Seattle-Tacoma International Airport (SEA) is building a new International Arrivals Facility (the IAF) which has a 708-foot-long aerial walkway as one of its features.
When in place, the walkway will look like this and be the longest structure over an active airport taxiway.
Pretty impressive, right?
But as impressive is what it takes to make the project happen.
For example, overnight on Thursday, the center span of that elevated pedestrian walkway was – very carefully – moved down the closed center runway to its new home.
Here are some of the tweets SEA shared as the process unfolded.
And here is the aerial walkway in place!
