Paying tolls on the State Highway 99 toll road is fast and easy. All tolls are collected electronically, so you never have to stop at a toll booth or dig for change. Simply prepay your tolls with an electronic toll account.

The following toll accounts are accepted on SH 99: TxTag, EZ TAG, and TollTag.

How does it work? As you drive under a toll gantry on the SH 99 toll road, a signal is sent to the microchip inside the electronic tag on your windshield and the toll is deducted from your prepaid account.

It's important that your license plate and credit card information are kept up to date on your toll account – and that your toll tag is installed on your windshield – to ensure that you are charged correctly.

In addition to SH 99 and other Houston-area toll roads, your TxTag, EZ TAG, or TollTag can be used to pay on toll roads in Dallas, Austin, Tyler, Laredo, and Brownsville.

Setting up a toll account is easy – online, by phone, or in person.
