Civil 7 - Willow Creek Bridge Replacement


Student Team: Sophia Nespor, Mitch Beck, Greg Carter, Nathan Sieler
Advisor: Scott Marshall
Sponsoring Organization: HDR
Liaison: Jeremy Miles

Willow Creek Bridge is located southeast of Lake Coeur d’ Alene in Kootenai County, Idaho. The Idaho Transportation Department (ITD) evaluated the existing bridge as structurally deficient and in need of immediate replacement. Our project goal is to complete the design of a new Willow Creek Bridge. Project scope includes completing a hydraulic study of the existing and proposed bridges, a full structural design of the proposed bridge, and drafting all of our design results in AutoCAD Civil 3D. The Hydraulic design involves sizing the bridge openings and channel geometry in order to meet all FEMA floodplain and ITD regulations. The structural design includes the substructure and superstructure, as well as foundations capable of supporting expected traffic loads. The project scope also includes full roadway design to meet ITD standards.
