5600 South & 1900 West Intersection Nighttime Closure – May 2 

Due to inclement weather, crews have rescheduled overnight paving, milling, and grinding work at the 5600 South and 1900 West intersection for Saturday, May 2 from 7 p.m. to 7 a.m. Drivers should avoid the area and expect delays and detours while traveling through the corridor.

Detour information will be shared in future updates.

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.

Drivers can also expect intermittent daytime single-lane closures at on-and-off ramps over the next 3-4 weeks as crews place the final layer of asphalt. Plan ahead and expect heavy delays during peak travel times.

Nightly Closures at I-15 SB On/Off Ramps in Roy & Riverdale

Crews will continue work along I-15 and 5600 South (SR-97) corridor with the following upcoming closures and traffic impacts. 

April 20 – 25: 5600 South Lane Shifts (2425 West to 1900 West)

Lane shifts will be in place along 5600 South. No on-street parking will be allowed on the north side of 5600 South between 2425 West and 1900 West as crews complete asphalt paving activities. 

April 27 – May 1: Missile Way

Paving activities will take place at night April 27 – May 1, from 7 p.m. to 7 a.m. along 5600 South from the I-15 ramps to Missile Way. Lanes will be reduced into single lane configuration while works takes place.

Plan ahead, expect delays, and use alternate routes during closures.

Ongoing Work 

Along 5600 South & Freeway Park Corridor

Crews will continue installing fencing throughout the corridor this month, including around drainage ponds, along Freeway Park Dr., and the east side of I-15. Work on Mechanically Stabilized Earth (MSE) walls will also continue. These are reinforced walls that hold the ground in place to keep roads and ramps stable and safe.

Crews are completing concrete flatwork near the Dilly Dally's business near 1900 West to 5600 South and 2700 West. This work includes removal and replacement of curb, gutter and sidewalk. Drivers should expect minimal delays and business access will be maintained.

Additional work will take place at the drainage pond near Lindquist Mortuary in mid-April, including underground tie-ins (UTB), which connect storm water and drainage systems to the new infrastructure, along with nearby property and parcel cleanup. Crews will also continue lighting and meter relocations throughout April, with ongoing signage installation across the corridor.

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

Lane Closure – 1900 West & 5600 South Intersection 

Earlier this month, crews closed a lane and implemented intermittent business access restrictions along 1900 West. A westbound right-turn lane closure at the 5600 South intersection will remain in place through early April while crews complete curb and sidewalk work.

The right-turn movement is shifted into the thru lane to maintain traffic flow. Business access continue to be maintained throughout this work. Drivers can expect a temporary pattern and delays during peak travel times. 

I-15 Lane Closures & Shifts

Crews will complete nighttime intermittent lane shifts and closures on I-15 in both northbound and southbound directions through late-April 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.
