Endangered: Holliwell Covered Bridge

Preservation Iowa's 2026 Most Endangered List: Holliwell Covered Bridge, Madison County

Spanning the Middle River near Winterset, the Holliwell Covered Bridge is one of five remaining original covered bridges in Madison County. The bridge was completed in 1880 by Harvey P. Jones and George K. Foster at a time when timber truss bridges were practical and economical in areas where wood was plentiful. Having a roof and sides slowed the deterioration of the timber framework, extending its lifetime. At 110 feet, the Holliwell Bridge is the longest of the extant Madison County covered bridges. It remains in its original location and carried vehicular traffic until the mid-1980s. The bridge was placed on the National Register of Historic Places in 1976.

Today, the Holliwell Bridge is a reminder of an era of wooden bridges before the widespread use of iron. Madison County’s famous covered bridges, including the Holliwell, draw thousands of tourists each year. The Holliwell Bridge was also a filming location for the 1995 film The Bridges of Madison County.

Lacking substantial maintenance since the mid-1990s, the bridge’s structural integrity has become compromised. The deteriorating truss members are causing the bridge to lean, and decay and erosion are taking its toll on the bridge’s roof, floor beam supports and abutments. Without repair, the bridge will likely have to be closed to the public within the next 10 years.

The covered bridges are owned by Madison County and maintained by the Secondary Roads Department which is responsible for the upkeep of over 220 bridges leaving limited resources for the maintenance of a non-vehicular bridge. Over the past few years, the County has sought to find alternative funding for repairs to the bridge but has not yet been successful.
