Huitt-Zollars to prepared the final design for Line Section NW-3. As a portion of DART’s Northwest Corridor, NW-3 is approximately 5.5 miles in length and includes three miles at-grade and 2.5 miles of aerial guideway, two elevated stations and one at-grade station, a railroad yard relocation track which leads into the maintenance facility, and track work for future Irving Line connections. Key challenges included numerous street closures, cross street reconstructions, traffic control, major utility relocations, and coordination with highway projects in the corridors. The line crosses IH-635, which is one of the busiest freeways in the nation. The elevated guideway employs efficient Type IV beam structures with track direct fixation.
