Interchanges from Five Mile Road in Boise to the Karcher Interchange in Nampa are being redesigned to help meet the area’s growing population and reduce congestion on the interstate. This senior design project is for the redesign of the I-84 Interchange at Meridian Road. Meridian Road will be expanded to six lanes and the Interstate will be expanded to eight lanes. A Single-Point Urban Interchange (SPUI) was determined to be the most feasible option available that will be able to handle the current and future levels of traffic through the year 2050. The project will include turning lanes, bike lanes across the overpass, and breakdown lanes on the highway designed to meet existing and future traffic needs. Our project also included analysis of geotechnical engineering reports, an environmental assessment, evaluation of existing and future traffic volumes, management of storm water drainage for the site and a preliminary cost analysis.
