How Trump should spend $1 trillion on America's infrastructure, according to architects and urban planners

In late January, Donald Trump will become the president of the United States. One major piece of his plan for the new administration is spending $1 trillion on infrastructure.

Released in October, Trump's infrastructure plan outlines his administration's policy wishes for things like water systems and transportation for the next four years.

If approved by Congress, it will be the largest infrastructure package in a decade.

Trump budgets $1 trillion largely for highway, waterway, airport, pipeline, and bridge projects. Emphasizing $140 billion in tax cuts to private-sector investors, it "is in the proud tradition of President Dwight D. Eisenhower, who championed the interstate highway system," his campaign writes.

Business Insider asked a number of architects and urban planners for their recommendations on how Trump's administration should spend the $1 trillion.

Here are some of the projects they'd like to see.
