Friant-Kern Canal Bridge at Piedra Road

Cornerstone Structural Engineering Group was retained by Fresno County to provide construction inspection services for the HBP funded replacement of the substandard bridge railing and polyester concrete overlay on the Piedra Road Bridge over the Friant-Kern Canal. The project included the removal of the existing bridge barrier rail and a portion of existing bridge deck, construction of new bridge deck in the exterior bays and placement of a new steel barrier rail, joint seal replacement, and polyester concrete deck overlay in accordance with the May 2006 State of California Standard Specifications. Since the existing bridge is over a deep canyon construction activities required the use of a mobile scaffolding system atop the bridge deck which extended over the edge of deck and under the bridge.
