Amtrak Advances B Tunnel Replacement with New Construction Initiatives
Amtrak is advancing its B&P Tunnel Replacement Program, a significant infrastructure project aimed at improving rail service along the Northeast Corridor between Washington, D.C., and Baltimore. The project involves the replacement of the 153-year-old B&P Tunnel with the new Frederick Douglass Tunnel, expected to open in 2036. Amtrak, in collaboration with the Federal Railroad Administration (FRA), Maryland, and other partners, is undertaking major construction activities, including utility relocations and the replacement of the Mulberry Street Bridge. The project has reached a stage where preparatory work is underway for the launch of two tunnel boring machines in 2028. Amtrak and the FRA have identified optimization opportunities to enhance the program's design, constructability, and scheduling while addressing cost pressures.
