It’s been a while since I flew through SLC, so when I flew through last week, I noticed right away that there were some extra concourses nearly on top of the existing terminals.
It turns out that SLC is building a pair of replacement concourses on the site of the existing concourses. It looks like their intent will be to move existing flights from the existing concourses C/D/E/F/G to the new concourses A and B, tear down C/D/E/F/G, and then possibly expand A and B to the east.
Because of the work in progress, for the first time, I’ve created two terminal silhouettes in the same drawing – the old terminal before any construction started (circa 2015), and the combined site with both the old and new facilities intertwined. I suspect I’ll eventually also add the final configuration to this image once construction is complete, and perhaps some more intermediate steps if I can find appropriate reference materials.
