Oversize/Overweight Pilot Program

Programs

TxDOT will launch a pilot program for Oversize/Overweight (OS/OW) trucks on SH 130 (Segments 1–6) and SH 45 Southeast (SH 45SE) beginning November 12, 2026. The program is intended to enhance mobility and address growing transportation demands in Central Texas by allowing select vehicles operating under qualifying oversize/overweight state permits to use these toll roads east of I-35.

Eligible vehicles will be permitted to travel on SH 130 and SH 45SE, providing an alternative route around traffic congestion and construction along I-35. While TxDOT’s I-35 expansion projects will deliver long-term mobility benefits for the region, ongoing construction continues to impact commuters and travelers. This pilot program is a step toward diverting truck traffic from I-35 and reducing traffic bottlenecks.

Frequently asked questions (FAQs)

Learn specifics regarding the OS/OW Pilot Program by reading through the FAQs below.

TxDOT launched a pilot program for oversize/overweight vehicles to enhance mobility and address growing transportation demands in Central Texas. While in effect, vehicles operating under certain OS/OW state permits can travel on the SH 130 and SH 45SE toll roads, bypassing traffic and construction along I-35.

Though still considered a pilot program, TxDOT will evaluate it after six months and continue monitoring traffic impacts to determine whether to extend the program or make any modifications. Drivers will be notified of any changes through the same communication channels used to announce the pilot program.

All drivers with an OS/OW permit should check the permit limitations on their permit and the Texas Department of Motor Vehicles (TxDMV) website. OS/OW vehicles are limited to 16 ft. max in width and height, and no superheavy.

Drivers can access only the main lanes of SH 130 Segments 1–4 and SH 45SE; they are not allowed access via the entrance/exit ramps or direct connectors to SH 45 North (SH 45N), U.S. 290, or SH 71.

Access via other ramps along Segments 1–4 of SH 130 (between I-35 and U.S. 183) and SH 45SE is prohibited.

No, OS/OW vehicles are allowed to travel only on SH 130 and SH 45SE. They may not travel on any of the other Austin-area toll roads managed by TxDOT or the Central Texas Regional Mobility Authority (CTRMA).

Yes. A curfew is in place for vehicles 12' max width and/or 95' max length in the Austin area restricting travel during the hours of 7-9 a.m. and 4-6 p.m., Monday through Friday. OS/OW trucks are only permitted to use the roadways outside of the listed curfew hours.

You should contact a mobile mechanic to assist with your maintenance issue. If you are traveling on SH 130 between Georgetown and SH 45SE in Buda, you may contact Courtesy Patrol at 512-874-9102 for roadside safety assistance. If you are traveling on SH 130 from U.S. 183 to I-10 in Seguin you may contact SH 130 Concession Company Roadside Assistance at 877-741-3089.

A toll tag is not required, but it is recommended because vehicles with a toll tag receive discounted rates. Visit the Austin area toll roads page to compare toll rates.

No. You do not need to provide toll tag information to TxDMV or permit information to the tolling agency. Law enforcement agencies will monitor OS/OW traffic on SH 130 and SH 45SE to ensure compliance with the requirements on the permit.

A TxDOT TxTag, Harris County Toll Road Authority (HCTRA) EZ TAG, North Texas Tollway Authority (NTTA) TollTag, Kansas Turnpike Authority KTAG, Florida SunPass, Colorado ExpressToll, Oklahoma Turnpike Authority PikePass, or Cameron County Regional Mobility Authority (CCRMA) Fuego Tag can be used to pay tolls on these roadways.

OS/OW vehicles pay tolls the same way as other vehicles. After driving on SH 130 or SH 45SE, customers without an accepted toll tag can pay online at www.hctra.org by searching for their license plate number, call 281-873-EASY (3279), or pay in person at an EZ TAG store. Customers who do not pay will be mailed an invoice with payment instructions. Unpaid invoices may result in fines and enforcement action.

It depends on the segment. SH 130 Segments 1–4 do not charge higher toll rates for OS/OW vehicles. On Segments 5 & 6, operated by SH 130 Concession Company, permitted OS/OW vehicles are classified as Class F and are charged a higher rate than standard commercial trucks. Using an electronic tag, such as TxTag, EZ TAG, or TollTag, can help reduce costs because tag rates are lower than Pay By Mail rates.
