View Comments U.S. Secretary of Transportation Pete Buttigieg visited Pittsburgh on Thursday afternoon to take a close look at some bridges and tout the infrastructure benefits in President Joe Biden’s American Jobs Plan. During a press conference on Mt. Washington overlooking the city, Buttigieg called for a “generational investment” through the $2.6 trillion American Jobs Plan to fix the nation’s infrastructure, much of it aging like the bridges, and locks and dams along Pittsburgh’s famous three rivers, the Monongahela, Allegheny and Ohio. Buttigieg noted Pittsburgh’s industrial history and how those workers a century ago helped produce the steel that built many of the 446 bridges that dot the city.
