Dearborn River High Bridge

The Dearborn River High Bridge is a steel road bridge crossing the Dearborn River near Augusta, consisting of four spans with wooden decking. The structure extends approximately 251 feet (76 m) and rises about 100 feet (30 m) above the water level.

The bridge was constructed in 1897 by the King Bridge Company of Cleveland to provide essential passage for homesteaders seeking connection to railroad networks. This structure became vital infrastructure supporting early settlement and commerce in the region.

This crossing held significance as a passage point in the regional landscape long before modern infrastructure was built. The area retains a sense of being a gathering place along an important route.

The bridge is located approximately 15 miles (24 km) southwest of Augusta on Lake Bean Road and remains open to local traffic. Visitors should note that the approach follows rural roads, and daytime visits are advisable for better viewing and navigation.

This is the last remaining pin-connected Pratt half-deck truss in the United States, with decking attached at the center rather than the usual position. This constructional detail makes it a rare engineering survivor worth noting for those familiar with bridge design.
