7200 West Study (SR-201 to 700 North)

Executive Summary and Final Report (3.1.2019)

Salt Lake County is exploring a northern extension of 7200 West from SR‑201 to approximately 700 North to help establish an important arterial roadway for a multi‑modal transportation network.  As the only undeveloped area remaining in Salt Lake City, the Northwest Quadrant (NWQ) is a regionally significant area for economic development and job growth.  The relocation of the Utah State Correctional Facility, the location of the new Amazon and UPS distribution centers, and an inland port will accelerate development and job creation in this area.

Salt Lake County has contracted with  H.W. Lochner to complete this study.

Study Area

The Northwest Quadrant has many elements that will play an important role in shaping the alignment of the 7200 West northern extension.  The project team has identified the potential constraints along the corridor: 

  • Wetlands prevalent on both sides of 7200 West
  • Proposed Kennecott expansion of tailing ponds to the east to 7200 West
  • Proposed utility corridors
  • Unique design and constructability approach required for the North Temple Landfill
  • Close proximity to the 5600 West and MVC interchanges
  • Potential railroad relocations:
    • Union Pacific Railroad (UPRR) needs to be realigned to accommodate tailings expansion
    • Salt Lake Garfield & Western Railway (SLGWRR) is planning to expand their corridor
