The Pennsylvania Department of Transportation’s Replacement of the Hulton Bridge near Oakmont, PA, involved the replacement of a two lane truss bridge with a new 1,633 LF four lane five span haunched girder bridge erected upstream of  existing bridge on the Allegheny River.  Abutments 1 and 2, as well as Pier 1, include H-Pile foundations.  River Piers 2, 3 and 4 are founded on eight each, five-foot diameter caissons with Piers 2, 3 and 4 requiring the use of cofferdams.  A portion of the main span was erected over the active channel by strand jacking a 1,200 ton, 283 foot long and 60 foot wide segment to final elevation – a first for both Brayman and PennDot.
