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"– is now in effect at 1900 West and 5600 South between 2050 West and Wardleigh Rd. This configuration will be in place for approximately 3-months.
Key Driver Reminders:
- No left turns from 5600 South onto 1900 West (east and westbound)
- Additional left turn restrictions at I-15 off ramps
- Stay alert for new traffic pattern
- Plan ahead to reach your final destination safely
Watch the video below to learn how to navigate the temporary Thru-U.
5600 South (SR-97) – Bridge Beam Installation
Earlier this month, crews successfully installed bridge girders (beams) on the south side of 5600 South bridge over the Union Pacific Railroad (UPRR). This operation was completed over night, each night throughout the weekend, and required long hours, a large support crew, and utilitizing state-of-the-art equipment to ensure a safe and efficient installation.
More details of the bridge installation will be shared in future updates.
Crews completed preparation activities to install the new bridge girders over the UPRR bridge.
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.
