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.

The Texas Turnpike Authority began issuing bonds in 1955 for its second project, the first 30 mile section of the Dallas North Tollway.

The initial segment of the tollway ran from Interstate 35E to Royal Lane along an old St. Louis Southwestern Railway corridor.

[8] Current tolls vary from $0.40 to $2.15 for a car with it being more expensive closer to downtown; the lone exception is the Eldorado Pkwy.

Due to passing through a previously developed heavily populated area at the time of construction, high noise cancelling walls line the Tollway with numerous signs warning drivers about limited sight distance.

Between Loop 12 and Northaven Road, the Tollway runs about a 1/4 mile west of SH 289 (Preston Road).The Tollway connects with I-635 (LBJ Freeway) near the Galleria Dallas and runs along the eastern edge of Farmers Branch and enters into Addison.

At the Dallas-Collin county line, the Tollway connects with the President George Bush Turnpike and enters the city of Plano.

It connects with SH 121/Sam Rayburn Tollway and enters into Frisco, passing by the Dr Pepper Ballpark and Toyota Stadium.

At the Tollway's southern end, near downtown, the agency has rebuilt the road around the main toll plaza and added ramps at Oak Lawn Avenue.

The tollway authority has completely rebuilt the aging toll plaza, adding a third TollTag express lane in each direction.

This work coincides with major projects by the city of Dallas to rebuild part of Oak Lawn under the tollway, and by Dallas Area Rapid Transit (DART) to build a rail line along nearby Harry Hines Boulevard.

Southbound projects include adding outside lane pavement at the President George Bush Turnpike exit; between the Bush Turnpike entrance ramp and Frankford Road; between the Frankford entrance ramp and Sojourn Drive; around the Keller Springs exit at the main lane toll plaza; and between the Keller Springs toll plaza and Spring Valley.

This six lane extension runs 6 miles (9.7 km) through Prosper and Celina, ends at FM 428, and is expected to cost $460 Million.

This table lists the combined destinations as they would be viewed when traveling in the northbound direction, though southbound exits will occasionally be grouped in a different way.
