Major $238 Million Upgrade of Roy’s 5600 South Corridor Nears Completion

The $238 million upgrade of the busy 5600 South corridor and its I-15 interchange on the eastern edge of Roy is now largely complete, with only minor details pending after three years of work. The two-mile stretch between I-15 and 3500 West now carries two lanes each way plus a center turn lane, replacing the former single-lane configuration, and the interchange has been reshaped to accommodate increased traffic from expanding neighborhoods and the Northrop Grumman Sentinel missile-defense complex.

Utah Department of Transportation purchased roughly 60 parcels along the southern side of the road, demolishing mainly single-family homes to make room for the widening. City Manager Matt Andrews highlighted the improvement’s role in easing peak-hour congestion and supporting future growth, while UDOT spokesman Mitch Shaw noted similar pressures west of I-15 in Davis and Weber counties. A ceremony will be held Thursday afternoon at Roy Elementary School to celebrate the project’s completion, and other UDOT initiatives, such as a new I-15 intersection at 1800 North and the northward extension of the West Davis Corridor, remain underway.
