Riverdale Rd. Exit – Nighttime Closure & Detour  

Crews will temporarily close the Riverdale Rd. exit (Exit 338B) beginning tonight, Thursday, Feb.19 and Friday, Feb. 20 from 7 p.m. to 5 a.m. each night to complete sign and signal installation work. During the overnight closure, drivers will be detoured off Exit 338A to 1900 West. Plan ahead and expect delays.

Crews will also be performing profile grinding along Freeway Park. – which removes a thin layer of pavement to smooth the surface, and prepare for final roadway treatment. One-way flagging operations will be in place to safely direct traffic through the work zone. Plan ahead and expect delays.

3100 West & 5600 South – Signal Prep and Activation

Crews will be installing steel signal arms and activating the traffic signal at 3100 West and 5600 South over the next couple of weeks. The signal will initially operate on a temporary timer until full signal connectivity is established along the corridor from 3500 West to 1900 West along 5600 South. 

Permanent coordination and connectivity with the other traffic signals along the corridor is anticipated to be completed this summer. Drivers should expect possible delays and intermittent backups during peak travel times while the signal operates on temporary timing.

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.

Adjacent 4400 South Project - I-15 Lane Closures 

Through the end of February, there will be lane closures on the inside lanes of northbound I-15 under 4400 South bridge while work occurs in the median. These closures are overnight Sunday-Friday starting at 6 p.m. and 8 p.m. M-F, and ending at 5 a.m. The shoulders will also will be closed on northbound and southbound I-15 during this time. Visit their project website for additional information and what to expect.

Ongoing Activities

Crews are continuing work along 5600 South (SR-97) under I-15 in the SPUI (Single Point Urban Interchange) area, which is an interchange design where traffic entering and exiting the freeway is controlled through one main signalized intersection. Crews are installing curb and gutter, completing removals, finishing earthwork and slopes. In addition, crews are completing hardware installation on bridge girders (beams) and setting junction boxes in preparation for upcoming concrete work. Once prep work is complete, final boxes will be set and UDOT fiber will be installed running both east and west.

With the new traffic pattern in place, drivers can expect occasional lane shifts, changing traffic movements, and construction equipment and crew members near the roadway. Please slow down, stay alert, and follow all posted signs while traveling through the area.

5600 South and Riverdale Rd. – Intersection & Signal Construction 

Crews are completing signal and pedestrian improvements at the intersection of 5600 South and Riverdale Rd. as part of the ongoing construction project. This includes work near the Union Pacific Railroad (UPRR) bridge and is expected to continue through the winter months. 

Additional signal work will take place along Riverdale Rd. During the next couple of weeks, drivers should expect a temporary right-turn closure while crews complete installation and foundation placement. As part of the permanent signal and roadway upgrades, crews will also be removing existing traffic-management equipment poles. Drivers and pedestrians are encouraged to plan ahead and use caution in the work zone.

Final Paving Resumes This Spring on 5600 South & 1900 West  

Crews will complete the remaining paving work in the spring, once warmer temperatures return. Asphalt paving requires  specific temperature conditions to ensure long-lasting, high-quality results. While drivers may notice unfinished areas near 1900 West and 5600 South intersection, this work is intentional and temporary.

Why Paving Waits for Warmer Weather

Asphalt is produced at facilities called hot plants, where aggregates (rock and sand) are heated and mixed with liquid asphalt binder. This material must stay hot from the plant to the roadway so it can be properly placed, compacted, and bonded. Completing this work during the winter months can lead to cracks, poor compaction, and a shorter pavement lifespan. UDOT crews source asphalt from certified local hot plants that meet quality and safety standards, ensuring roads are built to last once conditions are right. Waiting for spring temperatures helps deliver smoother, safer, and more durable roads for Utah drivers.

5600 South – Intermediate Lane Closures

Through the winter months, crews will implement occasional intermediate lane closures along 5600 South in both directions to accommodate finalizing flatwork (curb, gutter, sidewalk) between 2700 West and 3500 West. Crews will maintain one lane in each direction. Drivers should plan for slower traffic and delays during peak commute hours.

Pedestrian Safe Walking Routes

Safe walking routes were updated to include the activated HAWK (High-Intensity Activated crossWalk) light at 2100 West along 5600 South. Drivers: Slow down and be aware of the designated safe walking routes along 5600 South. Stay alert, watch for students and pedestrians in the area.

Pedestrian Safety

Prioritize pedestrian safety while navigating through our work zones. Here are some tips to keep in mind:

• Stay Alert – always be aware of your surroundings. Look out for construction signs, workers, and potential hazards
• Use Designated Pathways – these paths are designated to keep you safe from construction activities
• Avoid Distractions – Refrain from using your phone or wearing headphones while walking through construction areas
• Wear Visible Clothing – Wear bright or reflective clothing, this can help ensure your seen by workers and drivers

Let's work together to keep everyone safe!
