CORRECTED-Collapsed Pittsburgh bridge is one of 44,000 in poor condition in U.S.

Jan 28 (Reuters) - The half-century-old bridge that collapsed https://www.reuters.com/world/us/biden-highlight-manufacturing-jobs-gdp-growth-pittsburgh-2022-01-28 in Pittsburgh on Friday ahead of President Joe Biden's visit highlighted the perilous state of much of the United States' transportation infrastructure, which is due to get a trillion-dollar infusion over the coming years.

Like nearly 44,000 other spans nationwide, the Pittsburgh bridge is rated in poor condition, according to the U.S. Department of Transportation's 2021 national inventory.

Ten people sustained minor injuries when the snow-covered span collapsed into Fern Hollow, a wooded gully, at about 6 a.m. (1100 GMT), authorities said. Several nearby homes were temporarily evacuated after a massive natural gas leak caused by the collapse, which was brought under control.

Built in 1970, the four-lane bridge carries an average of 14,500 vehicles per day along Forbes Avenue, one of the city's main arteries, according to the U.S. Transportation Department.

Pittsburgh City Council member Corey O'Connor said the toll from the collapse could have been worse. "If it was rush hour, we would be looking at a couple hundred cars down in that valley," he told CNN.

A "poor" rating does not necessarily mean a bridge is at risk of collapsing, according to the American Society of Civil Engineers, but it does mean they should be inspected regularly. The collapsed bridge was inspected last September, the city's fire chief told reporters.

Biden's $1 trillion infrastructure spending package https://www.reuters.com/world/us/roads-bridges-airports-details-bidens-1-trillion-infrastructure-bill-2021-11-05, the largest such investment in decades, is already providing billions of dollars for upgrades to bridges, roads and transit.

The Transportation Department announced earlier this month that it was distributing $5.3 billion to states for bridge repair, a dramatic increase over previous years.

Pennsylvania got the third-largest share, a total of $327 million.

That money will come in handy.

Roughly 11% of the Northeastern state's 30,000 bridges are assessed as being in poor condition, according to a Department of Transportation database, nearly twice the national average. Those bridges handle 5% of daily traffic in Pennsylvania.

The state's bridges were given a grade of D-plus by the engineering society in a 2018 report. Its roads and sewer, water, and transit systems also received low marks.

The society said the state had made progress since approving a fuel-tax hike in 2013 to fund repairs. The group praised Pennsylvania's bridge-inspection program, which it said exceeded federal standards.

Pittsburgh, a post-industrial city of about 300,000 people located at the confluence of three major rivers, is known for its steep hills and scenic bridges. City officials have pressed the Transportation Department to make it easier to lower speed limits https://www.reuters.com/world/us/cities-plea-biden-help-us-lower-speed-limits-2021-06-30 and improve pedestrian safety.
