Washington, Nov 16 (TIWN) US President Joe Biden has signed a bipartisan $1 trillio infrastructure bill into law after months of delay amid Democratic infighting over a social spending package.

"Here in Washington, we've heard countless speeches and promises, white papers from experts, but today we're finally getting this done," Biden said Monday at a signing ceremony at the White House attended by members of Congress, governors and mayors.

"So my message to the American people is this, America's moving again, and your life is going to change for the better," he said.

Biden has tapped former New Orleans Mayor Mitch Landrieu as a senior White House adviser to coordinate the implementation of the infrastructure bill.

The bill includes 550 billion dollars in new spending on infrastructure projects, such as roads, bridges, passenger rails, drinking water and waste water systems. The rest of the infrastructure package involves previously approved spending.

The U.S. Senate approved the bill in August. Then progressive House Democrats held up the Senate-passed bill for months, demanding a vote on the larger social spending package, but eventually failed.

The U.S. House of Representatives finally approved the infrastructure bill earlier this month after progressive and moderate House Democrats agreed to take up the 1.75-trillion-dollar social spending package no later than the week of Nov. 15.
