QUINCY, Ill. (AP) -- Emergency crews are working on and keeping a close eye on a 52-mile levee along the Mississippi River near Quincy.

Officials with the Illinois Emergency Management Agency say National Guardsmen, prison inmates and others continue to sandbag the Sny levee. They say workers are also using a bulldozer to push the base of the levee to make it higher.

IEMA spokeswoman Patti Thompson says the levee is expected to crest Monday or Tuesday. She says crews will remain at the levee after it crests to make sure it holds.

Thompson says the levee that runs through Adams and Pike counties must be watched after it crests because of the tremendous amount of water pushing against it. She says crews have to make sure the water doesn't breach the levee.
