New Traffic Pattern Reminder – 5600 South & I-15 Interchange

The Single-Point Urban Interchange (SPUI) at 5600 South and I-15 is now in its final configuration. Drivers are reminded to stay alert to new traffic patterns, lane alignments and updated signage throughout the area.

Traffic movements may feel different than before, take your time, follow signs and signals, and use caution as you travel through the interchange. Driver attention helps keep everyone safe.

How to navigate the new I-15 and 5600 South Interchange

Watch the video below to learn how traffic will move through the new I-15 and 5600 South interchange.

Driver & Pedestrian Notice:

Drivers and pedestrians may notice intermittent construction activities as crews coordinate work around weather conditions and specialized operations. Traffic control devices, including barrels, will remain staged throughout the project area to maintain safe traffic patterns, protect work zones, and allow crews to mobilize quickly when conditions allow–even during periods when active construction is not taking place.

Construction activities will continue to shift throughout the project area as crews complete as much work as possible during winter conditions. Drivers and pedestrians are encouraged to use caution, plan for extra travel time, and follow posted signage and traffic control measures. 

Ongoing Activities

I-15 Lane Closures & Shifts

Crews will complete nighttime intermittent lane shifts and closures on I-15 in both northbound and southbound directions through early May for profile and concrete grinding activities. During this work, traffic will shift to the three middle lanes. Pavement grinding smooths the concrete surface to improve the ride quality for drivers. 

Plan ahead and expect delays during peak travel times.
