Eagle Interchange Improvements

Faculty Sponsor

Dr. Molly Gribb


This is a senior design project for the Eagle interchange located along I-84 in Meridian, Idaho. Currently, it is one of the most heavily used interchanges in the state with average daily traffic volume of 17,000 vehicles. The traffic flow along this interchange is expected to grow to 25,000 vehicles per day by 2030. To satisfy this increase in volume, an innovative diverging diamond interchange has been selected to meet Idaho Transportation Department design standards for safety and minimal delay. Our project consists of components from each of the following areas of Civil Engineering: geotechnical (foundation design), environmental (permitting and storm water drainage), transportation (road design to meet Level-of-Service D and safe passage of bicyclists and pedestrians), and structural (bridge renovation). Upon completion, the design of Eagle Road will be capable of accommodating 2030 traffic volumes at an appropriate level of service.
