Upcoming and Future Activities
I-15 – Upcoming Traffic Shift
As early as Monday, Jan. 5, beginning at 7 a.m., crews will complete a traffic shift on I-15, that includes restriping and moving traffic to the north to accommodate electrical infrastructure work. In the Riverdale area, signal work and roadway improvements will require intermittent lane shifts through the month of January. Drivers should allow extra travel time and expect periodic delays while traveling through the area.
5600 South and Riverdale Rd. – Intersection & Signal Construction
Beginning in early January, electrical crews will work on traffic signals throughout the corridor, starting with the Riverdale Rd. signal. Signal construction and pedestrian improvements, including work near the Union Pacific Railroad bridge (UPRR) will continue over the next three-four months. Drivers should expect occasional, short-term delays at intersections as work progresses, though the majority of this work will not impact traffic.
Major Milestone Ahead – SPUI Interchange
Construction is progressing toward a major milestone, with the SPUI (Single-Point Urban Interchange) at 5600 South (SR-97) and I-15 to be operational in early April. Once open, this new interchange will significantly improve traffic flow and access at 5600 South, providing long-term benefits for drivers and the surrounding community. Additional details about the SPUI opening will be shared in future updates.

Ongoing Activities
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.
