Repairs to Fire-Damaged Pittsburgh Bridge Pose Unexpected Challenges

Cessna said more than a dozen experts from across the country—including pros from Lehigh and Carnegie Mellon universities—are collaborating to design the bridge’s repair. On Sept. 15, experts recommended installing a second bracing system at the top of the pier, which bears the arched truss. The secondary bracing system offers redundancy to the one already planned, but that plan set the repair back a bit more since those parts also must be fabricated.
