Construction Update | June 18, 2026 

Overnight I-15 Interchange & Ramp Closures – This Weekend

Crews will close the roadway beneath I-15 and 5600 South interchange, including all on-and off-ramps, on Saturday, June 20 and Sunday, June 21 from 7 p.m. to 5 a.m. each night to complete final roadway striping and finishing work. 

As part of the project's final phase, crews will install the permanent roadway markings that help organize traffic movements through the interchange. Crews will also perform minor profile grinding on the ramps to provide a smoother driving surface and prepare for the final pavement striping. 

Detour Information

Refer to the detour map below for recommended routes during the closure. Drivers should plan ahead, follow posted detour signs, and allow extra travel time while traveling through the area.  

Overnight I-15 Lane Closures Continue 

Overnight lane closures on I-15 in both the northbound and southbound directions will continue through the month of June as crews complete final roadway improvements. 

Beginning Tuesday, June 23, drivers can expect overnight lane restrictions for concrete panel replacement, final roadway striping, and other finishing work. All work will take place at night to help minimize impacts to daytime traffic. Drivers are encouraged to slow down, use caution through the work zone, and allow extra travel time.

Overnight Ramp & Lane Closures – Tuesday, June 23

Crews will continue roadway improvements along I-15 with overnight ramp closures and southbound lane restrictions beginning Tuesday, June 23 from 7 p.m. to 5 a.m. Work will include installing a new overhead freeway sign and lighting improvements. Crews previously installed the sign foundations and allowed the concrete to cure before safety placing the new sign structure. 

Drivers should expect overnight lane restrictions, ramp closures, construction crews and heavy equipment in the area. Please slow down, stay alert, and plan ahead for additional travel time through the work zone. 

Refer to the map below for detour routes.

Traffic Pattern Change – Raised Median Installation

Recently, crews installed a new concrete raised median on 5600 South between 2050 West and 1900 West. This work will introduce new left-turn restrictions in the area to improve safety, reduce conflict points, and help improve traffic flow through the corridor. 

During construction, one westbound lane on 5600 South will be temporarily restricted during daytime work hours. Drivers are reminded to slow down, watch for changing traffic patterns and use extra caution while traveling through the work zone.

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 mid-June 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.
