The North Texas Tollway Authority is scheduled to increase toll rates beginning July 1, as part of a scheduled biennial increase that was approved in 2009. TollTag member rates will adjust a penny per mile, from $0.1706 to $0.1801. ZipCash customers, those who do not have a TollTag account, pay 50 percent more for tolls. The tolls drivers pay on NTTA roads go toward repaying the more than $9.5 billion in bond money used to construct and maintain the roadways. Bonds also fund NTTA’s safety and service programs. Through 2022, NTTA will reinvest more than $900 million for widening, improvements and construction of its roads to relieve congestion and provide mobility throughout North Texas. NTTA continues work to improve and widen some of its toll roads, including the President George Bush Turnpike, the Dallas North Tollway and the Sam Rayburn Tollway.
