How it works: Why are we paying tolls after toll road construction is paid for?

Tolls pay for more than just building toll roads. Though tolls do go toward repaying the bonds sold to fund constructing new roads, they also pay for operating and maintaining the existing roadways and funding expansions and improvements.

Essentially, a toll road is never completely paid for.

The state’s population is projected to increase to more than 30 million people by 2020, according to the Texas Department of State Health Services. As the population increases, toll roads may undergo improvement projects to accommodate for the increased traffic congestion in the area.

Regularly scheduled increases of toll rates also help pay for future projects. Toll rates are adjusted every odd numbered year.

Gas taxes and vehicle registration fees do not fund the toll roads. That revenue is used to fund non-tolled projects by the Texas Department of Transportation. Toll roads, on the other hand, are largely funded through the sale of bonds that are repaid through tolls.
