Fulfilling one of his campaign promises, US President Donald Trump will uncover his plan for rebuilding the country’s infrastructure this week. The plan will cost US taxpayers $1.5 trillion, but is heavily dependent on state and local funding sources.

The plan will centerpiece a $200 billion pledge from the federal government which will be used to leverage money from cities and state budgets which will earmark them to roads, highways, ports, airports and more.

“Every federal dollar should be leveraged by partnering with state and local governments and — where appropriate — tapping into private sector investment to permanently fix the infrastructure deficit,” Trump said at last month’s State of the Union address.

Trump has said many times that the deteriorating roads and highways are holding the country back from faster expansion of the economy. Some lawmakers and others say that this issue should have been dealt with last year and Trump’s first big push in Congress, instead of the health care issue. Infrastructure is a bipartisan issue that would have helped create a more unified Congress.

The plan was previewed by administration officials as containing two key components: funding for new investments which will help speed up repairs on crumbling roads and airports; and a more efficient way for projects to get the permits they need, so projects can get underway faster. The officials added that the $200 million will come from cuts in other programs.
