The North Texas Tollway Authority (NTTA) is widening the main lanes of the Dallas North Tollway (DNT) between the Sam Rayburn Tollway (SRT)/SH 121 and US 380 in Frisco. In a separate project, the City of Frisco will construct additional lanes on the northbound and southbound Dallas Parkway, which is the frontage road of the DNT.

Keep up to date on Dallas Parkway lane closures and construction with the City of Frisco's Interactive Story Map.

Drivers, use caution when driving through work zones. Please pay close attention to lane closures and the presence of construction crews.

Dallas North Tollway Main Lane Widening

This is a NTTA project. NTTA is adding a fourth lane to both the northbound and southbound direction of the DNT between the SRT/SH 121 and US 380 in Frisco.  The NTTA plans to demolish the existing bridge at Fields Parkway and reconstruct a wider bridge. The project also includes ramp and intersection improvements, and wall stabilization work. The improvements to widen the DNT to eight lanes will help meet population growth and mobility demands. Visit NTTA.org  for more information about the DNT Fourth Lane Project. All questions about the DNT main lane widening should be directed to the NTTA:  progressntta@ntta.org. 

Dallas Parkway Frontage Road Widening

This is a City of Frisco project. As the DNT widening is happening, the City will begin a separate project to construct additional lanes on the Dallas Parkway. These are the northbound and southbound frontage roads of the DNT.  The project will add capacity at the intersections of Lebanon Rd., Stonebrook Pkwy., Cotton Gin Rd., Main St., Eldorado Pkwy. and Panther Creek Pkwy.

Project Coordination and Repeated Closures 

The City of Frisco and NTTA are taking steps to expedite the DNT and frontage road work by increasing work and lane closure hours to 10 or more hours daily at various locations (Panther Creek, Eldorado, Main, south of the BNSF rail line, Gaylord, and north of SH 121). Some working areas are shared by both projects, and some work is unable to begin at a location until the other project has completed work in that location. The increase working hours provide more flexibility for the timelines of both projects.

The extended hours will keep within the City’s noise ordinance. Quiet hours and noise restrictions are specified under Chapter 54, Article IV of the Code of Ordinances. 

The phasing of the DNT widening and the frontage road widening will require some of the work areas to have repeated long-term closures during the construction phases of both projects. Motorists may see a long-term closure end, and then begin again several months later when the other project begins at that location.

The projects are anticipated to be complete in late 2025, weather permitting.
