Information
Our team, W3SM Engineering, is a group of seniorlevel civil engineering students tasked with the design of the Franklin Boulevard Interchange in Canyon County, Idaho. Population growth in the Treasure Valley has begun to stress traffic flow conditions for I-84 and its interchanges, creating need for new interchange design. Our efforts will be directed to increase capacity and make driving conditions safer, while remaining environmentally and commercially friendly. Current ramp traffic flow peaks at 630 vehicles per hour (vph), and is expected to rise to 1,892 vph by the year 2030. Additionally, the overpass span must be lengthened to support six total interstate lanes, increased from four. Using principles of transportation, structural, geotechnical and environmental engineering, we will redesign the interchange on/off ramps, bridge, and traffic control to accommodate our community’s growing needs.
