With the potential of several inches of rain over the next few days, the Mississippi River is forecasted to rise well over flood stage.
The City of Hannibal began protecting its downtown by installing all five flood gates on Thursday afternoon.
Access to the riverfront is now blocked off.
The river is expected to crest at 28 feet on Sunday.
At that height, the Admiral Coontz Armory will flood, Warren Barrett Drive will be shut down, and Route 79 will be closed south of Hannibal.
Marion County Emergency Management Director John Hark says the City of Hannibal will install all five flood gates Thursday at 1 p.m.
The riverfront area, east of the floodwall will be closed to all traffic, effective midnight, April 17, 2013, with the exception of emergency traffic and response personnel.
