Dallas North Tollway Expansion to Increase Value and Mobility in Region

May 12, 2022

HVJ Associates® is excited to announce their role in the expansion and modification of the Dallas North Tollway (DNT). HVJ will soon perform 117 soil borings on DNT Phase 4 A to provide the Rodriguez Transportation Group (RTG)  with geotechnical engineering and design recommendations for pavement design, bridge design, large sign structures, gantries, and retaining walls along a portion of the DNT.

The DNT has offered quick, safe, and convenient connections for motorists between downtown Dallas and communities in the North Dallas region for decades. To support the continued growth of communities like Collin and Denton counties, the North Texas Tollway Authority (NTTA) has approved new expansions to the DNT from US 380 to Grayson County Line.

HVJ and RTG will contribute to this ambitious and impactful project by providing the design of approximately 3 miles of 6-lane roadways in both directions, ramp toll gantries, and main line bridges from north of US 380 to north of Frontier Parkway.

HVJ’s decades of knowledge of the local geology combined with our extensive experience with NTTA and local municipalities is paramount for the design and deep guidance for building a safe and reliable toll road system that will increase value and mobility in this region.
