The North Texas Tollway Authority this morning went live with its online list of top violators. Go here to check whether you're on the list. The Plano-based agency is hoping to capture some of the roughly $12.5 million in past-due tolls.Amber Young of Dallas holds the top spot on the list. She reportedly owes NTTA $179,596.43 for 8,366 toll violations.At a first glance, it appears there are no Fort Worth or Arlington-area vehicle owners on the list of top 100 violators. The overwhelming majority of violators live in Denton and Collin counties, as well as far north Dallas County.There is a pocket of more than 100 violators in Arlington's 76010 ZIP code, however. Those residents are very close to the new President George Bush Turnpike western extension (formerly Texas 161 in Irving and Grand Prairie).Fort Worth-area residents will become much more familiar with tolls and toll violations in the next few years, as projects such as the Chisholm Trail Parkway project open up in Tarrant and Johnson counties.Also, the North Tarrant Express and DFW Connector projects in Northeast Tarrant County include the addition of new managed toll lanes as well as rebuilt free lanes, so motorists who use those improved roads will be making a daily choice whether to pay tolls.
