The Texas Transportation Commission has adopted an ambitious plant to built a 4,000-mile statewide network of highway/rail/utility corridors that would include truck-only toll lanes.

The Trans Texas Corridor system, unveiled by Gov. Rick Perry in January, could take 50 years to complete and will be largely privately funded.
Each corridor will be 1,000 feet wide and include two lanes for trucks in each direction and three lanes for passenger vehicles in each direction (all paid for with tolls), plus six rail lines for commuters and freight, and a 200-foot-wide utility zone. They largely circumnavigate the state’s biggest cities.
While the American Trucking Associations opposes truck-only toll lanes if they are mandatory, the Texas plan would not force truckers to use the corridors. ATA spokesman Darrin Roth told the Austin American Statesman that “in accidents involving a car and a truck, in 70 percent of the time … the accident begins with the action of the car. So getting the cars out of the way of our trucks would certainly make sense to us.”
The first four “priority” corridors will parallel or incorporate parts of Interstates 35, 37, 10 and 45, as well as the proposed I-69 routes designed to carry traffic from Mexico.
