It’s crunch time for Taylor Swiftand Travis Kelce‘s upcoming wedding … and there’s a whole lotta action going down at Madison Square Garden … with cargo trucks making important deliveries.

Check out these photos … a massive truck rolled up to the famous arena early Monday, unloading a mountain of black equipment cases and lighting gear — the kind of setup that’s 100% screaming major event … even by MSG’s standards!

Security was everywhere, with workers bustling behind barricaded entrances.

It’s shaping up to be a huge wedding party July 3 at MSG.

As we told you, the “massive stage” secretly being built at a Pennsylvania production facility — which was connected to both Taylor’s Reputation Tour and Eras Tour — is set to be delivered tomorrow.

As for the gear delivered today, MSG’s calendar is pretty quiet until Jon Bon Jovi takes the stage on July 7 … so all signs are pointing towards Tay and Trav’s big day!

Meanwhile, wedding guests are still in the dark just like everyone else … they’ve simply been instructed to be in New York on Thursday, July 2, and Friday, July 3 … and the wedding invitation specifically mentions “in the evening” on July 3.
