Texas — especially the DFW metroplex — has an extensive toll road network that many relocators don't expect. These roads are often the fastest commute routes, but driving them without a toll tag can get expensive quickly.

Texas has three main toll tag systems, all of which are interoperable:

DFW

Major DFW Toll Corridors

  • Dallas North Tollway (DNT): Downtown Dallas to Frisco. The most-used toll road in DFW, running through Uptown, Highland Park, Addison, Plano, and Frisco.
  • Sam Rayburn Tollway (SH 121): East-west across Lewisville, The Colony, Plano, Allen, and McKinney. Critical for north suburb commuters.
  • President George Bush Turnpike (PGBT): Major loop connecting Plano, Richardson, Garland, Mesquite, Grand Prairie, and Irving.
  • Chisholm Trail Parkway: Fort Worth south corridor.
  • LBJ Express (I-635): Managed lanes with dynamic pricing. Prices change based on traffic — can be $1 or $15+ during rush hour.
  • North Tarrant Express (NTE): I-820/SH 121/183 managed lanes in northeast Tarrant County.

TollTag vs ZipCash Pricing

Driving without a toll tag triggers ZipCash, where your license plate is photographed and a bill is mailed. ZipCash rates are 50-100% higher than TollTag rates. For example:

CorridorTollTagZipCash
DNT: Downtown to Legacy (Plano)$3.15$5.67
SH 121: Lewisville to Allen$2.80$5.04
PGBT: Full loop segment$1.50$2.70

How to Get a TollTag

  • Order online at ntta.org
  • Visit an NTTA Customer Service Center (multiple locations across DFW)
  • Minimum opening balance: $20 for one tag
  • Auto-replenish is recommended to avoid account lapses

Frequently Asked Questions

What is a TollTag and do I need one?

A TollTag is an electronic transponder from the North Texas Tollway Authority (NTTA) that automatically pays toll charges as you drive through gantries. If you use any toll roads in DFW regularly, a TollTag saves you up to 33% versus ZipCash (pay-by-mail) rates.

What happens if I drive a toll road without a TollTag?

Your license plate is photographed and you receive a ZipCash bill by mail. ZipCash rates are significantly higher than TollTag rates (often 50-100% more), plus you pay processing fees. Unpaid tolls can result in registration blocks.

Does TollTag work on all Texas toll roads?

TollTag is interoperable with TxTag (statewide) and HCTRA EZ Tag (Houston). It works on virtually all toll roads in Texas. One tag covers the entire state.

How much do Dallas toll roads cost?

Costs vary by corridor and distance. The Dallas North Tollway from downtown to Frisco costs approximately $3-6 one way with TollTag. The Sam Rayburn Tollway (SH 121) across Plano/Frisco is $2-4. Budget $50-150/month if you commute on toll roads daily.
