Construction began during the summer of 2021 on a new station entrance/headhouse to Courthouse Silver Line station. This new headhouse includes a new stair, elevator, and escalator on Seaport Boulevard in front of District Hall. The site perimeter will require pedestrian and bicycle detours into a portion of Seaport Boulevard. Construction is anticipated to be complete in late 2025 and result in a new accessible entrance to the Silver Line in the heart of the Seaport neighborhood.

The Congress Street in Fort Point reconstruction project is actively upgrading Congress Street, Sleeper Street, and A Street in Boston to improve neighborhood safety, walkability, and bike connectivity. Sleeper St has permanently converted to a one way street, running from Seaport Blvd towards Congress St. Construction typically operates from 7:00 AM to 3:00 PM, Monday through Friday. Temporary parking restrictions have been put in place during construction.
