How Trump drafted renovation plans for Dulles, a "terrible airport"

As he fiddled with ideas earlier this year for how to rejuvenate Washington Dulles International Airport, the capital's aging federally owned airport, President Trump asked a handful of the design and engineering firms competing for the contract to create three-dimensional models so that he could better picture the designs, multiple sources told CBS News.

The hefty tabletop models were taken back and forth to the White House multiple times for the president's perusal and his edits to plans for the terminal transport buses, parking lot location, baggage handling system, underground trains and general airport aesthetic, sources told CBS News.

This week, Mr. Trump intends to publicly reveal his plans, two of the sources said. He was scheduled to make a formal announcement Wednesday from the Oval Office with Transportation Secretary Sean Duffy, but the timeline could shift.

Mr. Trump has called Dulles a "terrible airport" that "was incorrectly designed." Privately, the president has vented about "parking that's two miles away" and has called the current mobile lounge transportation system "crazy," sources told CBS News.

It's the latest makeover the president has dabbled in during his second term, after the White House East Wing and new ballroom, Kennedy Center, and various parks in Washington.

His preferred that the new Dulles design preserve the iconic sloped-roof main terminal, designed by Eero Saarinen, but would refurbish the interior with an open foyer and new ticket kiosks for the airlines, one of the sources said.

The $22.5 billion renovation will scrap the mobile lounges, colloquially called "people movers" and arguably the most unpopular component of the international airport. They have been used at Dulles since 1962.

A new underground U-shaped aerotrain will bring travelers to their terminals, along with moving sidewalks. The existing aerotrain only serves the A, B and C concourses, and not the D concourse where the United Airlines gates are located. More moving sidewalks are also going to be added.

The plans include a major terminal expansion: Four new linear concourses where the current A, B, C and D gates are. The C and D gates, constructed in 1985, were meant to be temporary terminals for United Airlines but have remained in place for over 40 years.

The new design will move the parking lot closer to the main terminal for travel convenience.

In recent months, Mr. Trump hosted charrettes, calling in executives from development and finance companies to the Oval Office to make pitches, and he hounded his advisers by phone with suggestions
