30% of the Design Phase is Complete

This summer, the South Cedar Interchange Improved project reached the 30% milestone for the design phase. Throughout this phase, the project team has worked to solidify several critical and foundational project elements, including: 

• Horizontal and vertical alignments of the interchange

• Interchange roadway configurations

• Locations and positions of major project structures

• Initial Right-of-Way requirements

The project will soon enter the start of its 60% design phase. In this phase, designers will work to determine:

• Sidewalk and park strip alignments

• Traffic signal placements

• Right-of-Way design 

• Utility line relocation

What is "Design-Bid-Build?"

This project follows a "design-bid-build" process, a traditional UDOT project delivery method. This means that the design and construction phases of a project are separated into two distinct contracts. 

The project is in the design contract phase, which will continue through late 2026. This phase determines plans and schedules for project elements such as:

• Geotechnical surveying

• Roadway alignments

• Enviornmental compliance measures

• Right-of-Way negotiations and discussions

• Final interchange design 

After design plans and specifications are finalized, UDOT aims to advertise the project for a construction bid in the fall of 2026. The construction phase is then 

anticipated to start in the spring of 2027 and continue through late 2028
