December 9, 2012 – As the next Legislature grapples with ways to fund Texas transportation projects, top lawmakers acknowledge that failing to secure a long-term solution is no longer an option. Beyond 2014, the Texas Department of Transportation’s $10 billion annual budget is projected to cover only maintenance, , leaving no cash for expansion or construction. And Texas’ population — and transportation needs — will continue to grow. The chairmen of the state House and Senate transportation committees say they’re welcoming ideas — including a $50-a-year increase in vehicle registration fees. But emerging as a top potential fix is a constitutional amendment to dedicate the sales tax on vehicle purchases to TxDOT.
