The second truss arch is up at the A's ballpark, and the schedule is still holding
A $2 billion, 33,000-seat stadium on nine acres, with substantial completion set for February 2028. As of the last public update it was on time and on budget — two words that rarely survive a Las Vegas megaproject.
The second of the ballpark's steel truss arches was completed on August 18, 2026. That is the structural signature of the building — the element that will make it recognizable from the freeway — and getting the second one placed is the milestone that matters most this year.
The project is a $2.0 billion ballpark seating 33,000, built on nine acres of a 35-acre South Strip site, with substantial completion targeted for February 29, 2028. The general contractor is a Mortenson–McCarthy joint venture. As of the most recent public reporting, after roughly $400 million of work, the project was described as on time and on budget (Ballpark Digest).
Why nine acres is the interesting number
A 33,000-seat stadium on a nine-acre footprint is a tight build, and tight builds are where schedules go to die. There is limited room for laydown yards, material staging, crane positioning, and trade parking. Every delivery has to be sequenced rather than stockpiled. Placing two large truss arches inside that envelope, on schedule, is a real logistics result and not just a photo opportunity.
It also explains why the arches went up when they did. Heavy structural steel comes before the site gets crowded with interior trades. Once the bowl fills with finish work, the window for that kind of lift closes.
"On time and on budget" is a claim with a date attached. It was true at the last public update. It is not a forecast.
The honest caveat
We are reporting a status, not a guarantee. Substantial completion in February 2028 leaves roughly eighteen months of work, and the phase ahead — enclosure, seating, systems, field, and the entire technology and concessions fit-out — is where cost pressure typically shows up on stadium projects. The right posture is to treat the current schedule as credible and keep checking it.
For scale on what a Las Vegas public project can do to a budget: the I-15 and Tropicana interchange next door finished at $382 million against an original contract award of $305 million — $77 million over (i15trop.com). Different owner, different delivery method, but a useful reminder that final numbers and announced numbers are different animals.
What we are watching
- Enclosure start. The transition from structure to skin is the next real schedule test.
- Any change to the February 29, 2028 substantial completion date. That date is specific enough that movement will be visible.
- Stadium Authority reporting. The public financing structure means there is a paper trail, and we will follow it rather than press releases.
