Reconstruction of Aquarium Station

Abstract

This paper discusses the analysis and design for the reconstruction of the Massachusetts Bay Transit Authority (MBTA) Aquarium subway station in downtown Boston. This unusual design includes rebuilding and extension of the Blue Line rapid transit station, and construction of the new I-93 Central Artery highway tunnel directly above it. All construction work will be performed while the existing I-93 viaduct remains in service overhead, the MBTA subway operations are ongoing, and surface street vehicular and pedestrian traffic is maintained.
