The Dallas North Tollway is undergoing construction stretching for 12 miles from the Sam Rayburn Tollway to Interstate 635 (LBJ Freeway) in Collin and Dallas counties.
The construction is expected to be finished in early 2018.
There are four project sections:
From the President George Bush Turnpike to the Sam Rayburn Tollway: a fourth lane is being added in both directions. The DNT/PGBT interchange is being reconfigured with extra lanes being added. Re-striping and extra lanes are being added near the Belt Line Road and Trinity Mills exits. Along the entire project, new pavement is being put down and crews are moving the light poles from the center median to the outside.
Big upcoming closures:
• Demolition of the Tennyson Parkway Bridge will continue.
• Reconstruction and relocation of the DNT/PGBT northbound ramps.
• DNT southbound Trinity Mills entrance ramp will close in March for six months.
