South Boston Waterfront Transportation Center
New Construction


The South Boston Waterfront Transportation Center (SBWTC) is a multifaceted project for the Massachusetts Port Authority (Massport) to create a unique parking garage that aims to both fill a need for additional parking spaces and provide a user experience that is integrated into the urban fabric of the South Boston Waterfront District.

The project includes the design and construction of a multi-level, multi-user parking facility on a portion of Massport’s Core Block parcel in South Boston’s Seaport District. The garage is built over, and supported by, the I-90 tunnel structure built as a part of the Central Artery and Tunnel Project.
