Way back in the dark ages, children, Texas had a toll road that ran between Dallas and Ft. Worth and was operated by the Texas Turnpike Authority. The Dallas-Ft. Worth Turnpike (as it was called) was supposed to be paid in full after 30 years.
30 years came and went and the TTA had no intention of abandoning its home for the previous 30 years. Until, that is, substantial pressure was brought to bear on the politicians by taxpayers who wanted to see the TTA forced to honor its promises.
Today, that road is I-30 between Dallas and Ft. Worth. The moral of the story is that toll roads, like taxes, are forever. The TTA ALMOST got by after 30 years. A 50 year contract on the TTC will virtually assure that NO ONE will know of or remember the agreements when the 50 years are up which means that it will be a foreign-owned toll road forever.
