No single entity owns the toll roads in Texas. Ownership is split among the Texas Department of Transportation, two regional mobility authorities, the Harris County Toll Road Authority, the North Texas Tollway Authority, and a small number of private companies operating under long-term state contracts. Which entity owns the road you drive on decides what rate you pay, which transponder account the money flows into, and which rules apply when a bill goes unpaid.
TxDOT-Owned Toll Roads
The Texas Department of Transportation owns and operates roughly 263 centerline miles of toll roads and managed lanes across the Austin, Houston, and Dallas-Fort Worth regions.1Texas Department of Transportation. Toll Roads in Texas These are state highways, legally part of the primary highway system, built under Texas Transportation Code Chapter 228.
The TxDOT network includes:
- The Central Texas Turnpike System: Loop 1, SH 45 North, SH 45 Southeast, and SH 130 Segments 1 through 4.
- In the Houston area: the SH 99 Grand Parkway System, SH 249 Segment 1, and the SH 288 Managed Lanes.
- In Dallas-Fort Worth: the TEXpress Lanes.
Collection is fully electronic. There are no cash booths on TxDOT routes. The state issues TxTag, a windshield sticker tied to a prepaid account that is charged as you pass each gantry.1Texas Department of Transportation.

Regional Mobility Authorities
Regional mobility authorities are independent political subdivisions created at the request of one or more counties and authorized by the Texas Transportation Commission under Chapter 370 of the Transportation Code. An RMA owns its roads outright. It does not hand them off to TxDOT or to a county. Each RMA has its own board, sets its own toll rates, and chooses its own projects.
Two active RMAs cover very different corners of the state:
- The Central Texas Regional Mobility Authority, in the Austin area, owns 183A Toll, 290 Toll, 71 Toll, 183 Toll, SH 45SW, and the MoPac Express Lanes.1Texas Department of Transportation. Toll Roads in Texas
- The North East Texas Regional Mobility Authority, in the Tyler area, owns Loop 49.1Texas Department of Transportation. Toll Roads in Texas
Because RMAs are self-sustaining through tolls and bonds, the money collected on CTRMA roads stays in the Austin region, and NET RMA revenue stays in East Texas. It does not flow to the state’s general transportation fund.
Harris County Toll Road Authority
The Harris County Toll Road Authority is not a separate political body. It is a department inside Harris County government, operating under Chapter 284 of the Transportation Code, which authorizes certain counties to build and operate toll projects. HCTRA’s roads, including the Hardy Toll Road, the Sam Houston Tollway, and portions of the Westpark Tollway, are owned directly by the county. The Harris County Commissioners Court has final say on toll rates and expansion.
HCTRA issues the EZ TAG, which works on its own roads and across the rest of the Texas toll network.1Texas Department of Transportation. Toll Roads in Texas Toll revenue goes back into the Harris County transportation budget, and elected county officials have direct oversight rather than an appointed independent board.
North Texas Tollway Authority
The North Texas Tollway Authority is a multi-county political subdivision governed by Chapter 366 of the Transportation Code. Unlike HCTRA, which answers to one commissioners court, NTTA operates across multiple counties in the Dallas-Fort Worth metroplex. Its network includes five toll roads, two bridges, and one tunnel:2North Texas Tollway Authority. Roads and Projects
- Dallas North Tollway
- President George Bush Turnpike
- Sam Rayburn Tollway
- 360 Tollway
- Chisholm Trail Parkway
- Lewisville Lake Toll Bridge
- Mountain Creek Lake Bridge
- Addison Airport Toll Tunnel
NTTA issues the TollTag and operates as a financially independent entity. It carries its own debt, sets rates through its board, and reinvests revenue into its own network. It functions much like a self-contained business, paying down construction bonds and funding maintenance without drawing from the state general fund or county tax rolls.
Privately Operated Toll Roads
A small number of Texas toll roads are built and operated by private companies under long-term contracts called Comprehensive Development Agreements, authorized by Chapter 223 of the Transportation Code. Under a CDA, the state typically keeps ownership of the land and right-of-way, and the private partner designs, builds, finances, and operates the road in exchange for the right to collect tolls over several decades.
Two projects show how this works in practice:
- SH 130 Segments 5 and 6, running between Austin and San Antonio, was built under a 50-year concession. Traffic came in below projections, the SH 130 Concession Company filed for Chapter 11 bankruptcy in March 2016, and Cintra relinquished its ownership stake to creditors later that year while continuing to run day-to-day operations.3Texas Department of Transportation. SH 130 Segments 5 and 6 Executed Agreements4Federal Highway Administration. Project Profile: SH 130 Segments 5-6
- North Tarrant Express, along I-820 and SH 121/183 in the Fort Worth area, operates under a 52-year concession held by a consortium led by Cintra and Meridiam Infrastructure.5Federal Highway Administration. Project Profile: North Tarrant Express
The SH 130 bankruptcy shows the model’s real limit. When revenue falls short, the private company absorbs the loss rather than taxpayers. The road itself does not close. Concession contracts include government step-in rights if the operator fails to maintain the road or meet its obligations, and the state retains ownership of the underlying infrastructure regardless of what happens to the company running it.
The Texas Legislature allowed the authority to enter into new CDAs to expire in 2017. Existing agreements continue under their original terms, but the state has stopped creating new private concessions for the time being.
One Tag Covers Every System
With so many separate owners, you might expect to need a different transponder for each one. You don’t. The three main Texas toll tags, TxTag from TxDOT, EZ TAG from HCTRA, and TollTag from NTTA, are interoperable. Any one of them works on virtually every tolled road in Texas, regardless of which entity owns it.1Texas Department of Transportation. Toll Roads in Texas Interoperability has been in place for nearly 15 years.
Texas tags also reach beyond state lines through the Central United States Interoperability program, which links toll systems in Texas, Kansas, Oklahoma, and certain roads in Colorado and Florida. A single active account with any participating agency covers all participating roads.1Texas Department of Transportation. Toll Roads in Texas Keep only one tag mounted on your vehicle at a time to avoid being double-charged.
What Happens If You Don’t Pay
Enforcement varies by owner, but the pattern is consistent. If you pass a gantry without a transponder, cameras photograph the plate and the owning authority mails an invoice at a higher rate than transponder users pay. Ignore it, and administrative fees stack up. Those fees generally range from a few dollars to $50 per violation depending on the authority and how long the bill goes unpaid.
Texas law defines a habitual violator as someone whose vehicle has accumulated 100 or more unpaid tolls after receiving two notices of nonpayment. At that point, the toll authority can ask the county to block the vehicle’s registration renewal. You cannot renew until the outstanding tolls and fees are resolved, which eventually makes the vehicle illegal to drive on any road, not just toll roads.
If debts stay unpaid long enough, toll authorities can also send accounts to third-party collection agencies. Once that happens, the debt may appear on your credit report and can stay there for up to seven years from the date of the original missed payment. Paying the balance updates the account status but does not remove the record early.
