Proposition 7, the Texas Sales and Use Tax Revenue for Transportation Amendment is on the November 3, 2015 ballot in Texas as a legislatively referred constitutional amendment. The measure, upon voter approval, would provide additional funding for the State Highway Fund.
The Houston-Galveston Area Council (H-GAC) estimates it will bring in an additional $500M to the region for 2015-2018 TIP cycle (see estimated funding chart on page 2 here.). The funds will primarily be used to “construct and maintain non-tolled roadways, purchase rights-of-way and make payments on general obligation bonds issued by the Texas Transportation Commission.”
