The National Transportation Safety Board says in a report Thursday it wants states and cities to make sure their bridges don’t have corrosion like what they found on the Pittsburgh bridge that collapsed last January.
Investigators looking into the collapse of a Pittsburgh bridge want transportation officials nationwide to examine more than 10,000 other bridges with similar construction to ensure they don’t have the same kind of corrosion that was found on the bridge that collapsed.
Rust that caused the deterioration of the Pittsburgh bridge’s steel legs and allowed holes to form in the structure was noted on every inspection done since 2005, including one completed just four months before the Fern Hollow Bridge collapsed on Jan. 28, 2022. Work was done in 2009 to clear the debris clogging the bridge’s drainage system, but that wasn’t repeated in the years since even after inspectors said in every report between 2011 and 2021 that the drains had become clogged again.
“Safe, reliable infrastructure is a top priority of the Shapiro administration, and we are committed to ensuring Pennsylvanians and all motorists can travel across the Commonwealth safely,” Campbell said. “To that end, PennDOT remains proactive in its review, analysis and maintenance of its bridges.”
It’s not clear how widespread these issues are nationwide. But the NTSB wanted to urgently call them to bridge owners’ attention even though it hasn’t completed its investigation of the Pittsburgh bridge collapse.
