The measure is designed to create jobs across the country by dispersing billions of dollars to state and local governments to fix crumbling bridges and roads and expanding broadband internet access to millions of Americans.
The bill-signing ceremony, held in chilly weather on the White House South Lawn to accommodate a big crowd, was an increasingly rare moment when members of both parties were willing to stand together and celebrate a bipartisan achievement. Biden, whose job approval ratings have dropped because of his handling of the economy and other issues, heard supportive chants of "Joe, Joe, Joe" from some in the crowd and got a standing ovation as he stepped to the microphone.
Biden said the bill's passage showed that "despite the cynics, Democrats and Republicans can come together and deliver results."
Republicans attending included Senator Rob Portman of Ohio, Senator Mitt Romney of Utah and Maryland Governor Larry Hogan.
