. The second part of the green line extension that goes into Medford reportedly requires two of the traction power substations.
Poftak said he is confident this will be the last delay for the Union Square branch. He also said he is hopeful the Medford branch of the extension, which is supposed to open in May 2022, will open on time.
