If you’ve used Bangerter Highway recently, you’ve likely noticed construction at the 13400 South intersection. Last fall, the Utah Department of Transportation began construction at the intersection to replace stoplights with an interchange. 

When construction is completed in the fall of 2025, Bangerter will run underneath 13400 South, unlike the interchange at 12600 South, where the highway passes over the street. “Bangerter will be moved down so that it passes under a new bridge that will hold 13400 South,” Herriman Communications Manager Jon LaFollette said. 

“We’re grateful and excited that UDOT is working on this project that affects so many of our residents as they travel to and from the city,” Herriman Mayor Lorin Palmer said. 

The two merging lanes connecting eastbound 13400 South to southbound Bangerter have been collapsed to one lane. 

“This traffic shift will allow additional room for crews to work on the Rose Creek Canal,” UDOT’s website says. Rose Creek crosses Bangerter just south of 13400 South. The pedestrian bridge at 13400 South has also been permanently removed.

Over the last weekend in April, utility relocations caused the closure of both northbound and southbound lanes of Bangerter from 12600 South to Redwood Road, and Herriman residents can expect more closures during the upcoming months. Day or night, lanes may shift or close altogether, and reduced speed limits will be in effect. 

“This project occurs outside of Herriman but greatly affects our residents,” Herriman’s website states. 

UDOT advises drivers to expect traffic delays. Beginning this fall, 13400 South will be closed to both east and westbound traffic where it crosses Bangerter until the summer of 2025, about 10 months. Drivers will continue to have access to westbound 13400 South from northbound Bangerter for the duration of construction. 

“These closures are a crucial part of the project to help maintain the safety of both our workers and the traveling public…” UDOT’s Bangerter Project Director Marwan Farah said. “A 10-month closure will help us excavate where 9800 South and 13400 South at Bangerter Highway intersect and start constructing freeway-style interchanges similar to 10400 South and 11400 South.” 

 “Once the 13400 South, 2700 West and 9800 South interchanges are done, traffic won’t be perfect, but it’s going to be a big step in the right direction,” Palmer said. “We’re thankful to the state legislature and UDOT for realizing the major needs for transportation in our corner of the valley and responding through prioritized funding.” 

To reduce expenses associated with storage and transporting debris, crews will store materials and machinery on Mountain View Corridor between 12600 and 13400 South until late 2025. Workers will also likely conduct operations at this site to crush recycled concrete for use on Bangerter. 

“Recycling of concrete also contributes to UDOT’s efforts to reduce construction waste in landfills and importing materials from gravel pits,” UDOT’s website states. “This demonstrates UDOT’s commitment to one of its core values, to be fiscally responsible.” Neighbors may notice noise, vibrations and dust as crews work and construction vehicles enter and exit the site. 

Daytime and nighttime teams are also laboring on the pond and storm drain located on the southwest side of Bangerter where it crosses 13400 South. During construction, noise is possible around the clock. 

“Vehicles are not allowed to park along Innovation Drive on the southwest side of Bangerter Highway as it is a construction site entrance,” UDOT’s website says.

To increase the safety of construction workers and the public, Herriman has asked drivers to use caution in work zones, be aware of crews, reduce speed and follow traffic signs. 

“Please note that even though you might not see workers actively working on the roadway, the traffic control devices are in place for a reason, including the safety of both drivers and crew members,” UDOT’s website cautions. 

“The department has been working to improve this corridor for over a decade… The Bangerter South project will optimize mobility from 4700 South in West Valley to I-15 in Draper. This will be a major milestone for this corridor, not only for the department but also the surrounding cities,” Farah said. λ
