Continuous-flow intersections In 2007, a continuous flow intersection was constructed at the junction of SR-154 and SR-171 (3500 South), one of a very few such intersections in the United States. The intersection is one of the busiest in the state and handles 100,000 vehicles on a typical weekday. In 2011, five more intersections were upgraded to continuous-flow intersections (3100 South, 4100 South, 5400 South/SR-173, 6200 South, and 7000 South) as part of the Bangerter 2.0 project. Another CFI was completed at the 13400 South intersection in 2013. Interchanges UDOT has begun the process of converting several at-grade intersections into grade-separated interchanges, all of them single-point urban interchanges. The first was completed at 7800 South (SR-48) in 2012, followed by one at Redwood Road (SR-68) in 2015. In 2016, a new interchange was completed at 600 West, the first to not replace a pre-existing intersection. At the same time, the nearby intersection at 200 West was converted to right-in/right-out access only. Through 2017 and 2018, the Bangerter Four project converted four intersections into interchanges: 5400 South (SR-173), 7000 South, 9000 South (SR-209), and 11400 South (SR-175). The 7000 South interchange was opened in 2017, while the other three were completed in late 2018. In spring 2020, construction began on a grade-separated interchange at 6200 South, followed by construction of similar interchanges at 12600 South (SR-71) in January 2021 and 10400 South (SR-151) in May 2021. These three interchanges opened on May 19, 2022. Future Eventually, all at-grade intersections on Bangerter Highway between I-15 and SR-201 are planned to be upgraded to grade-separated interchanges. Environmental impact statements (EIS) have been completed for Bangerter intersections at 4700 South, 9800 South, and 13400 South. Construction is anticipated to start at these three locations in Spring 2023. The interchanges at 4700 South and 13400 South will be constructed as single point urban interchanges while the interchange at 9800 South will be constructed as a tight diamond interchange to minimize impacts to the surrounding community.
