[edit] Current system status
The TxTag brand name is used on the following highways:
- Operated by TxDOT:
- the Central Texas Turnpike System, which encompasses Highway 130, bypassing Austin to the east, Highway 45, an east-west road roughly straddling the Austin-Round Rock boundary, and the northern portion of Loop 1 (Mopac) on Austin's north side
- Highway 121 through Lewisville
[edit] Future expansion
- Central Texas Regional Mobility Authority [1], which is constructing Highway 183-A as a toll bypass of US 183 through Leander, and is planning several other toll road projects throughout the Austin metropolitan area
- North East Texas Regional Mobility Authority [2], which is constructing the Loop 49 bypass of Tyler
[edit] Interoperability
- EZ TAG, operated by Harris County Toll Road Authority and Fort Bend County Toll Road Authority
- TollTag, operated by North Texas Tollway Authority
Since 2003, HCTRA's EZ TAG and NTTA's TollTag have been mostly interoperable, with the exception of Dallas/Fort Worth International Airport and Dallas Love Field airport parking, where NTTA's Tolltag is the only ETC system recognized. TxTag transponders are accepted at all designated lanes on HCTRA and NTTA roadways. EZ TAG and TollTag are accepted at all TxTag locations. TxTag transponders are currently not accepted at toll facilities at the Mexican border, nor are they honored by any toll authority outside of Texas.
[edit] Technology
TxTag uses TransCore eGo Plus flexible sticker-type transponders for most vehicles. The stickers are mounted on the inside of the vehicle at the top center of the windshield.
