Ramp Closures:
- All I-15 on and off ramps at 5600 South and the SB I-15 ramp at Riverdale will be closed on Friday, July 18 from 7 p.m. to 5 a.m. This one night closure is needed to accommodate the first phase of the temporary configuration.
Detour Routes:
- I-15 Northbound Traffic:
- Detour via I-84 in Riverdale
- I-15 Southbound Traffic:
- Detour via 650 North (Exit 335)
Beginning This Weekend! Temporary 3-Month Traffic Pattern at I-15 & 5600 South (SR-97)
As part of the I-15 interchange construction, a 3-month, temporary traffic pattern –commonly referred to as a "Thru-U"– will be implemented at 1900 West and 5600 South between 2050 West and Wardleigh Rd. This configuration will be in place this weekend, starting the evening of July 18.
The video below will help drivers understand traffic movements and navigate these temporary routes.

Notice: 5600 South Pedestrian Overpass is now OPEN!
The 5600 South pedestrian overpass near 2700 West closed for approximately two weeks to allow crews to complete fence installation and painting activities.
5600 South (SR-97) Roadway and Paving Operations
Crews are continuing roadway work along the north side of 5600 South between 3500 West and 1900 West. Paving is in progress between 2450 West and 2200 West, with additional paving from 2100 West and 2200 West through July. Driveway access notices will be provided to affected properties. New pavement requires 24-48 hours to cure before driving is allowed. Expect delays and use alternate routes as needed.

Upcoming Work
Temporary Traffic Pattern Coming Soon at I-15 & 5600 South (SR-97)
As part of the I-15 interchange construction, a temporary traffic pattern–commonly referred to as a "Thru-U"– will be implemented at 1900 West and 5600 South between 2100 West and Wardleigh Rd. This configuration is expected to be in place for approximately 3 months, starting the weekend of July 18.
A preview of the Thru-U layout is available below, with a full traffic simulation and navigation guide coming in a future update to help drivers get familiar before the change takes effect.

I-15 NB Off-Ramp and Riverdale Rd. Access – Exit 338
Last month, the I-15 northbound off-ramp at Exit 338 (exit 338B) shifted onto the new overpass, which will provide direct access to Riverdale Rd.
What to Expect:
- A new traffic pattern over the completed overpass
- Updated overhead signage
- New lane markings
- Adjusted traffic flow into Riverdale
- Drivers, be alert for changes in overhead signage, lane markings and traffic flow.
Improved Flow and Faster Access
This new traffic pattern is designed to improve traffic flow through the area. By shifting the off-ramp onto the new overpass, drivers will no longer need to stop at the previous ramp intersection, reducing congestion and travel delays. The direct connection to Riverdale Rd. allows for smoother, more efficient movement of vehicles–resulting in a safer and more streamlined driving experience.
5600 South (SR-97) – Road Closures
Crews will continue excavation and roadway activities throughout the 5600 South (SR-97) corridor between 3500 West and 1900 West along the north side and will temporary close some adjacent streets. Drivers use alternate routes and expect delays.
- 2200 West* (North side) – Closed July 2 – approximately 2-weeks
- 3100 West* (North side) – Closed July 10 – approximately 2-weeks
- 2050 West* – Closed through summer

Pedestrian Safety
Prioritize pedestrian safety while navigating through our work zones. Here are some tips to keep in mind:
- Stay Alert – always be aware of your surroundings. Look out for construction signs, workers, and potential hazards
- Use Designated Pathways – these paths are designated to keep you safe from construction activities
- Avoid Distractions – Refrain from using your phone or wearing headphones while walking through construction areas
- Wear Visible Clothing – Wear bright or reflective clothing, this can help ensure your seen by workers and drivers
Let's work together to keep everyone safe!
I-15 at 5600 South - Bridge Beam Installation Highlights
Over the course of four nights, approximately 20 dedicated crew members installed eight bridge girders (beams) on the new I-15 structure at 5600 South earlier this month.
Each girder weighs about 118,000 pounds and spans an impressive 211 feet. Using large cranes designed for heavy lifting, skilled professionals ensured each beam was safely and accurately positioned to meet engineering standards. Ironworkers played a vital role in fabricating and installing the steel beams, contributing to the bridge's safety and durability for vehicles and pedestrians. Despite colder temperatures, the crews used advanced equipment and techiniques to navigate challenging weather conditions while maintaining safety standards.
Check out some of the highlights below from the project, including the use of cranes, hands on application, and advanced equipment to complete work under challenging conditions.
How can I utilize the pedestrian bridge across 5600 South?
Crews are hard at work on the brand-new pedestrian bridge in Roy City. We're excited for you to start using it! Check out the animation below to see how you can take advantage of this addition to the community.
The bridge over 5600 South is scheduled to be open to pedestrians in spring 2025.
