U.S. Congress on Friday passed a US$1 trillion package of highway, broadband and other infrastructure improvement, sending it on to President Joe Biden to sign into law.

The 228-to-206 vote is a substantial triumph for Biden’s Democrats, who have bickered for months over the ambitious spending bills that make up the bulk of his domestic agenda.

Biden’s administration will now oversee the biggest upgrade of America’s roads, railways and other transportation infrastructure in a generation, which he has promised will create jobs and boost U.S. competitiveness.

Democrats still have much work to do on the second pillar of Biden’s domestic program: a sweeping expansion of the social safety net and programs to fight climate change. At a price tag of US$1.75 trillion, that package would be the biggest expansion of the U.S. safety net since the 1960s, but the party has struggled to unite behind it.

Democratic leaders had hoped to pass both bills out of the House on Friday, but postponed action after centrists demanded a nonpartisan accounting of its costs – a process that could take weeks.

The infrastructure bill passed with the support of 13 Republicans, fulfilling Biden’s promise of passing some bipartisan legislation. The phrase “infrastructure week” had become a Washington punch line during his predecessor Donald Trump’s four years in the White House, when plans to focus on those investments were repeatedly derailed by scandals.

“Generations from now, people will look back and know this is when America won the economic competition for the 21st Century,” Biden said in a statement.

The party is eager to show it can move forward on the president’s agenda and fend off challenges in the 2022 midterm elections in which Republicans will seek to regain control of both chambers of Congress, which they lost to the Democrats under Trump.

Congress also faces looming Dec. 3 deadlines to avert a politically embarrassing government shutdown and an economically catastrophic default on the federal government’s debt.

With razor-thin majorities in Congress and a united Republican opposition, Democrats need unity to pass legislation.
