A 50-year-old bridge that collapsed in Pittsburgh had been rated as poor on a recent inspection report
......
A September 2019 inspection showed the bridge’s deck and superstructure were rated 4 and in what inspectors said was poor condition.
......
WHAT DOES A POOR DESIGNATION MEAN?
......
“A poor rating doesn’t mean bridges are unsafe, it just means one of those components are rated at that level,” Herrmann said.
......
New bridges are rated 9, and bridges with minimal or no wear are rated 7 or 8. Bridges considered in what the federal program deems fair or satisfactory condition — some signs of deterioration or minor loss or cracking — are rated 5 or 6.
When a bridge reaches a 4 rating, it means there is advanced deterioration or section loss, but the primary structural components are still sound. A 3 rating means those structural components are starting to see deterioration, and a 2 or 1 rating means there are critical issues or an imminent failure of the structure is possible.
......
HOW MANY BRIDGES ARE RATED POOR?
......
The most recent report using 2021 data showed more than 43,500 of the country’s roughly 615,000 bridges were rated poor.
That number is about 4,000 less than those reported to be in poor condition nationally in 2017.
......
it’s a glacial pace for repairs and that dedicated funding is critical to catch up.
In Pennsylvania, ...... 3,200 bridges with a poor rating— a drop from five years ago of nearly 1,000 bridges. But more than 2,100 of those bridges have reached a level of deterioration requiring weight or traffic limits.
