Business leaders are urging Texas lawmakers to pass measures to pump some money into roads.

As legislators meet today to try to approve a funding plan, those in favor of the added money came together Monday morning to plead passage. Groups calling for increased transportation funding include the Texas Association of Business, Texas Association of Manufacturers, Greater San Antonio Chamber of Commerce, Greater Austin Chamber of Commerce, Transportation Advocates of Texas and San Antonio Mobility Coalition. They say a dedicated revenue source for transportation will keep Texas the economic envy of the nation.

“This is an issue that affects every citizen who lives in this great state and those thousands new citizens that we get here every single day,” Richard Perez, president and CEO of the Greater San Antonio Chamber of Commerce, said. “It’s about mobility and it’s about investing in who we are and what we need to continue to be at the top of the economic development ladder.”

Lawmakers are looking to add about one billion dollars a year for transportation projects without new taxes or fees.

According to the Texas Department of Transportation, the proposed added money would only be about a quarter of what’s needed just to maintain roads. But TxDOT officials say it’s a good start.

One funding plan has passed the Senate. The House is taking up a slightly different version Monday afternoon.

If passed, voters would then have to ultimately approve the proposal in November 2014.
