The brand new McDonald’s HQ is poking up through the top of the West Loop.

In one of the most ridiculous comparisons to date, if the new McDonald’s Headquarters being built in the West Loop was a Big Mac, it would be somewhere between the second all-beef patty and the middle bun, with the bottom bun and first patty already in place. That leaves the special sauce, lettuce, cheese, pickles, and onions to go before the top bun is craned into place and sprinkled with sesame seeds.

In more technical terms, The McD HQ is up to the sixth floor, as crews from McHugh Construction continue utilizing two tower cranes to get the nine-story, 550,000-square-foot Sterling Bay development in high gear. The Gensler-designed home of the Golden Arches is slated to open early in 2018, which looks like a sure thing the way progress is going.
