Project Overview

The Utah Department of Transportation has completed the environmental assessment portion of this project and the design phase is underway. This phase includes developing designs for roads, bridges, and pathways. Once design is finalized, this construction project will convert the existing interchange on I-15 at Exit 57 (Cross Hollow Road/Main Street) to a Single-Point Urban Interchange, bringing all left turns on the interstate and intersecting local streets to a single traffic signal.

Additionally, a 12-foot-wide shared-use trail for active transportation via an existing tunnel under I-15 will be installed along with an additional shared-use path running parallel to Cross Hollow Road/Main Street. The existing walkway through the interchange will be removed. Cross Hollow Road and Providence Center Drive/Royal Hunte Drive and Main Street and Old Highway 91 intersections will be widened to include dual left-turn lanes in all directions.

Proposed Benefits:

• Enhancing the safety and operations of intersections.
• Mitigating off-ramp queues extending onto mainline I-15.
• Increased pedestrian and cyclist safety, comfort, and usage at the intersection.
• Ensuring the intersections meet the level of service operating requirements.
• Overall user comfort and connectivity.

What to Expect During Design:

• Right Of Way considerations.
• Stakeholder coordination.
• Noise evaluation.
• Survey and Geotechnical site evaluation and analysis.
• City Council updates.
• Participation in community events.
