PUBLIC COMMENT PERIOD: MARCH 14 – APRIL 28, 2025
Comment on the Draft EIS, specific to the preferred alternative, the analysis of the potential impacts of the preferred alternative, and the proposed mitigation of the potential impacts. Formal comments must be postmarked or received by April 28, 2025 at 11:59 p.m. MST.
The Utah Department of Transportation (UDOT) has prepared a Draft Environmental Impact Statement (EIS) to improve transportation-related safety and mobility at the I-80 and SR-224 interchange and on SR-224 from Kimball Junction through the Olympic Parkway intersection. After evaluating the information in this Draft EIS, the project file, and public and agency input to date, UDOT has identified Alternative C: Intersection Improvements with Pedestrian Enhancements as the preferred alternative.
Study Overview
UDOT’s mission is to keep Utah moving while enhancing quality of life through transportation improvements in our state. UDOT is conducting an Environmental Impact Statement (EIS) to improve regional and local mobility at the Interstate 80 (I-80) and SR-224 interchange at Kimball Junction and on SR-224 from Kimball Junction through the Olympic Parkway intersection in Summit County, Utah.
The purpose of the EIS is to address transportation-related mobility for all users of the Kimball Junction area. The alternatives being carried forward in the EIS include:
- Taking no action
- Alternative A: split-diamond interchange and intersection improvements
- Alternative C: intersection improvements with pedestrian enhancements
Study Area
The needs assessment evaluation area includes the I-80 and SR-224 interchange at Kimball Junction and SR-224 from Kimball Junction through the two at-grade intersections on SR-224 at Ute Boulevard and Olympic Parkway. The evaluation area also extends from milepost (MP) 143.2 to MP 145.6 on I-80.
Current Phase
Revised: 3/14/25
Draft EIS Published and Identifies Alternative C as Preferred Alternative
UDOT has prepared a Draft Environmental Impact Statement (EIS) to improve transportation-related safety and mobility at the I-80 and SR-224 interchange and on SR-224 from Kimball Junction through the Olympic Parkway intersection. After evaluating the information in this Draft EIS, the project file, and public and agency input to date, UDOT has identified Alternative C: Intersection Improvements with Pedestrian Enhancements as the preferred alternative.
Key features of Alternative C include:
- I-80 Ramps: Additional lane to the eastbound off-ramp to SR-224 and a dedicated right turn lane to southbound SR-224, and an additional lane on the eastbound on-ramp from SR-224.
- SR-224 Intersections: Improvements at Ute Boulevard and Olympic Parkway, including added turn lanes, additional through travel lanes, and bike lanes.
- Roundabout & Local Roads: A second lane was added to the southern approach of Ute Boulevard/Landmark Drive roundabout, and a new lane from SR-224 on Newpark Boulevard to the Olympic Parkway roundabout.
- Pedestrian & Bicycle Improvements: New east-west pedestrian underpass under SR-224 near Ute Boulevard, new buffered bike lanes from Olympic Parkway to Rasmussen Road, and trail connections to the pedestrian undercrossing.
Benefits of Alternative C:
- Greatest reduction in travel delay and faster travel speeds in the study area during AM & PM peak periods
- All intersections in the study area would operate at acceptable levels of service
- Shortest I-80 off-ramp vehicle queue lengths
- More reasonable expenditure of funds for the anticipated operational benefits
