Boston Advances Major Infrastructure Projects Across Allston, Mattapan, Rail Links

Boston secured $335.4 million in federal funding for the Allston Multimodal Project to rebuild the I-90 interchange, Soldiers Field Road, and railroad lines along the Charles River waterfront. This allocation arrives alongside separate commitments that together shape near-term choices for project sequencing and resource alignment.

Allston Multimodal Project

The Allston effort targets reconstruction of the I-90 interchange, Soldiers Field Road, and railroad lines along the Charles River waterfront. City transportation documents list the $335.4 million federal award as the primary support for these elements. Decisions now center on integrating this work with adjacent rail upgrades to limit service disruptions for commuters traveling between Boston and Cambridge.

North Station Draw One Bridge Replacement

The $1.06 billion North Station Draw One Bridge Replacement project is underway to modernize the rail connection between Boston and Cambridge. It directly serves MBTA Commuter Rail and Amtrak's Downeaster. Project managers face choices on construction phasing that protect daily rail operations while completing the replacement.

Mattapan Highway and Neighborhood Work

Public Works construction on Cummins Highway in Mattapan, valued at $31.5 million, is expected to complete in 2026 with traffic improvements and new pedestrian ramps. The City of Boston also received approximately $2 million to reconnect the two long-separated sides of the Mattapan neighborhood and link them to natural resources and multimodal transportation. These Mattapan efforts require coordination with the larger capital schedule to align ramp installations and street connections.

MBTA Five-Year Capital Plan

The MBTA is executing a $9.6 billion, 5-year capital investment plan that includes renovating stations, modernizing fare systems, and upgrading bus, subway, and ferry services. This plan supplies the operational framework that the Allston, North Station and Mattapan projects must fit within. Agencies will decide how to sequence station renovations and service upgrades against the timelines of the funded highway and bridge work.

Next steps hinge on aligning the $335.4 million Allston award, the $1.06 billion bridge replacement, the $31.5 million Cummins Highway work and the $2 million Mattapan reconnection with the MBTA's $9.6 billion plan. City and state offices must determine construction order, permitting milestones and service continuity measures using the details already outlined in transportation project lists and capital documents.
