The Central Artery/Tunnel Project (CA/T), now under construction by the Massachusetts Turnpike Authority includes replacement of the existing highway structure with an eight-to-ten-lane underground expressway directly beneath the existing road, culminating at its northern limit in a 14-lane, two-bridge crossing of the Charles River, the extension of I-90 (the Massachusetts Turnpike) through a tunnel beneath South Boston and Boston Harbor to Logan Airport. The project also includes four major highway interchanges to connect the new roadways with the existing regional highway system. At Logan Airport, a new interchange will carry traffic between I-90 and Route 1A as well as onto the airport road system. In South Boston, a mostly underground interchange will carry traffic between I-90 and the fast-developing waterfront and convention center area. At the northern limit of the project, a new interchange will connect I-93 north of the Charles River to the Tobin Bridge, Storrow Drive, and the new underground highway.
