It doesn't help when goods have to be shipped using the Turnpike or businesses have to use it between job sites. The Philly area also has significant commuter traffic on the Turnpike. Traveling across state by car to visit family is costing me well over $100 round trip now.
You have an excellent point.
I think the powers-that-be in the Pennsylvania legislature are so would up in getting large amounts of subsidy dollars to SEPTA and the Port Authority of Allegheny County (and the smaller Pennsylvania transit operators) that they lose sight of the human impact of these jumbo-sized tolls on people that live inside and outside Pennsylvania.
And if all that money was going to things like Turnpike widenings and repair and rehabilitation of the PTC's many tunnels, it might be less painful. But pouring it down the black hole of transit subsidies means most Turnpike patrons never see the impact of that money.
In a fictional world the subsidies from Pennsylvania Turnpike customers would end and the cost of subsidizing transit would be shifted to higher taxes on motor fuels in the counties served by those transit agencies. Of course, even if that were happen today, the bonds sold by the PTC to make those black hole payments would still be on the books, and they will take decades to amortize down to zero, so tolls on Turnpike patrons are not going to be lower anytime soon.
