3. Wilson Road expansion

The expansion of Wilson Road between just north of Beltway 8 and Atascocita Road will widen the road from two and three lanes to four and include traffic signalization at Green Road. The project entered the design phase in September. The expansion will be bid in early 2017.

Timeline: TBD Cost: $10.2 million Funding sources: Harris County Precinct 4

4. Cypresswood Drive improvements

A joint participation project between the TxDot and Harris County, the project aims to mitigate congestion and improve air quality as well as provide traffic signal improvements between Holzwarth Road and FM 1960. Proposed improvements include traffic signal system installations, median modifications and turn-lane changes. Harris County will fund the corridor design efforts for Cypresswood Drive and fund 20 percent of the construction costs.

How it works

Why are we paying tolls after the road’s construction is paid for?

Tolls pay for more than just building new 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.

Regularly scheduled increases of toll rates also help pay for future projects.

Gas taxes and vehicle registration fees do not fund the toll roads. That revenue is used to fund nontolled 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.
