The Texas Legislature created the Turnpike Act on June 9, 1953, thereby creating the Texas Turnpike Authority. The Texas Turnpike Authority began issuing bonds in 1955 for its second project, the first 30-mile section of the Dallas North Tollway. The original cost was $33,650,000 and started in 1966 and completed from Interstate 35E near downtown Dallas north to Royal Lane in 1968, and soon after to Interstate 635.
Toll controversy J.H. "Jack" Davis, Engineer-Manager for the Texas Turnpike Authority, stated in 1968 that "When revenue bonds for a project are finally paid off, however, the facility reverts to the state as part of its highway system, to be used free." This was supposed to happen the same way the Texas Turnpike Authority turned over the Dallas–Fort Worth Turnpike to the Highway Department in 1977 to become
I-30, which then became toll free. However, the Dallas North Tollway never became toll free and has never been turned over to the Highway Department. The North Texas Tollway Authority's web site states that "it was no longer a statewide practice to remove tolls from roadways due to a lack of state funding to maintain the roadways". While it may have been Jack Davis' unofficial intent, it was not law. The last bond payment was made January 1, 2005. The Texas Legislature created the North Texas Tollway Authority in June 1997, replacing the Texas Turnpike Authority on September 1, 1997. The Regional Tollway Authority Act, Chapter 366 of the Texas Transportation Code, is what authorizes the North Texas Tollway Authority, thereby making it a political subdivision of the State of Texas and the operator of the North Dallas Tollway. The initial segment of the tollway ran from Interstate 35E to Royal Lane along an old
St. Louis Southwestern Railway corridor. The right-of-way is generally along this segment, one of the narrowest controlled-access roads in Texas. The segment was completed in June 1968 and toll was originally 20 cents. The tollway was later extended to Briargrove Lane in 1987, to Headquarters Drive in 1994, to
SH 121 and Gaylord Parkway in 2004, and to US 380 in 2007. The extensions generally parallel
SH 289, also known as Preston Road. The "DNT Extension Phase 3," which runs from SH 121 to
U.S. Highway 380, opened in mid-2007. Current tolls vary from $0.40 to $2.15 for a car with it being more expensive closer to downtown; the lone exception is the Eldorado Pkwy. toll plaza in Frisco. The Tolltag offers a discount on these rates (tolls are $0.30 to $1.41) but requires a prepayment of $40 for up to three transponders, and after that, TollTag accounts can be reloaded at a minimum of $10. Rates increased in September 2009 and will increase every two years. All toll plazas are now equipped for electronic toll collection and main lane plazas feature
TollTag express lanes. ==Route description==
