Transportation Secretary Pete Buttigieg on $2.3 trillion infrastructure plan: 'Doing nothing is what's truly unaffordable'

"We're either going to pay now or we're going to pay a lot more later," Buttigieg told ABC News.

Secretary of Transportation Pete Buttigieg didn't hit the road on Thursday, he took to the water in an effort to gain support for the administration's $2.3 trillion infrastructure plan. Buttigieg retuned to Pittsburgh, where the plan was first announced by President Joe Biden in March, to get an up-close look at some of the nation's aging bridges, locks and dams. Pennsylvania has the second-most structurally deficient bridges in the United States, according to the American Road and Transportation Builders Association. Some of the older bridges have to be draped with nets designed to capture pieces of concrete that could plummet to the sidewalk. "We're relying on infrastructure from the last century," Buttigieg told ABC News' Transportation Correspondent Gio Benitez as they traveled by boat down the Ohio River.
