Rethinking The Turnpike Allston Interchange

Could the Allston I-90 Interchange Improvement project create a more accessible Charles River for pedestrians, bicycles and recreation?

We speak with two advocates who are asking for more green space at the point where I-90, the train tracks and Soldiers Field Road squeeze together between Boston University and the river bank — "the throat."
