For a time , the Bayview Bridge , one of Quincy 's two bridges , was the only bridge open across the Mississippi River between Alton , Illinois and Burlington , Iowa . The Memorial Bridge was closed from the end of June , due to water over its western approach . On July 16 , 1993 , the Bayview Bridge closed when the river submerged the land on the west side of the Mississippi River at Taylor , Missouri ; Quincy 's bridges reopened 73 days later on September 26 , 1993
