The structures carry 8 lanes of I-290 traffic over CN Railroad, I&M Canal, Chicago Sanitary and Ship Canal, Metropolitan Water Reclamation District Property, Des Plaines River, the BNSF Rail Yard, Santa Fe Drive, and 75th Street Interchange. Quigg’s responsibilities included the overall management and coordination for the survey, environmental and existing bridge inspection.

Survey tasks included topographic surveys of the bridge and railroad yard, hydraulic survey of canal and right of way surveys using 3-D Lidar scanning.
