The Dallas North Tollway (DNT, or simply the Tollway) is a 30.2-mile (49 km) controlled-access toll road operated by the North Texas Tollway Authority (NTTA), which runs from Interstate 35E near Downtown Dallas, Texas (USA), to U.S. Highway 380, in Frisco, Texas. On December 20, 2023, the NTTA announced the Tollway's next extension which runs 6 miles (9.7 km) through Prosper and Celina and ends at FM 428.^[2]

The Dallas North Tollway was the first toll road in the United States to implement electronic toll collection technology, with the introduction of the TollTag in 1989. TollTag users were originally charged $0.05 extra per transaction, but by 1999, the agency moved to the active encouragement of TollTag use by giving tag users a discount off the cash toll rate. In August 2007, the NTTA announced plans to phase out staffed toll booths entirely by May 2010.^[3][4] The Tollway was converted to all-electronic toll collection on December 11, 2010.^[5]

North of Interstate 635, the Dallas North Tollway is accompanied by frontage roads, which are designated as Dallas Parkway for address purposes. Historically, Dallas Parkway has demarcated future Tollway construction, and properties along the Tollway actually carry a Dallas Parkway address. Currently, Dallas Parkway extends to Gunter, about 4 miles (6.4 km) west of the Gunter central business district, and 51 miles (82 km) north of Downtown Dallas.^[6]
