Huitt-Zollars prepared final plans, specifications, and estimates for a new 0.8-mile four-lane divided roadway and tolled overpass above Harlem Road on Grand Parkway. This segment is part of the SH 99 outer loop of Houston. Huitt-Zollars performed utility investigations, roadway design, drainage/detention analysis and design, traffic control, and SWPPP. Included in the design is a significant elevated section on a two degree curve with a bridge skew of approximately 45 degrees. In addition, a steel span bridge over Harlem Road was designed to accommodate for future widening and a turn-around. Due to constraints of right-of-way and existing frontage roads, retaining walls were required, which would accommodate detention.
