UDOT Advances Legacy Parkway Project to Phase 1 for Improved I-15 Construction Flow

The Regional Growth Technical Advisory Committee (TAC) convened on July 30, 2025, to discuss critical updates to the Regional Transportation Plan (RTP) for the Ogden-Layton area. The meeting focused on the amendment process for transportation projects scheduled between now and 2050, emphasizing the need for ongoing adjustments based on funding availability, local priorities, and environmental considerations.

The meeting began with an overview of the RTP, which is structured into phases spanning approximately a decade each. The committee highlighted the importance of the RTP as a foundational document for prioritizing federal, state, and local funding for transportation projects. It was noted that the amendment process is rigorous, involving public input and air quality conformity assessments, ensuring that projects are not pushed through without thorough review.

The committee specifically addressed Amendment Number 4, which includes three key projects. The first project involves updates to the Legacy Parkway, which aims to add a lane in each direction between I-215 and the I-15 interchange in Farmington. This project is being moved to Phase 1, which is expected to enhance traffic flow during the concurrent construction on I-15, potentially saving 9 to 12 months of construction time and providing a $200 million benefit to the I-15 project.

The second project focuses on I-15 in Box Elder County, which will also update the needs and fiscal constraints associated with the project. The third project involves relocating another project within the same area, further optimizing the planning and execution of transportation improvements.

The committee concluded the meeting by outlining the next steps, which include a 30-day public comment period followed by a review of the comments and final approval by the regional council. This structured approach ensures that the transportation planning process remains responsive to community needs and funding realities.
