Bison roaming a bridge over the Mississippi River? ‘Crazy’ idea for national park near Quad Cities gains momentum

A plan to convert the Interstate 80 bridge over the Mississippi River into a 100-acre national park where bison would roam between Illinois and Iowa near the Quad Cities is gaining momentum. Dubbed the Bison Bridge, the project is driven by the fact that the current I-80 bridge has been deemed obsolete and in likely need of replacement.
