The size and shape of Campbell 's Island has been somewhat variable in historic times , due to additions and subtractions created by the power of the Mississippi River . Today , the island is approximately 1.25 miles ( 2 km ) long and 0.5 miles ( 0.8 km ) wide . It is the home of a suburban community that dwells on a ring road that circles the island . The low-lying Campbell 's Island is subject to flooding , and many of the island homes are raised , built on stilts , or otherwise constructed so as to minimize damage during periods of high water such as the Great Flood of 1993 . The bridge to East Moline was built in 1938 and completely rebuilt in 1999
