Yup, the only way to get toll roads built is to kill the free roads. Texas can expect that their economic growth will stagnate, as free roads become clogged, and toll roads dampen travel and thus economic activity.
Just like in France.
So you are demanding that the Feds pay 80% of the cost of building I-69? Because that is the funding that he talks about when he says "The road fairy(80-90% fed funding) has been shot."
The hottest area of Dallas for growth has been far North Dallas and Frisco, served by only one freeway-style road, the North Dallas TOLLWAY. So your theory of toll roads reducing economic activity is false. In fact it is quite the opposite, because the toll funding allows the roads to be built years or even decades before they could have been built using traditional gov't financing.
