Overnight Riverdale Rd – Exit 338B Closure June 10 and 11

Crews will temporarily close the I-15 Northbound Riverdale Exit 338B on June 10 and June 11 each night from approximately 8 p.m. to 12 a.m. to paint the bridge parapets (the protective concrete barriers along the bridge). 

The Freeway Park bridge will be closed. Access to businesses along Freeway Park Dr. will remain open. Drivers can still use the I-15 northbound off ramp at 5600 South (Exit 338A) and follow the detour route via 5600 South to 1900 West to access Riverdale Rd. Please follow posted detour signs, reduce speeds in the work zone, and plan ahead for minor delays.

Overnight I-15 Interchange & Ramp Closures – June 20 & 21 

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

This work includes installing permanent lane markings, directional arrows, and other pavement markings that guide drivers and improve safety.  Additional details and detour information will be shared in future updates.

Overnight Ramp & Lane Closures – Friday, June 14 

Crews will continue roadway improvements along I-15 with overnight ramp closures and southbound lane restrictions beginning Friday, June 14 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.

Overnight Striping Operations & Lane Closures on I-15 

Crews are completing roadway striping on I-15 northbound and southbound between Roy Exit 338 and the Riverdale Rd. bridge through mid-June. Work will take place nightly, excluding the weekends, from 7 p.m. to 5 a.m. and requires lane closures to allow crews to safety install permanent pavement markings, lane lines and other roadway striping that helps guide traffic and improve safety. 

Drivers should expect lane closures, heavy equipment, and crews in the area. Please slow down, use caution and plan ahead for possible delays and detours.

Traffic Pattern Change – Raised Median Installation

Beginning next week, crews will begin installing 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.
