how long will the big arch be available

McDonald’s Big Arch burger is being offered as a limited‑time item in the U.S., and McDonald’s hasn’t announced an exact end date yet, so expect it to be around for only a short run (likely weeks, not all year) before it disappears again.

How long will the Big Arch be available?

Most official and news sources describe the U.S. Big Arch as:

• A nationwide launch starting March 3 at participating locations.

• Clearly labeled a “limited time” offer with no official last day published.

• Sold only during the regular day menu (after breakfast) and “while supplies last,” meaning some stores can sell out earlier on busy days.

In past test markets like Canada and some European countries, forum posts suggest the Big Arch stuck around for just a couple of months before being pulled, even where people expected it to be longer. That history reinforces that this U.S. run is likely short-lived and not guaranteed to become permanent.

What about outside the U.S.?

• In the U.K. and Ireland, McDonald’s has announced the Big Arch as a permanent menu item from early January, saying “it’s back and it’s here to stay,” so it’s not limited there for now.

• In earlier launches like Canada and Portugal, users on fast‑food forums report that it was removed after a promotional window because a double burger was “too big” for typical demand and didn’t sell enough, despite strong fan reviews.

So the answer depends a lot on where you are: permanent in the U.K./Ireland (for now), but explicitly limited‑time in the U.S.

Practical tips if you want to try it

• Go sooner rather than later: Since McDonald’s has not given an end date and is calling it limited‑time, it could end with the next promo cycle (often 4–8 weeks for big LTOs). This isn’t official, just consistent with how similar promos work.
• Check your local app or store: Some locations add it a bit early or keep stock a bit longer, but once it disappears from your local menu or app, it’s usually gone.
• Watch for future returns: In markets where it did well, there’s precedent for McDonald’s bringing the Big Arch back, and in the U.K./Ireland it’s already been upgraded to a standing menu item.
