Highways in Texas

The Dallas North Tollway (DNT or simply the Tollway) is a 32-mile (51 km) controlled-access toll road operated by the North Texas Tollway Authority (NTTA), which runs from Interstate 35E near downtown Dallas, Texas (USA), to U.S. Highway 380, near Frisco, Texas. The "DNT Extension Phase 3," which runs from State Highway 121 to U.S. Highway 380, opened on September 28, 2007.^[1]

The initial segment of the tollway ran from Interstate 35E to Interstate 635 along an old railroad corridor. The right-of-way is generally 100 feet (30 m) along this segment, one of the narrowest controlled-access roads in Texas (although the Westpark Tollway has a right of way of only 50 feet (15 m)). The segment was completed in June 1968 and toll was 50 cents. All toll plazas are equipped for electronic toll collection and main lane plazas feature TollTag express lanes.

The tollway was later extended to Briargrove Lane in 1987, to Headquarters Drive in 1994, to S.H. 121 and Gaylord Parkway in 2004, and to US 380 in 2007. The extensions generally parallel S.H. 289 (locally known as Preston Road).

Current tolls vary from $0.40 to $1.30 for a car with it being more expensive closer to downtown; the lone exception being the Eldorado Pkwy. toll plaza in Frisco. The Tolltag offers a discount on these rates (tolls are $0.30 to $1.05) 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 on September 29, 2007, the first increase since 2002. ^[2]

[edit] Introduction of the TollTag

The Dallas North Tollway was the first toll road in the United States to implement Electronic Toll Collection technology, with the introduction of the TollTag in 1989. TollTag users were originally charged $.05 extra per transaction, but by 1999 the agency moved to actively encourage TollTag use by giving tag users a discount off the cash toll rate.

In August 2007, the NTTA announced plans to phase out manned toll booths entirely by May 2010.^[3]

[edit] Future improvements/extension

This article contains information about a planned or expected future road.
It may contain information of a speculative nature and the content may change as the road's construction or completion approaches and more information becomes available.

[edit] Southern section

At the Tollway's southern end, near downtown, the agency is rebuilding the road around the main toll plaza and adding ramps at Oak Lawn Avenue. This project, started in 2006, is scheduled to take two years. On the southern sector of the tollway, the agency plans to spend about US$43 million to add an entrance and exit at Oak Lawn and rebuild most of the tollway surface from the Interstate 35E ramps to Lemmon Avenue. The tollway authority also will completely rebuild the aging toll plaza, adding a third TollTag express lane in each direction. This work coincides with major projects by the city of Dallas to rebuild part of Oak Lawn under the tollway, and by Dallas Area Rapid Transit (DART) to build a rail line along nearby Harry Hines Boulevard. To reduce the impact on traffic, the agency plans to do much of the work at night using a movable concrete barrier and zipper machines to detour traffic around construction zones.

[edit] Northern section

The North Texas Tollway Authority started work in January 2006 at seven north Dallas locations to improve ramps and add merging lanes. The project will cost US$14 million. To create room for construction crews, northbound motorists have been pushed toward the concrete barriers.

Northbound projects include adding acceleration or auxiliary lanes between Keller Springs and Trinity Mills roads and between Alpha and Spring Valley roads.

Southbound projects include adding outside lane pavement at the President George Bush Turnpike exit; between the Bush Turnpike entrance ramp and Frankford Road; between the Frankford entrance ramp and Sojourn Drive; around the Keller Springs exit at the main lane toll plaza; and between the Keller Springs toll plaza and Spring Valley.

The projects will noticeably lengthen many shorter merging lanes, including one at Trinity Mills where vehicles must merge quickly after driving around a curve.

[edit] Future extensions

Having completed the third extension north, NTTA plans to further extend Dallas Parkway from US 380 to the Grayson County line. It is planned to be a 13.5-mile (21.7 km) extension. Currently, a two-lane county road (which is currently being upgraded) is being built from US 380 to FM 428 in Celina; north of FM 428 a route has not been established, but NTTA has approved hiring of a corridor manager for this project. ^[4]
