Silver Bridge Eye-Bar
This eye-bar is similar to one that fractured causing the collapse of the Silver Bridge on December 15, 1967. The National Transportation Safety Board found that the cause of the bridge collapse was the cleavage fracture in the lower limb of the eye of eye-bar 330 at joint C13N of the north eye-bar suspension chain in the Ohio side span. The fracture was caused by the development of a critical size flaw over the 40-year life of the structure as the result of the joint action of stress corrosion and corrosion fatigue.
Marker can be reached from Ohio Route 7 0.1 miles north of Georges Creek Road.
