A's Las Vegas Ballpark Hits New Heights: Third and Tallest Roof Truss Arch Is Up on the Strip

FRIDAY, OCTOBER 9, 2026 — You can finally see the shape of the thing. The Athletics confirmed this week that the third steel roof truss arch is complete at their new Las Vegas ballpark, and with it, the project has reached its tallest point — a steel arc roughly 290 feet above the field, visible from all over the south Strip. It's the kind of milestone that turns a construction site into a skyline. And it's not just the steel: the luxury steakhouse behind home plate is already sold out for 2028, three out of four buyers are locals, and downtown's Circa just signed on as the team's official resort and sportsbook. The ballpark isn't just going up. It's starting to feel like Vegas.

The milestoneThe third truss is up — and it's the tallest one

The official Athletics account posted the update on X on October 8: "Checking off another major milestone! This week, crews completed the installation of the third and tallest steel truss arch at our future ballpark," as reported by ClutchPoints. The Review-Journal, which has tracked every truss lift at the Tropicana site, said the completion marked the tallest point of the $2.1 billion stadium.

For context on how fast this is moving: the first roof truss was installed only a few months ago, the second was completed in mid-August, and now the third — the one that establishes the roofline's high point — is locked in. According to Ballpark Digest, the third steel truss supporting the roof is now in place, continuing a steady drumbeat of construction updates as the project pushes toward its 2028 opening.

These arches are the skeleton of the whole design. The roof is made up of five overlapping shell structures meant to look like baseball pennants, carried on freestanding steel arch trusses that span nearly 700 feet across the playing field, as reported by ClutchPoints. At its peak, the tallest arch rises 290 feet above the field — taller than the MGM Grand tower across the street. When drivers land at Harry Reid Airport, as A's president Marc Badain put it over the summer, the ballpark will be "certainly the first building you see," per theScore's report of his August remarks.

The buildingWhat $2 billion buys you

The ballpark is being designed by the Bjarke Ingels Group (BIG) in partnership with HNTB, and it sits on nine acres between Tropicana Avenue and Reno Avenue — the old Tropicana Las Vegas site, directly on the Strip, per ClutchPoints. The project carries an estimated cost of roughly $2 billion and will seat about 33,000 spectators, making it the smallest ballpark in Major League Baseball but one of the most decked-out.

The design is deliberately not a traditional ballpark dropped onto the Strip. The exterior is meant to visually blend with the resort corridor rather than stand apart from it, and the metal cladding is expected to reflect both daylight and the city's nighttime lighting so the building changes character from day to night, according to ClutchPoints. The showpiece is the outfield: one of the world's largest cable-net glass walls, offering panoramic views of the Las Vegas skyline and surrounding resorts while fans watch the game. Instead of blasting air conditioning from overhead, the dome will push cool air closer to the seats — a practical touch for desert summers.

Construction is being run by a Mortenson-McCarthy joint venture, with Thornton Tomasetti serving as the structural engineers on the project. And the A's aren't waiting until 2028 to play ball — the team continues to play home games at Sutter Health Park in West Sacramento until the move is complete.

The Vegas wayThe steakhouse sold out. The locals bought it. Circa's in.

Here's the part that tells you this building is going to be very Las Vegas. Ballpark Digest reports that the team's new high-end restaurant, the Athletic Club — an all-inclusive steakhouse, supper club, and lounge behind home plate with a private entrance and a speakeasy theme — is already sold out for the 2028 debut. It will seat 290 and open only to the highest-end season-ticket holders and their guests.

But the sellout isn't the interesting part. The buyers are. "What stands out most about the response to the Athletic Club is not just that it sold out, but also who is buying it," Athletics president Marc Badain said in a statement, per Ballpark Digest. "Three out of every four buyers are from Southern Nevada, and nearly 70% are individuals rather than businesses." Around 76 percent of the buyers are from Southern Nevada. For a city that spent years wondering whether locals would actually embrace the A's, a sold-out steakhouse full of locals is a pretty loud answer.

And then there's the partnership news, also from Ballpark Digest: Circa is now one of 10 to 12 ballpark founding partners, and the deal names the downtown hotel-casino the "Official Resort and Sportsbook of the Las Vegas Athletics," according to Ballpark Digest. Circa will host two entertainment areas inside the ballpark: 22 seats in the Circa Dugout Club right next to a dugout, plus a 28-capacity area in the outfield. Circa is owned by Derek Stevens, a former owner of the Las Vegas 51s, the Triple-A team that used to play here — and as Ballpark Digest notes, he's been one of the biggest investors in downtown Vegas, where Circa, the city's largest sportsbook, anchors the east end of Fremont. For a ballpark that will physically sit next to a Bally's resort, giving downtown's crown jewel the official sportsbook slot is a statement about whose Vegas this ballpark is for.

The timelineOn time, on budget, Opening Day 2028

Zoom out and the pattern is unmistakable: this project keeps hitting its dates. Less than a year after breaking ground, bowl steel for the entire structure went up in roughly three months. By June the steel framing had reached the third and fourth levels, the concourse ring was a complete unbroken circle, and the first roof truss arch was locked in. The second truss followed in August. Now the third — the tallest — is done, and the workforce is expected to surge from roughly 650 craft workers to well over 1,300 once all the trusses are up and roof panels start going on.

Badain has said all along the ballpark stays on schedule for the 2028 season, and at this point the skyline agrees with him. Sports has the full Friday guide here, and we'll keep tracking every truss lift until the pennants take shape. The Vegas Daily roundup has the rest of today's city news. Opening Day 2028 is still a year and a half away. The hard part is done believing. Now we just get to watch it rise.
