I-90 Allston Interchange


The overhaul of Interstate 90 at the Mass Pike Allston interchange is a once-in-a-lifetime opportunity to redistribute space using multi-modal transportation as a blueprint for development and placemaking.


A big win for the People's Pike! MassDOT has announced a final design for the I-90 Allston Interchange that includes putting the Massachusetts Turnpike at ground level in Allston and elevating a section of Soldiers Field Road along the Charles River onto a new viaduct above the highway. These changes will free up land for a new train station and dozens of acres of new development by Harvard University, as well as create a wider band of green space along the river. Read State Secretary of Transportation Stephanie Pollack's memo on her decision here

In the original plan, the state had planned to keep the highway on a viaduct but agreed to consider other options at the insistence of neighbors and advocates who preferred it be rebuilt at ground level. 

Stay tuned for updates as we continue to work with our partners and the state to push for West Station and enhanced ground level connections for people walking and biking.

  • When the I-90 interchange was built in the 1960's, construction focused on moving motor vehicle traffic and not much else.
  • Ridership on MBTA's Worcester/Framingham Commuter Line (paralleling the I-90 artery) has jumped from 600 to more than 16,000 people daily. During peak hours, there are now as many people commuting by train as there are in cars on I-90. This demand demonstrates the need to look at the project as much more than a simple highway reconstruction.

"The Pike straightening isn't a highway construction project. It's an economic development project...It is the first step that's needed to unlock 140 acres of surrounding land for new development."

  • The I-90 Allston viaduct is nearing the end of its useful lifespan and must be replaced to prevent the bridge from becoming structurally deficient. 
  • The project presents an opportunity to dramatically reduce the footprint of the existing Allston Interchange toll plaza made possible by the implementation of All Electronic Tolling (AET) in October 2016.
  • The community has stepped forward to ask the city and state to work together to create a "pike for people", unlocking opportunities for multi-modal transportation and enhancing cross-town connections to ease congestion in the urban core.

"If done right, the narrowest, nastiest, and noisiest thread of Charles River parklands could be transformed into the Allston Esplanade, the next great civic space in Boston."

- Harry Mattison | Boston Globe
