The Utah Department of Transportation (UDOT) has released the final State Environmental Study (SES) that evaluates the realignment and extension of U-111 from 11800 South to Herriman Boulevard in South Jordan and Herriman, Salt Lake County, Utah.

This study was done to address the current and future growth in southwestern Salt Lake County and the surrounding areas, improve regional system linkage and mobility, reduce future (2050) traffic delays at the U-111 and 11800 South intersection and improve pedestrian and bicyclist mobility throughout the study area.

  • Constructing a new signalized intersection at U-111 and 11800 South 

  • Constructing an intersection on U-111 to facilitate a connection with the future Herriman Boulevard extension 

  • Constructing pedestrian and bicyclist facilities along the U-111 alignment and a grade-separated crossing at Midas Creek

 

 

What is U-111?

UDOT is referring to this study as the "U-111 Environmental Study" as a possible extension is evaluated. Locals may know U-111 as Bacchus Highway, S.R. 111, 7300 West or 8400 West. If a build alternative is selected after the study, a naming convention and road designation would follow.
