WASHINGTON—The U.S. House cleared a $1.2 trillion physical infrastructure bill and took a major step toward passage of a landmark $1.85 trillion social spending and climate bill late Friday, following months of wrangling between Democrats’ progressive and moderate wings.

The votes marked a milestone in the marathon negotiations among members of the House Democratic caucus—and finally victory in sending billions of new dollars in roads, bridge and transit spending to President Joe Biden’s desk. “Tonight, we took a monumental step forward as a nation,” Biden said in a statement issued early Saturday.

“I look forward to signing both of these bills into law,” he said. “Generations from now, people will look back and know this is when America won the economic competition for the 21st Century.”
