The North Texas Tollway Authority’s (NTTA) mission is to enhance mobility through responsible and innovative tolling solutions. As of December 11, 2010, the NTTA became the United State’s largest tolling system to convert its approximately 65 miles of toll roads, bridges and tunnels to all-electronic toll collection (all-ETC), eliminating cash collection in the lanes. All-ETC improves air quality, fuel efficiency and time savings through reduced stop-and-go traffic and idling at toll booths. It also heightens motorist and employee safety through the elimination of merging and weaving at and around toll booths. The operational savings NTTA will realize over time will be reinvested in other North Texas mobility projects.
