PROJECTS1_DNT I-S map

Construction on the third section of the planned Dallas North Tollway Improvement Projects recently took a step closer to the starting line. On Jan. 20, NTTA’s Board of Directors approved contracts for construction on the section of the Tollway between the President George Bush Turnpike and Interstate 635.  Construction in this area is set to begin this spring and is anticipated to be completed by early 2018.

Improvements in this section include:

  • Restriping to add a fourth lane on the southbound Dallas North Tollway between the Bush Turnpike and Belt Line Road
  • Restriping to extend the existing fourth lane on the northbound Dallas North Tollway between Trinity Mills Road and Bush Turnpike
  • Overlaying a new surface on the existing pavement
  • Relocating the existing light poles from the center median to the outside of the roadway

When complete, the improvements in this area will relieve congestion and improve safety.

During construction, the speed limit on the Tollway between the Bush Turnpike and Frankford will be lowered to 60 mph. The speed limit will be lowered to 55 mph from Frankford Road south to Belt Line Road. These enforceable speed limits will be in place during construction in an effort to keep motorists and construction crews safe.

Overall, the entire Dallas North Tollway Improvement Projects includes adding a fourth lane of traffic along the Tollway northbound between Trinity Mills Road and the Sam Rayburn Tollway and southbound between the Sam Rayburn Tollway and Belt Line Road.  NTTA tollway construction is funded solely by tolls paid by drivers.
