NTTA One Step Closer to Starting Work on South Section of DNT Improvements Project

NTTA One Step Closer to Starting Work on South Section of DNT Improvements Project

In late January, the NTTA’s Board of Directors approved contracts for the improvements on the Dallas North Tollway between the Bush Turnpike and I-635. Construction in this area is set to begin this spring.

Improvements will include:

Project--DNT South Project-Map

  • Restriping to add a fourth lane on southbound DNT between the Bush Turnpike and the Belt Line Road exit
  • Restriping to extend the existing fourth lane on northbound DNT between Trinity Mills Road exit and the 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 the project is complete in early 2018, motorists can expect congestion relief during peak travel times.

In order to facilitate a safe work environment for construction crews and the public, the speed limit on the Tollway will be lowered. The 60 mph speed limit will extend south from the Bush Turnpike in the current construction area to Frankford Road. The speed limit between Frankford and Belt Line Roads will be lowered to 55 mph. These enforceable speed limits will begin when construction commences and will remain in place for the duration of construction. The NTTA will make every 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 from Trinity Mills Road to the Sam Rayburn Tollway and southbound from the Sam Rayburn Tollway to the Belt Line Road exit.
