Allston Interchange revamp expected to cost $1B

BOSTON — A project that would completely redesign the Allston Interchange on the Mass Pike is projected to cost $1 billion, according to the Boston Globe.

The project has been in the works since 2014, as MassDOT has worked to develop a concept to replace the Allston Interchange, realign and straighten the Pike and add another Commuter rail stop.

Transportation Secretary Stephanie Pollack said the state plans to submit construction and environmental plans by the end of the month, with the hope of starting construction in 2020 and finishing the project by 2025, reports the Globe. The final price tag is estimated to be $1.2 billion.

MassDOT has the elevated viaduct near Boston University has to be replaced due to its age, and would likely bring the Pike down to ground level. The new construction will be designed to be "less intrusive" to the Allston community, and would also add bicycle and pedestrian connections in the area.
