First, any business that elects to be served by the toll way will have to decide that the additional cost of that businesses' choice of using the toll way must remain competitive with the same goods or services that does not have toll expenses. This decision is strictly up to the business. There is no imposition on the taxpayer to pay for any portion of the toll costs. If the additional costs renders the business non-competitive, the business made a bad decision.
Secondly, the option to pay more for goods and services of products supplied by the toll way is strictly up to the citizen. If the product or service is a little better, the citizen may pay more. On the other hand, they may not. There is absolutely no imposition on the taxpayer. If the citizen opts to pay a premium, fine. If not, that's fine, too.
I have a friend that needed to relocate his distribution business. He looked at Bush Toll Way. He felt the toll way made him less competitive. He signed a lease somewhere else. That's the American way.
