Eldean Covered Bridge


The Eldean Covered Bridge is a historic covered bridge spanning the Great Miami River in Miami County north of Troy. The bridge was built in 1860 and is one of the nation's finest surviving examples of a covered Long truss, patented in 1830 by engineer Stephen H. Long. This bridge is one of the finest and least altered examples of this truss type. It is the longest surviving example of its type.

The Eldean Covered Bridge is 224 feet in length for its two spans. It is also the longest example of this type of bridge. It was listed on the National Register of Historic Places in 1975 and was designated a National Historic Landmark in 2016.

Its two-span structure is mounted on cut stone abutments and a central pier. The western abutment and central pier have been capped in concrete, and the pier has a cutwater feature on its upstream side. The total structure length is 231 feet, with each span about 108 feet. The roadway has a width of 17 feet with a total width of 21 feet. The maximum clearance is 13 feet. The bridge is covered by a gabled metal roof, and its exterior is finished in vertical board siding, with small square openings framed on each side to admit light. Approximately 300 vehicles cross the bridge daily.

The bridge is located north of the city of Troy between Concord Township and Staunton Township on a now-bypassed segment of County Road 33. County Road 33 was laid out in 1847 to provide access to a hamlet originally serving the Miami and Erie Canal to the east. The present bridge was built in 1860 and rehabilitated in 1980. It is the second bridge to stand on this site.
