The Texas Department of Transportation (TxDOT) receives its funding from taxpayers, through taxes on gasoline and bond money that leverage those gas tax dollars. Over the past few years, gas tax revenue has decreased due to improved fuel efficiency in automobiles and motorists driving less frequently for a variety of reasons. The gas tax rate per gallon has not increased for nearly 20 years and does not fluctuate with the unpredictable price of gas.
The North Central Texas Council of Governments' Regional Transportation Council (RTC) determines the prioritization and funding of transportation projects in North Texas. In our growing North Texas region, transportation needs are significantly greater than the available gas-tax dollars. Simply put, the sole source of revenue to pay for transportation projects in Texas has decreased, while both the population and need for improved roadways have increased.
In response, RTC developed the region's managed toll lane policy. The region expects LBJIG to maintain a reliable level of service for motorists traveling at 50 mph. Because having fewer cars on the roadway improves mobility throughout the project corridor, the region also has developed a discount for mass transit and peak period carpoolers as an incentive.
Even with the addition of the new TEXpress Lanes, drivers will continue to have the choice to drive at no cost on the completely rebuilt main lanes and continuous frontage roads.
