Description: These two identical Pratt through trusses extend across Big Creek in the village of Bertram in southern Linn County. A bridge plate indicates that it was built by J.E. Jayne and Son of Iowa City, Iowa, in 1891. Minutes of a meeting of the Linn County Board of Supervisors in January 1892 reported that the 224-foot Bertram Bridge, with iron tube piers and two 20-foot approaches, had cost an aggregate sum of $2,927. The Pratt through truss style was utilized on many bridges build in Linn County in the late nineteenth and early twentieth centuries. Since its construction, the Ely Street Bridge has carried sparse traffic and currently maintains a high degree of both structural and historically integrity.
