The Big River Coalition inform that the following transits restrictions have been established to allow traffic to pass during rock removal work operations at locations C-100 and C-101 (Thebes, IL). The restrictions may be changed based upon conditions, including weather and experience with vessels passing while the rock removal operations are being conducted. The original request for these locations called for full channel closures and these new transit restrictions resulted from passing a test tow through this reach of the Upper Mississippi River (UMR).
