Hannibal High School graduate Grace McIntosh looks over the interpretive panel she and other students helped design to accompany construction of the new Champ Clark Bridge at Louisiana. A dedication was held Wednesday, Jan. 15 at Henderson Riverview Park overlooking the new bridge, which opened to traffic last August. Hannibal High was the winner of five teams from four schools that submitted designs for the interpretive marker in 2017. Wording on the top was provided by the team from Pittsfield High School. Also included in the design are pieces from the old Champ Clark Bridge, which stood for more than 90 years. McIntosh is holding a three-dimensional model of the panel. The ceremony was organized by the Missouri Department of Transportation. Speakers included MoDOT Bridge Project Director Keith Killen, New London resident John W. Briscoe of the Missouri Highways and Transportation Commission, MoDOT Senior Historic Preservationist Karen Daniels and a representative from general contractor Massman Construction. Students, local government officials and residents attended. The ceremony was the final official event related to the new Mississippi River crossing.
