Absolutely. 100% agree.
But this massive development, with those new 12-14 story buildings, would most certainly result in additional car/truck congestion in this bottleneck. Simply wishing that that amount of additional development won't further choke it isn't reality. Creative solutions (underpasses?, pedestrian bridges? relocating the Chestnut Hill Green Line station?, elevated monorail down Rte 9? etc.) would need to be employed. It's already a traffic chokepoint, adding this new massive development would be like throwing gasoline on a fire, without transpo changes. Given the obvious effects of this development, I'm all ears to hear the solutions.
