Beginning Saturday morning, October 17, 2026 at 6 am, we will begin paving our South Boston branch parking lot. The project will continue through Wednesday, October 21, 2026 at 11pm. Access to the parking lot during these days will be limited and members may find it difficult to find parking. Our full service branches in Everett and Quincy Center are available to use and we appreciate your patience as we make this important improvement for our members.
We will be towing unauthorized vehicles beginning Saturday morning October 17 at 5 am so the work crews can complete their work.
