Actually heard a bit of sense from a 'woman on the street' interview about possibly tolling 422, a highway in the Western burbs of the urban hellhole which at one end connects up with the Schuylkill Expressway, the only urban highway entering the city from that direction. And, as she said, even if they widen 422 (a possible use of toll money), it won't matter all that much because the Schuylkill is basically 2 lanes in each direction and there isn't a practical way to widen it even if billions were available.
There's significant travel along that road which is intra-suburban, and not about connecting up to drive into the city, but my main point is that there will not be any highway improvements into Philadelphia basically ever again.
