Oblique View Looking Southwest The bridge has received some attention since the HAER survey was taken. It's had a nice coat of paint and the wood deck has been replaced with a steel mesh deck that rattles when vehicles cross. Photo taken by J.R. Manning in August 2008 |

Lower Chord Eyebar and Vertical Connection This just doesn't look quite right, does it? According to an independent survey, the stringers are a replacement from the original structure, perhaps from another bridge, and adapted to this one. Photo taken by J.R. Manning in August 2008 |

Turtleville Truss Bridge
Written by Jean P. Yearby (1984) from research by George Danko (1977)The Turtleville Iron Bridge carries Lather Road 140 feet, from abutment face to abutment face, across Turtle Creek. It was built in 1887 by the Wisconsin Bridge and Iron Company, and is a Pratt through-truss with pin connections and bottom chord eye-bars. The wooden flooring, covered with an asphalt road bed, is supported by riveted stringers and floor beams. Triangular nameplates are affixed atop each portal. Metallographic examination of three specimens from a post, a counter rod, and a hip vertical, conducted by the Beloit Foundry Company, revealed a typical microstructure of true wrought iron and iron silicate slag. In 1981 the bridge was in fair condition, covered with a layer of oxidation. It has since been scheduled for demolition. The Wisconsin Bridge and Iron Company was founded in 1870 under the name 'Weinhagen Brothers, Engineers.' Its name was changed in 1880.
