Tolling & Access

Toll Rates 

The toll on the SH 45SW Expressway will be $1.00 for a 2-axle vehicle with a toll transponder. The SH 45SW Expressway will feature all-electronic tolling; drivers will not see any toll booths. Now that the SH 45SW toll road is opened, drivers may pay their tolls without stopping, using any of the following payment program providers:

Drivers will also be able to Pay by Mail (license plate is photographed and bill is mailed to address where vehicle is registered). The toll rate for Pay by Mail customers is $1.50. Bills are mailed every 30 days. Each bill includes a $1.00 invoice fee.

Toll rates are normally increased annually based on the rate of inflation.

SH 45SW Access

SH 45SW is a limited-access expressway. Entrances and exits to the facility will be provided at the following locations:

  • FM 1626
  • Bliss Spillar Road
  • State Loop 1 (MoPac)/SH 45 

SH 45SW Toll Road and Trucks

With the exception of trucks carrying hazardous materials, large trucks will be permitted to use the expressway. SH 45SW is not expected to carry a significant amount of truck traffic based on the low volume of truck traffic that currently utilizes SH 45 and the southern portion of MoPac.

Why is SH 45SW going to be a toll road?

The federal and state gas tax is no longer sufficient to meet all the transportation needs of a rapidly growing area like Central Texas. The gas tax hasn't been adjusted for inflation since 1993; even as highway construction and maintenance costs have increased significantly. In addition, greater vehicle fuel efficiency has impacted gas tax revenue.  Between 2015 and 2024 the Capital Area Metropolitan Planning Organization (CAMPO) estimates that the local community will receive $2.5 billion in highway funding from federal and state sources.  For comparison sake, the cost to upgrade just IH-35 through Hays, Travis and Williamson County is expected to cost as much as $4.5 billion.
