What is the bridge height or clearance over the river? Will the bridge be a hazard to boating?

The bridge type study is not yet complete and several profiles for the bridge are still being considered. The relationship between the height of the bridge above the water and the cost of the project is being evaluated to select the most cost effective structure.

Just north of the proposed location the river becomes too shallow for large motorized watercraft such as the St. Charles Belle paddle wheel river boats; however, the river is suitable for canoes and smaller boats at this location. As stated above, the piers will be spaced about 150 feet apart. The clearance will be a minimum of 12 feet over normal water level. This design follows the standards for bridge design as directed by the Illinois Department of Transportation and would allow current boating uses to continue.
