Washington, April 1 : US President Joe Biden has announced a massive plan to modernise infrastructure, including the largest jobs programme the country has seen since World War II. The approximately $2-trillion package is a "once-in-a-generation investment in America, unlike anything we've seen or done," Biden said on Wednesday in Pittsburgh, in the state of Pennsylvania, DPA news agency reported. The plan is expected to "create millions of good jobs," with the White House comparing the size of the investment to when America "won the space race." Biden said the plan was necessary to position the US to "out-compete China," emphasizing that "we have to do it." The package includes the modernization of around 32,000 km of roads, 10,000 bridges, more airports, and electric mobility. Part of the programme is also dedicated to improving the quality of "crumbling" water systems, electrical grids, high-speed Internet and to quality housing. "Put simply, these are investments we have to make," Biden said. "Put another way, we can't afford not to." Biden will need to push the plan through the US Congress. During the election, the Democrats had spoken in favour of a large package to improve infrastructure. However, for the adoption of such a package, the president will need the approval of around 10 Republicans. Senate Republican Minority Leader Mitch McConnell immediately rejected the plan. /IANS
