Pioneer Institute applauds the Massachusetts Department of Transportation (Mass DOT) for its decision to move forward with an all at-grade design for the “throat” area as part of the massive $1.7 billion Allston I-90 Interchange project announced yesterday by State Secretary of Transportation Jamey Tesler. Pioneer had proposed that MassDOT should revise its Scoping Report on the I-90 Allston Multimodal Project and recommend an additional option - a modified at-grade option for the throat area - to the Federal Highway Administration.
