WASHINGTON — The Senate is expected on Tuesday to pass a $1 trillion bipartisan infrastructure package, capping off weeks of intense negotiations and debate over the largest federal investment in the nation’s aging public works system in more than a decade.
The legislation, which still must pass the House, would touch nearly every facet of the American economy and fortify the nation’s response to the warming of the planet.
It would greatly increase funding to modernize the nation’s power grid and finance projects to better manage climate risks, and it would devote hundreds of billions of dollars to repair and replace aging public works projects. The legislation was largely negotiated by a group of 10 Senate Republicans and Democrats and White House officials.
Nearly 70 senators from both parties voted to advance the measure over the weekend toward the final vote Tuesday, which is scheduled for 11 a.m. Despite criticism from former President Donald J. Trump, many Republicans, including Senator Mitch McConnell of Kentucky, the minority leader, were poised to embrace federal aid for their states.
But as soon as the bill clears the Senate, Democrats are expected to take up a $3.5 trillion budget blueprint that will unlock their ability to muscle through an expansive social policy package over unanimous Republican objections.
Under the fast-track budget reconciliation process, that blueprint, if passed with a simple majority, will dictate the parameters of a transformative package expected to provide funding for health care, climate change, education and child care, and to increase taxes on wealthy people and corporations.
The budget can pass, however, only after a marathon of rapid-fire votes, known as a vote-a-rama, that is expected to stretch at least through midnight Wednesday.
