Repairing Pittsburgh's fire-damaged Liberty Bridge is taking longer than anticipated because of the need for a unique fix, say state officials.
Since a Sept. 2 fire damaged a truss cord near the center of the span and diverted all traffic, general contractor Joseph B. Fay Co. and the Pennsylvania Dept. of Transportation have been working around the clock to fix it. Experts working for PennDOT and Joseph B. Fay Co. have been unable to find a similar case of a bridge damaged by fire in the same way, slowing the progress.
