By approving details of America's largest investment in roads and bridges in decades, the U.S. Senate came a step closer to passing a trillion - dollar bill proposed by the Democratic and Republican parties for infrastructure.

After a vote of 69 to 28, the Senate moved to support compromise clauses reached after hard talks by a group of Republicans and Democrats.

This law is a top priority for Democratic President Joe Biden. Its adoption would be a major victory for him and the bipartisan deputies who drafted it.

It should be noted that funding for Biden's initial infrastructure plan exceeded $2 trillion, but that value was reduced after discussions by Democrats and Republicans to just $1 trillion.

White House press secretary Jen Saki said last May that the proposal to cut funding is part of the "art of finding common ground," and shows the Biden administration's willingness to reduce spending, while maintaining "the most vital areas for rebuilding our infrastructure and future industries."

Republicans rejected Biden's proposal for infrastructure not only because of its size, but also because it included a proposal to increase the corporate tax rate from 21 to 28 percent to pay for investments.
