Clarion and Venango Counties, PA
Dawood supported the NBIS in-depth special inspection of the Emlenton Bridge carrying I-80 over the Allegheny River in Clarion and Venango Counties. The Emlenton Bridge is classified as fracture critical, meaning it contains a member in tension whose failure would cause the bridge or a significant portion of the bridge to fail. The Emlenton Bridge is composed of two multi-beam approach spans and a three-span, 84-foot deep deck truss. Completed soon after the collapse if the I-35W Bridge in Minnesota, this special inspection was intended to inspect gusset plates and fracture critical members of the deck truss. Dawood provided in-depth hands-on inspection of fracture critical members of the deck truss that are accessible from a deck snooper paying close attention to fatigue sensitive details.
