PITTSBURGH — President Joe Biden on Wednesday outlined a $2.3 trillion plan to reengineer the nation’s infrastructure over the next eight years in what he billed as “a once-in-a-generation investment in America.”

Speaking at a carpenters union training center in Pittsburgh, Biden drew comparisons between his hard-hatted proposed transformation of the U.S. economy and the space race — and promised results as grand in scale as the New Deal or Great Society programs that shaped the 20th century.

“It’s not a plan that tinkers around the edges,” Biden said. “It’s a once-in-a-generation investment in America unlike anything we’ve seen or done since we built the interstate highway system and the space race decades ago. In fact, it’s the largest American jobs investment since World War II. It will create millions of jobs, good-paying jobs.”

White House officials say the spending would generate those jobs as the country shifts away from fossil fuels and combats the perils of climate change. It is also an effort to compete with the technology and public investments made by China, which has the world’s second-largest economy and is fast gaining on the United States’ dominant position.

“I’m convinced that if we act now, in 50 years people are going to look back and say this is the moment when America won the future,” Biden said.

Funding for the infrastructure projects would come from a hike on corporate taxes that would aim to raise the necessary piles of money over 15 years and then reduce the deficit going forward. In doing so, Biden would undo the action by Trump and congressional Republicans to lift the corporate tax rate to 28% from the 21% rate set in a 2017 overhaul.

The Democratic president’s infrastructure projects would be financed by higher corporate taxes. Biden hopes to pass an infrastructure plan by summer, which could mean relying solely on the slim Democratic majorities in the House and the Senate.

The White House says the largest chunk of the proposal includes $621 billion for roads, bridges, public transit, electric vehicle charging stations and other transportation infrastructure. The spending would push the country away from internal combustion engines that the auto industry views as an increasingly antiquated technology.

An additional $111 billion would go to replace lead water pipes and upgrade sewers. Broadband internet would blanket the country for $100 billion. Separately, $100 billion would upgrade the power grid to deliver clean electricity. Homes would get retrofitted, schools modernized, workers trained and hospitals renovated under the plan, which also seeks to strengthen U.S. manufacturing.

The new construction could keep the economy running hot, coming on the heels of Biden’s $1.9 trillion coronavirus relief package. Economists already estimate it could push growth above 6% this year.
