The Trans-Texas Corridor (TTC) is a proposed multi-use, statewide network of transportation routes in Texas that will incorporate existing and new highways, railways and utility right-of-ways. Specific routes for the TTC have not been determined.

As envisioned, each route will include:

• separate lanes for passenger vehicles and large trucks
• freight railways
• high-speed commuter railways
• infrastructure for utilities including water lines, oil and gas pipelines, and transmission lines for electricity, broadband and other telecommunications services

Plans call for the TTC to be completed in phases over the next 50 years with routes prioritized according to Texas’ transportation needs. TxDOT will oversee planning, construction and ongoing maintenance, although private vendors will be responsible for much of the daily operations.
