But, because the adjoining land is relatively high price, you get far less capacity for the same amount of dollars.
Plus, in 30 years you have a road that can't be expanded unless you buy more of that relatively expensive adjoining land.
With as strong a level of opposition as exists to the TTC, building a traditional Interstate is a more practical option at this time. The Texas DOT does have funding issues, and bypasses of places like Victoria and Lufkin may have to be tolled, as well as the Grand Parkway. It may also be time to either increase the gasoline tax or dedicate the tax entirely to road construction. The best is the enemy of the good at times. The TTC will provide better service, but it is not politically feasible.
