Dallas North Tollway (DNT)

The Dallas North Tollway is a quick, safe and convenient connection for drivers between downtown Dallas and US 380 in Frisco. The 32-mile road crosses through the cities of Dallas, Highland Park, University Park, Addison, Farmers Branch, Plano and Frisco. 

The first section of the tollway opened to traffic in June 1968 between downtown Dallas and Interstate 635 (LBJ Freeway). It was extended north to Briargrove Lane (just south of Frankford road) in 1987 and to the Sam Rayburn Tollway (SRT) in Plano in 1994. A 1.5-mile extension opened in 2004 up to Gaylord Parkway in Frisco, and the northern most extension to US 380 opened to traffic in September 2007. 

NTTA will continue to extend the tollway to new destinations as the region’s northern communities continue to grow. The proposed Phase 4 extension will run nearly 14 miles from US 380 to the Collin/Grayson county line.

Dallas North Tollway (DNT) Widening in Frisco

The Dallas North Tollway (DNT) is being widened between the Sam Rayburn Tollway (SRT) and US 380 to accommodate population growth in the area and improve access to business and entertainment venues. This project will add an additional lane in each direction and help traffic flow as population growth continues in northern Collin and Denton counties.

Along with widening the DNT mainlanes, the project team will reconstruct the intersection and DNT bridge over Fields Pkwy in Frisco.

Opening date: Late 2025.

Concrete barrier placement.
Center median excavation.

Project Sections

Scope

SRT to US 380

Addition of a fourth lane in each direction

Recent Progress

  • SRT to US 380: Construction began August 15. Crews placed concrete barriers to create work zones at the Panther Creek Pkwy intersection and on the mainlanes.
  • In October, the DNT was narrowed to two lanes in each direction north of Panther Creek Pkwy for crews to widen the DNT bridge over Fields Pkwy.

What's Next?

  • SRT to US 380: Work at the Panther Creek Pkwy intersection will continue.
  • The northbound DNT bridge over Fields Pkwy was removed in late October. Reconstruction of the northbound bridge will continue into 2023.

Project Sections

Scope

Phase 4A

US 380 to FM 428, including DNT extension over US 380

Phase 4B Frontage Road

Two-lane frontage road from FM 428 to Grayson County line

Phase 4B Mainlanes

FM 428 to Grayson County line

Proposed Grayson County Tollway

A Grayson County Regional Mobility Authority project that could extend the toll road into Grayson County (not an NTTA project)

Recent Progress

  • Phase 4A: Crews placed concrete for the DNT bridge widening over PGA Pkwy. Retaining wall work at entrance and exit ramps continued for the DNT extension over US 380.
  • Phase 4A: Design of the DNT 4A mainlane extension from US 380 to FM 428 continues.
  • Phase 4B Frontage Road: Work was completed and the frontage road opened to traffic on Monday, October 3. This initial build is a two-lane road. This road is not tolled and will serve as the future southbound frontage road when DNT mainlanes are constructed in this area.

What's Next?

  • Phase 4A: Crews will continue work on mainlane retaining walls and sign structures for the DNT extension over US 380.
  • Phase 4A: Design of the DNT 4A mainlanes continues.
  • Coordination with stakeholders and partners continues.
