A report card from an engineering group found that American roads, ports and other infrastructure got better last year but could be hurt if federal funding is reduced.
Increased federal spending in recent years has helped to improve U.S. ports, roads, parks, public transit and levees, according to a report released on Tuesday by the American Society of Civil Engineers.
But that progress could stagnate if those investments, some of which were put on hold after President Trump took office in January, aren’t sustained.
Overall, the group gave the nation’s infrastructure a C grade, a mediocre rating but the best the country has received since the group’s first report card in 1998. Most infrastructure, including aviation, waterways and schools, earned a C or D grade; ports and rail did better. The group also projected a $3.7 trillion infrastructure funding shortfall over the next decade.
“The report card demonstrates the crucial need for the new administration and Congress to continue sustained investment in infrastructure,” Darren Olson, the chairman of the society’s committee on America’s infrastructure, said on a call with reporters. “Better infrastructure is an efficient investment of taxpayer dollars that results in a stronger economy and prioritizes American jobs.”
The report, which is now released every four years, has long noted that the United States spends too little on infrastructure. But that started to change in 2021, the group said, thanks to the Infrastructure Investment and Jobs Act, which authorized $1.2 trillion in funding under President Joseph R. Biden Jr. That investment is showing results, with grades having improved since the last report, in 2021, for nearly half the 18 categories that the group tracks.
But in January, Mr. Trump froze much of the funding under that law and another aimed at addressing climate change, pending a review by his agencies. That halted a variety of programs, including those intended to help schools, farmers and small businesses.
