DNT Main Lanes and Frontage Road Widening (SH 121 to US 380)
Dallas North Tollway Main Lane Widening
The North Texas Tollway Authority (NTTA) is adding a fourth lane to both the northbound and southbound direction of the Dallas North Tollway (DNT) between the Sam Rayburn Tollway (SRT) 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 the population growth and mobility demands in North Texas. Visit NTTA.org for more information about the DNT Fourth Lane Project.
Dallas Parkway Frontage Road Widening
During the DNT widening project, the City of Frisco will begin a separate project to construct additional lanes on 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.
Traffic Management and Updates
City traffic and transportation engineers monitor road-ways and traffic patterns from the Emergency Operations Center (EOC) The engineers are able to adjust signals and keep traffic flowing with innovative technology in the command center.

Drivers are asked to stay alert to changing conditions, reduced speed limits and watch for construction vehicles entering and exiting the work zone. Frisco leverages two-way data sharing with Waze through their Waze for Cities Program which displays traffic alerts reported by Wazers. Use the Waze App to navigate around road closures. Learn more about the Waze App and install it on your smartphone (available in the App Store and Google Play).
Notes Concerning Construction Activity
Construction work is dependent on the weather. The information we provide regarding all construction timelines and activities is weather permitting which means the work is anticipated to happen in that timeframe or the next available date when the weather allows. Rain will cancel most construction activity. In addition, certain activities require specific temperatures or dry weather for a previous number of days before execution. Construction schedules change, sometimes with little notice, for any number of reasons. We appreciate your patience.
