Salt Lake City International Airport held a “topping out” ceremony Wednesday for its new terminal to celebrate the final beams placed there.

Such ceremonies can be traced to Scandinavian rites to place a tree atop a new building to appease the tree-dwelling spirits displaced during Construction.

The new $485 million terminal will cover 866,087 square feet. It used 11,000 tons of structural steel and 22 miles of steel piles. The building will include a 6.2 mile conveyor system for baggage.

The first phase of the terminal replacement project is scheduled to open in fall 2020, with an elevated roadway with one level for dropping off passengers and another for pick-ups. It will have a new parking garage with 3,600 stalls, and one central terminal to replace three existing ones.
