Dallas Area Rapid Transit (DART) and the North Texas Tollway Authority (NTTA) have agreed to an overnight closure of the Dallas North Tollway (DNT) between Belt Line and Keller Springs roads from 10 p.m. Saturday, April 6, to 5 a.m. Sunday, April 7. This closure is needed to set a new pedestrian bridge that is part of a regional hike and bike trail that follows the alignment of the DART Silver Line Regional Rail Project.

Southbound DNT drivers will take the Keller Springs Road exit ramp, remain on the frontage road, and reenter the DNT at Belt Line Road. Northbound DNT drivers will exit at Belt Line Road, continue onto the frontage road, and reenter the DNT at Keller Springs Road.

All main lanes of the DNT will be closed as crews from Archer Western Herzog (AWH), DART’s design-build contractor, set the pedestrian bridge that will connect Addison and Dallas over the tollway near Arapaho Road. The bridge is scheduled to open to pedestrian traffic later this fall.

“Addison and Dallas residents have repeatedly asked us about the trail and pedestrian bridge in this area, so we are excited that they can now see the plans and renderings we have discussed become a reality. Safety on this project is a priority, so while we plan to connect the trail and open the pedestrian bridge later this year, we ask for everyone’s continued patience as we make progress on Silver Line construction,” said Trey Walker, DART vice president for capital design and construction.

DART and NTTA agreed on the overnight closure to ensure the safety of the traveling public and construction workers while limiting the impact of construction on DNT traffic. AWH crews previously set a rail bridge for the future Silver Line in March and drivers can expect additional evening lane closures as DART and NTTA wrap up work in the area on the DNT.

The DART Silver Line is a 26-mile commuter rail that traverses seven North Texas cities (Grapevine, Coppell, Dallas, Carrollton, Addison, Richardson, Plano) between DFW Airport and Shiloh Road in Plano. The regional rail alignment crosses three counties (Collin, Dallas, Tarrant) and will provide service to improve mobility and accessibility across the northern portion of the DART service area. DART Silver Line revenue service is scheduled to begin in late 2025 to mid-2026.

The Regional Transportation Council (RTC) approved funding for engineering design of the trail from DFW Airport to Shiloh Road in Plano. Currently 4.21 miles of the trail corridor exists, with 20.95 miles of the trail programmed with funding for construction as part of the DART Silver Line project. This trail construction is funded by a variety of sources approved by the RTC, Dallas County, the local communities in the corridor, as well as other federal transportation funding programs.
