The mighty Mississippi River was renamed the mightier Mississippi on Tuesday, by a gathering of federal, state and local officials heralding the deepening of the river's navigation channel to 50 feet between its mouth and New Orleans.
Sean Duffy, executive director of the Big River Coalition, began lobbying in 2012 to deepen the channel of the country's largest superhighway for import and export goods from 45 feet to 50 feet.
