The B&P Tunnel Replacement Program continues to make significant progress in Baltimore, with major construction activities now underway and several community-focused initiatives advancing.
We have started construction on the Tunnel Boring Machine (TBM) launch pit at the South Portal, marking a major milestone toward building the new twin-track tunnel that will replace the aging B&P Tunnel.
Key Construction Updates
South Portal: Excavation of a 60-foot-deep launch pit begins this summer, preparing for future TBM operations that will excavate the new tunnel tubes.
West Baltimore MARC Station: Construction of the relocated Lot B bus loop is scheduled to begin in October 2026. The new bus loop, ADA parking area, and West Mulberry Street railroad bridge are expected to open in October 2027.
West Mulberry Street Railroad Bridge: Reconstruction continues, with reopening anticipated in October 2027.
Lafayette Avenue Bridge: Replacement will occur in two phases and will require street closures, temporary park relocation, shuttle services, and traffic-management measures.
North Portal Ventilation Facility: Utility relocation work continues near McMechen Street to support construction of the future ventilation and emergency egress facility.
Community Engagement
Community Investment Program: The first funding cycle received strong interest, with more than 200 participants attending information sessions. Grant recipients and the Historic Preservation Grant Fund Administrator will be announced in the Fall. The next application cycle is currently planned for Spring 2027.
Preserving Baltimore’s Railroad History: We’re gathering stories about the people and legacy of the Baltimore and Potomac (B&P) Railroad for a display at the new West Baltimore MARC Station. Whether your connection comes from family history, community ties, or historical knowledge, we’d love to learn more. Please contact BPTunnel@amtrak.com with any stories or information!
Strengthening Workforce Development Efforts: As part of its commitment to workforce development, Amtrak has partnered with the Baltimore Mayor’s Office of Employment Development and the Baltimore Workforce Funders Collaborative (part of the Maryland Philanthropy Network) to prepare interested residents for construction jobs and support career pathways in the rail and construction industries, aligning these efforts with Maryland’s Raising the Bar initiative.
Historic Salvage Program Expanded: Recovered materials from historic properties affected by the project are now available to the general public, regardless of residence. Materials can be viewed and collected free of charge through August 1, 2026, at the Atlas Building in Baltimore.
Staying Connected: Residents can receive construction and traffic updates via email, community outreach channels, or text alerts. The Program Outreach Team remains available to respond to community questions and concerns. See newsletter for details.
