Following months of delays and legislative maneuvering, President Joe Biden signed the $1.2 trillion bipartisan infrastructure bill into law Monday, notching a significant political victory amid slumping polls and an uncertain future for other elements of his agenda.

“For too long, we’ve talked about having the best economy in the world,” Biden said in his prepared remarks. “We’ve talked about asserting American leadership in the world with the best and safest roads, railways, ports, and airports. Here in Washington, we’ve heard countless speeches, promises, and white papers from the experts. But today, we are finally getting it done.”

The Infrastructure Investment and Jobs Act, which passed the Senate in August and the House earlier this month, allocates roughly $1.2 trillion over 10 years for a wide variety of infrastructure projects. About $550 billion of that total is new spending, with the rest representing a renewal of expected funding.

The new spending is divided into $284 billion for surface transportation – which includes roads and bridges, rail, airports, ports, public transit and electric vehicles – and $266 billion for core infrastructure, which includes the power grid, broadband services, water systems and environmental resiliency. Some highlights:

* $73 billion to upgrade the nation’s electrical grid;

* $66 to improve Amtrak rail service;

* $65 billion for broadband internet service, with an emphasis on access in rural areas;

* $47 billion to improve resistance to fires, hurricanes and floods;

* $21 billion for environmental clean-up projects overseen by the Environmental Protection Agency;

* $15 billion to remove lead pipes in municipal water systems;

* $7.5 billion for electric vehicle infrastructure.

Some of the spending will be offset by revenue sources, including $200 billion in unused Covid-19 relief spending and about $50 billion in unemployment benefit funds returned by the states, but the offsets will not cover the full cost. According to the Congressional Budget Office, the infrastructure package will add $256 billion to the federal deficit over the next 10 years.

A bipartisan effort: Lawmakers from both parties attended the signing ceremony on the White House lawn, including key negotiators Sens. Kyrsten Sinema (D-AZ) and Rob Portman (R-OH), and the president said that the passage of the bill is “proof that despite the cynics, Democrats and Republicans can come together and deliver results.”

Still, the votes on the bills were lopsided, with all but a handful of Democrats voting yes and the majority of Republicans voting no. In the Senate, 19 of 50 Republicans supported the bill, while just 13 out of 213 Republicans in the House did so – and they have faced a backlash for their bipartisan cooperation.
