Madison County

Madison County is a rural administrative county in central Iowa featuring agricultural land, small towns, and villages spread throughout its area. The county's territory is crossed by several highways that link it to neighboring regions.

Established in 1846 and named after President James Madison, the county followed a common naming pattern for the era. Local government organization began in 1849 as early settlers arrived.

The six covered wooden bridges scattered throughout the county, including the Cedar Bridge and Roseman Bridge, demonstrate how 19th-century builders solved the problem of crossing rivers. These structures remain popular destinations for visitors exploring rural heritage.

The region is best explored by car, with major roads well distributed throughout and towns connected via routes like Interstate 80 and U.S. Highway 6. The rural character means attractions and towns are spread out rather than clustered.

A limestone highway tunnel exists in Pammel Park, the only one of its kind in Iowa and a rare structure in this region. This tunnel cuts through a hillside along the Middle River and surprises many visitors.
