A historic Boston transit hub is undergoing a high-tech examination in preparation for its future. Early-stage work on Boston's $850-million South Station expansion proposal is deploying a robust level of construction-sequence modeling in hopes of minimizing major construction conflicts within a rail hub that sees more than 100,000 daily commuters.
South Station, a 110-year-old architectural icon, is Boston's busiest multimodal transportation hub and the sixth-busiest hub for Amtrak, the national passenger railroad. Gov. Deval Patrick (D) recently made the South Station expansion a priority in his $13-billion transportation plan for the state. The project is currently in planning, environmental review and preliminary design.
