Currently, SH 550 is the first and only toll road in Cameron County, Texas. SH 550 is located in Brownsville, Texas and connects drivers from I-69E to the Port of Brownsville directly. The toll road features cashless gantries, overpasses, and exit ramps. All vehicles can drive on SH 550 with or without a TxTag or PToll account. Vehicle registration information is received when a vehicle passes through a cashless gantry. Our back office will then mail you a bill using the address that is registered to your vehicle. A processing fee of $1.00 is applied to every bill mailed to the address. Failure to pay toll bills can result in a misdemeanor.

Toll Bills can now be paid over the internet at your convenience. There is a slightly higher rate for Pay By Mail due to its processing fees, and you may receive bills from different tolling authorities if travelled through different toll roads. Pay By Mail customers are billed using the address on their vehicle registration information captured when traveling through toll roads. It is highly important that your information is always kept up to date to ensure that bills are sent to the correct address. Any failure to pay a Toll Bill can result in court fines and additional fees. It is very important that as a Texas driver you understand that if you lease or loan your vehicle out, you are responsible under Texas law for any tolls incurred by the driver.
