AUSTIN, Texas (AP) Voters statewide approved all seven proposed amendments to the Texas Constitution on Nov. 3, including Proposition 7 which will pump billions of extra public dollars into roads.

Proposition 5 lets counties with fewer than 7,500 people privatize road construction and maintenance — up from the current maximum of 5,000 residents. About 70 counties qualify.

And Proposition 7 means that when sales tax revenue exceeds $28 billion per fiscal year, the next $2.5 billion would go to road construction and maintenance starting in Sept. 2017.

Then, beginning in September 2019, if tax revenue from vehicle sales and rentals exceeds $5 billion per fiscal year, 35 percent of the amount exceeding $5 billion would go to road funding.

The amendment allows the GOP-controlled Legislature to bolster transportation infrastructure strained by Texas’ booming population without raising taxes.

“Prop 7 will provide an efficient way to dedicate a portion of our sales tax revenue to build the roads that our children and grandchildren will use,” said Rep. Joe Pickett, an El Paso Democrat who chairs the House Transportation Committee. “All we are doing is taking the success of the Texas economy and dedicating a portion of it to transportation.”
