Construction Update | Oct. 2, 2025 

I-15 and 5600 South (SR-97)

Crews are completing cast-in-place barrier work in the I-15 median at the 5600 South structure. With removals finished, roadway section reconstruction is now underway. Barrier work continues on the northbound side, and once complete, crews will shift to the southbound side. Drainage work along I-15 northbound mainline is scheduled to begin in mid-October. In additon, painting of structures and MSE wall coating will continue through next week. Drivers can anticipate minimal to intermediate delays during peak hours around the interchange.

Freeway Park Dr. and Riverdale Rd.

Work is progressing on the north end with concrete paving for sidewalks and flat roadway areas along with barrier activities. Next week, crews will begin median work. Drivers can expect one-way flagging with minimal to intermediate delays during the daytime. The Riverdale Rd. exit (Exit 338B) will remain open to traffic.

5600 South, 1900 West and UPRR Bridge Area

At the 1900 West intersection, crews will begin removals on the northeast corner early next week, with paving planned for Oct. 10. Drainage improvements, including new manholes and catch basins, are also underway and will continue through the month of October.

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.

Overview of the UPRR bridge.

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.
