DNT Improvements

Dallas North Tollway (DNT) Expansion Project

In August 2022, NTTA began construction adding an additional travel lane in each direction of the Dallas North Tollway (DNT) between the Sam Rayburn Tollway and US 380. The widening project will accommodate population growth in the area and improve access to all the businesses and entertainment venues along the DNT in Frisco. The project is scheduled to be completed, weather permitting, in late 2025.

The DNT widening in Frisco is the latest improvement project along the 32 miles of the DNT from Interstate 35E to US 380. These improvements are designed to add lanes, help traffic flow and minimize traffic impacts during preventative maintenance.
