The Allston I-90 Interchange Improvement Project

The stretch of the Mass. Pike that runs through Allston is getting a makeover, and the state is projecting a total bill of about $1 billion. The project will include new interstate exits, facilities for bicycles and pedestrians, space for commuter rail layover, and a brand new commuter rail stop, West Station. The state has said that West Station will open by 2040, but community members and public transportation advocates say the new station should open much sooner than that.
