Virtually no part of the U.S. economy is untouched by the plan chiefly put together by Sens. Rob Portman (R-Ohio) and Kyrsten Sinema (D-Ariz.). Roughly half of its $1 trillion overall price tag constitutes new federal spending, with the rest coming from existing, planned investments in the country’s roads, highways and bridges, according to details released in recent days by lawmakers and the White House, which supports the proposal.

Those thoroughfares would see major expansions and repairs under the bill, which has additional investments in the nation’s transit system as well. Senators also said the measure calls for $66 billion targeting passenger railways, which the White House says is the largest such investment since the creation of Amtrak nearly a half-century ago.

Lawmakers plan to set aside $55 billion to improve the country’s drinking water, including a program that seeks to replace every lead pipe in America. There’s an additional $65 billion to expand broadband Internet access nationwide and ensure those who do have connectivity can afford their monthly payments. And Senate lawmakers are pursuing additional sums to upgrade key commercial hubs, including potentially $25 billion for repairs at major airports.
