Ed Hand Highway Bridge over Vermilion River

HEI was selected by the LaSalle County Highway Department to provide preliminary engineering services for the replacement of the bridge carrying CH 23 (Ed Hand Highway) over the Vermilion River near Oglesby, IL. Ed Hand Highway is a vital link from the City of Oglesby to Matthiessen State Park, Starved Rock State Park, and the Village of Utica. The Vermillion River is a popular fishing and canoeing destination.


Due to the historic nature of the bridge the HEI team prepared documentation for historic bridge coordination, which resulted in Section 4(f) approval from the Federal Highway Administration (FHWA). The new bridge was designed to closely follow the existing horizontal alignment and vertical profile to minimize impacts to the surrounding environment. The new three span steel plate girder superstructure is 394 feet long and 34 feet wide including five-foot shoulders to provide bicycle accommodations.
