Boston's Infrastructure Upgrades Reflect Years of Coordinated Regional Planning
Current upgrades to rail bridges, the Mass Pike and local streets build on prior funding decisions and multi-community coordination.
How we reported this
Boston is moving forward with large-scale infrastructure work that spans multiple neighborhoods and adjacent cities.
The $1.06 billion North Station Draw One Bridge Replacement and Associated Track & Signal Upgrades project is being delivered by Skanska across Boston, Cambridge, and Somerville. The $2 billion Allston I-90 Multimodal Project is straightening the Mass Pike and reconnecting neighborhoods, with $335.4 million in federal funding secured in 2024 and construction expected to take 7 years. Public Works is completing $31.5 million in construction on Cummins Highway in Mattapan in 2026, including traffic improvements, road reconstruction, and new pedestrian ramps.
Why these projects matter now
These initiatives address long-standing needs for reliable transit links and better neighborhood connections that have shaped regional planning for years. Work in areas such as North Station and Allston targets rail and highway constraints that affect daily movement between Boston, Cambridge and Somerville. The Mattapan project focuses on local street conditions that influence access for residents and pedestrians.
Evidence from funding and timelines
The $335.4 million federal allocation for the Allston project was secured in 2024, providing a concrete measure of recent support for the $2 billion effort. The seven-year construction window outlined for that project sets expectations for the duration of major highway changes. In Mattapan, the $31.5 million Cummins Highway work is scheduled for completion during 2026, offering a nearer-term milestone for road and safety upgrades.
Looking ahead, the projects will continue according to their established schedules, with residents able to track updates through city and state transportation channels as construction phases advance.
