Tarrant County will continue to wield its influence in statewide transportation issues.Gov. Rick Perry has appointed Arlington businessman Victor Vandergriff to the Texas Transportation Commission, the five-member body that oversees the Transportation Department. Vandergriff will serve a six-year term that ends in 2019.He replaces Bill Meadows, a former Fort Worth councilman who has served on the commission since 2008. Meadows' term expired in February, but he has remained on the board until a replacement could be found, as is common practice.Vandergriff's appointment is subject to state Senate confirmation, so the switch may not occur until April.Perry also announced Tuesday that he will reappoint commission member Jeff Austin III of Tyler.Vandergriff recently stepped down from a long tenure on the North Texas Tollway Authority board amid rumors that he would run for Arlington mayor -- a position he opted not to pursue after Mayor Robert Cluck decided to seek a sixth term.Vandergriff also serves as chairman of the Texas Department of Motor Vehicles, but he said he will resign if confirmed for the Transportation Commission. State law won't allow him to serve on two state agency boards.At the tollway authority, Vandergriff was instrumental in many key projects, including the planned extension of Texas 360 from Arlington to Mansfield."I haven't served on the Transportation Commission, so I don't pretend to know the ins and outs, but I am certainly familiar with the process and working with the commission for so many years," Vandergriff said."In 51/2 years with NTTA, we did a lot of projects together. I don't believe I have that steep of a learning curve as a lot of people."
