I-10/I-610 Interchange Reconstruction
RS&H prepared the geometric design, as well as construction plans, specifications, and estimates (PS&E) for one of the most heavily congested freeway interchanges in the United States: the four-level I-10 Katy Freeway interchange with I-610 Loop Road in Houston, Texas. This interchange is projected to accommodate over 270,000 vehicles a day by 2023 and was one of ten sections along I-10 reconstructed by the Texas Department of Transportation to improve travel conditions in northwest Harris County.
The project included eight system-to-system directional ramps, four system-to-service ramps, and two high-occupancy vehicle (HOV) flyover ramps to the area’s Northwest Transit Center. Also included were improvements to the area street network, as well as interstate grade separations with surface streets and the Union Pacific Railroad.
Since our geometric design of the interchange affected two adjacent design sections, it was critical to complete the renovations within six months in order to maintain the overall corridor schedule. RS&H completed final plans only 27 months after notice to proceed.
