The measure provides $US400 billion for $US1400 direct payments to most Americans, $US350 billion in aid to state and local governments, an expansion of the child tax credit and increased funding for vaccine distribution. Forecasters expect it to supercharge the US economic recovery.

"Help is here," Biden wrote in a tweet after the vote on Wednesday. The White House said he plans to sign the bill on Friday.

Approval by a 220-211 vote in the Democratic-controlled chamber came with zero Republican support after weeks of partisan debate and wrangling in Congress. Democrats described the legislation as a critical response to a pandemic that has killed more than 528,000 people and thrown millions out of work.

"This is a historic day. It is the beginning of the end of the great COVID depression," Democratic Representative Jan Schakowsky said.

Republicans said the measure was too costly and was packed with wasteful progressive priorities. They said the worst phase of the largest public health crisis in a century has largely passed and the economy was headed towards a rebound.

"It's the wrong plan at the wrong time for so many wrong reasons," Republican Representative Jason Smith said.

Democrats were eager to get the final bill to Biden's desk for his signature before current enhanced federal unemployment benefits expire on March 14.

The House rejected an effort by Republican Representative Marjorie Taylor Greene to delay proceedings by asking for an adjournment - something she has attempted four times since taking office in January.

The House voted 235-149 to plough ahead, with 40 Republicans joining Democrats in rejecting Greene's effort.

Although many Republicans supported coronavirus relief under former president Donald Trump's administration, no Republican lawmaker voted for the bill in the House or Senate.

But the bill is popular with the public. A Reuters/Ipsos national opinion poll, conducted March 8-9, showed 70 per cent of Americans support the plan, including majorities of Democrats and Republicans. Among Republicans, five out of 10 say they support the plan, while nine out of 10 Democrats supported it.

The version passed by the Senate in an marathon weekend session had removed a $US15-per-hour federal minimum wage increase by 2025; tightened the eligibility for $US1400 direct payments, capping them at those earning below $US80,000, cut the unemployment insurance payment to $US300 a week from the House's $US400, and targeted some of the state and local government aid to smaller communities.

The massive spending push is seen as a major driver, coupled with a quickening pace of COVID-19 vaccinations and a slowing infection rate, in a rapidly brightening outlook for the nation's economy. The Organisation for Economic Co-operation and Development on Tuesday predicted US growth would top six per cent this year, up from an estimate of about three per cent just three months ago.

With the COVID-19 aid bill completed, attention turns to the next round of major legislation Biden aims to push, including massive infrastructure investments, immigration reforms and climate change initiatives.
