SR-172; 5600 West; SR-201 to I-80; Railroad Crossing Bridge

Utah Department of Transportation, Region 2

One of the most advanced model-based design and construction (MBDC) 3D deliveries completed in the country, this project was on UDOT’s top 10 list for 2020-2021. Consor provided construction services to widen and reconstruct five lanes of Portland cement concrete pavement (PCCP) on 5600 West from SR 201 to I-80. The work elements also included a new three-span bridge with geofoam embankment over UPRR right-of-way, reconfiguration of the interchange at I-80 as a diverging diamond, and new signalized intersections at 1730 South, California Avenue, 700 South, and 300 South.

The project team installed 10,588 feet of new storm drain ranging from 12 to 60 inches, five detention ponds, and an outfall structure at the Lee Drain. Coordinating with the Salt Lake City International Airport and five fiber optic companies that had betterments along the corridor, the team installed a new fiber optic hub and new UDOT microduct. Due to the Union Pacific Railroad (UPRR) switch yard and other major industrial and commercial stakeholders, project phasing, traffic control/maintenance of traffic plan, coordination, and daily public engagement updates were critical to project success. The project also required continual coordination with the adjacent 700 South Reconstruction and Mountain View Corridor projects.
