The Trans-Texas Corridor concept was developed by state transportation planners using the following guiding principles:

• Efficient, reliable transportation is essential to public safety, economic vitality and quality of life.
• Transportation improvements in Texas must be completed faster.
• The planning and decision-making process must be open, with frequent and ongoing opportunities for public input.
• Separate lanes for cars and large trucks will improve safety and relieve congestion.
• Transportation routes for hazardous materials must avoid population centers whenever possible.
• Rail must play a more prominent role in improving mobility and safety in Texas.
• The Trans-Texas Corridor will be built in phases as transportation demands warrant.
• Government does not have all the answers to the transportation challenges facing Texas and needs the innovation of the private sector.
• Where feasible, the Trans-Texas Corridor should use existing infrastructure by aligning with existing highways, railways and utility corridors.
• Local officials should help determine how communities access the Trans-Texas Corridor.
• Trans-Texas Corridor planners must consider ways to minimize right of way needs.
• People who use the Trans-Texas Corridor must be treated as customers. State officials and contractors must work in concert with local entities to provide high-quality service to these customers.
• The Trans-Texas Corridor must be built with public/private partnerships in order to minimize costs to taxpayers.
