Over the Union Pacific Railroad bridge (UPRR) along 5600 South between 2700 South and 2050 West, crews poured sidewalks on the south side earlier this week and will now move forward with striping and fence installation along the edge of the bridge deck. Additional curb, gutter, and barrier work will take place along 2700 South and extending toward the UPRR bridge. Drivers can expect minimal to intermediate delays as traffic shifts take place during this work.

1900 West & 5600 South – Back to Standard Intersection

In September, crews removed the temporary Thru-U traffic pattern at 1900 West and 5600 South (SR-97). The intersection is now in a standard configuration.

 

Driver Caution: Stay alert and watch for new overhead and lane designation signage. Drive carefully through the intersection as nearby improvements are still under construction.

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!

Current Street Closures:

  • 2700 West (South side) – Closed Sept 8. – Oct.14*
  • 2000 West (North Side) – Closed in late September. – for apporximately 4-5 weeks*

5600 South (SR-97) – Bridge Beam Installation

Late summer, crews successfully installed bridge girders (beams) on the south side of 5600 South bridge over the Union Pacific Railroad (UPRR). This operation was completed over night, each night throughout the weekend, and required long hours, a large support crew, and utilitizing state-of-the-art equipment to ensure a safe and efficient installation.

More details of the bridge installation will be shared in future updates.

Crews completed preparation activities to install the new bridge girders over the UPRR bridge.


I-15 NB Off-Ramp and Riverdale Rd. Access – Exit 338

Earlier this summer, the I-15 northbound off-ramp at Exit 338 (exit 338B) shifted onto the new overpass, which will provide direct access to Riverdale Rd.

 

What to Expect:

  • A new traffic pattern over the completed overpass
  • Updated overhead signage
  • New lane markings
  • Adjusted traffic flow into Riverdale
  • Drivers, be alert for changes in overhead signage, lane markings and traffic flow.

 

Improved Flow and Faster Access

This new traffic pattern is designed to improve traffic flow through the area. By shifting the off-ramp onto the new overpass, drivers will no longer need to stop at the previous ramp intersection, reducing congestion and travel delays. The direct connection to Riverdale Rd. allows for smoother, more efficient movement of vehicles–resulting in a safer and more streamlined driving experience.
