Dallas North Tollway (DNT)

The Dallas North Tollway is a quick, safe and convenient connection for drivers between downtown Dallas and W. First Street in Prosper. The 33-mile road crosses through the cities of Dallas, Highland Park, University Park, Addison, Farmers Branch, Plano, Frisco and Prosper. 

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 Legacy Drive in Plano in 1994. A 1.5-mile extension opened in 2004 up to Gaylord Parkway in Frisco, and an extension to US 380 opened in September 2007. In 2023, the bridges extending the DNT over US 380 into Prosper opened to travel.

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.
