The Utah Department of Transportation (UDOT) has prepared a Supplemental Environmental Assessment (SEA) to evaluate improving the transportation network in and around the half interchange at Interstate 15 (I-15) and 24th Street in Ogden, Utah.
This SEA builds upon the Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) that UDOT completed for the area in 2024.
Following the completion of the 2024 EA and FONSI, the interchange design concept was revised from a single point urban interchange to a folded diamond. This revision changed the location and scope of several proposed improvements to the local street and active transportation networks, as well as right-of-way acquisition needs.
UDOT hosted a public hearing in an open-house format on August 12, 2026, at the Marshall White Community Center in Ogden to share the interchange design concept and solicit feedback on the SEA.
The SEA is available for review at the UDOT website, the UDOT Central Office in Taylorsville, the UDOT Region 1 Office in Ogden, and the Weber County Main Library in Ogden.
