Disneyland Just Hit a MAJOR Construction Milestone on Two New Marvel Rides—And Cast Members Are Already Part of History

If you have been watching the construction walls go up around Avengers Campus at Disney California Adventure, we have some news that will get you excited. Disney just reached a significant construction milestone on two highly anticipated Marvel attractions, and the ceremony that marked the occasion means dozens of cast members will forever be part of these rides’ legacy.

On February 6, 2026, Disney invited cast members to participate in a time-honored construction tradition: signing a steel beam that will be placed at the highest point of the new Avengers Campus expansion building. According to Cinemablend, this beam signing ceremony represents a major step forward for the two new attractions under construction—Avengers Infinity Defense and Stark Flight Lab.

The ceremony took place behind construction walls, away from guest view, but its significance cannot be overstated. Cast members who participated added their autographs and personal messages to the steel beam before it was raised into place at the building’s peak. These signatures will remain hidden within the structure for decades to come, creating a permanent connection between the cast members and these groundbreaking new attractions.

What This Milestone Means for Construction Progress

Reaching the “topping off” point—when the highest structural element is put in place—is a critical milestone in any construction project. It signals that the vertical construction phase is essentially complete, and the project is transitioning to the interior build-out and finishing stages.

For the Avengers Campus expansion, this means the building’s skeleton is now in place. While there is still substantial work ahead—including installing ride systems, theming, special effects, and all the intricate details that make Disney attractions so immersive—the structure itself has reached its full height.

Construction observers have noted visible progress in recent weeks. The building housing both Avengers Infinity Defense and Stark Flight Lab is now almost fully enclosed, with the roof nearly complete. This rapid vertical progress suggests Disney is making the expansion a priority, though an official opening date remains elusive.

Meet the Two New Attractions

While Disney has been relatively tight-lipped about specific details, we know that two distinct attractions are being built as part of this Avengers Campus expansion.

Avengers Infinity Defense is the headliner—an E-ticket attraction that promises to be a major draw for the park. Based on concept art and insider reports, this ride will transport guests into a multiverse adventure where Marvel heroes from across different realities team up to battle King Thanos. The ride system appears to be based on the same trackless technology used in Tokyo DisneySea’s Peter Pan’s Never Land Adventure, suggesting a highly immersive, dynamic experience where ride vehicles can move independently and create unique paths through the attraction.

The scale of this attraction alone indicates it will be one of Disney California Adventure’s marquee experiences. E-ticket rides represent the highest tier of Disney attractions—think Rise of the Resistance or Radiator Springs Racers—so expectations are understandably sky-high.

Stark Flight Lab represents the second attraction in the expansion, and while it may be physically smaller than Infinity Defense, it promises to deliver a unique experience. This ride will use an innovative twist on the Kuka arm technology—a robotic arm system that can pick up ride vehicles from a track, shake and maneuver them in dynamic ways, and then set them back on the track.

Perhaps most exciting for longtime Marvel fans, Robert Downey Jr. is reportedly returning to voice Tony Stark for this attraction. Given Downey’s retirement from the role in the Marvel Cinematic Universe, his involvement in Stark Flight Lab represents a special opportunity for fans to experience the iconic character in a new medium.

When Can We Ride These Attractions?

Here is where things get frustrating for eager Marvel fans: Disney has not announced any official opening date or even a target season for these attractions.

Based on the current construction timeline and the February 2026 beam signing milestone, a late 2026 opening seems theoretically possible but unlikely. More realistically, we are probably looking at a 2027 debut for Avengers Infinity Defense and Stark Flight Lab.

Several factors support this timeline. First, even though the building structure is now topped off, Disney attractions require extensive interior work. Ride systems must be installed and tested, elaborate theming needs to be constructed, audio-animatronics must be programmed, special effects have to be calibrated, and cast members need training time before opening.

Second, Disney typically does not rush major attraction openings. The company prefers to take the time necessary to ensure everything works flawlessly and meets their exacting standards. Given the technical complexity of both attractions—particularly the innovative ride systems—extensive testing and adjustment periods are almost certainly built into the schedule.

Third, Disney has not included these attractions in any official 2026 marketing materials or event calendars, which usually indicates they are not expecting to open them this year.

What This Means for Your Disneyland Trip

If you are planning a Disneyland vacation in 2026, do not expect to ride these new Marvel attractions. The current Avengers Campus area, which opened in 2021, will still offer WEB SLINGERS: A Spider-Man Adventure and the Guardians of the Galaxy – Mission: BREAKOUT! experience, along with meet-and-greets with Marvel characters and themed dining at Pym Test Kitchen.

However, if you are flexible with your travel dates and can wait until 2027, these new attractions will almost certainly be worth the patience. The combination of cutting-edge ride technology, immersive Marvel storytelling, and Disney’s attention to detail should result in two must-do experiences.

For annual passholders and locals, the wait will likely feel even longer, as you watch construction progress from outside the walls knowing that a multiverse adventure awaits on the other side. The good news is that Disney’s track record with major Marvel attractions has been strong—WEB SLINGERS and Guardians of the Galaxy have both been hits with guests—so there is every reason to believe Avengers Infinity Defense and Stark Flight Lab will deliver.

One thing to keep in mind is that when these attractions do open, expect massive crowds. Major new ride openings at Disneyland typically result in multi-hour waits, and given the popularity of the Marvel brand and the anticipated quality of these experiences, we would not be surprised to see 3-4 hour waits in the opening months. If you are not a fan of long lines, you might want to wait 6-12 months after opening for the initial hype to settle down.

The Bigger Picture for Disney California Adventure

These two new Marvel attractions represent Disney’s continued investment in Disney California Adventure and the Avengers Campus area specifically. When the current Avengers Campus opened in 2021, it was somewhat limited in scope—essentially one major ride (WEB SLINGERS), a relocated attraction (Guardians of the Galaxy), character experiences, and food offerings.

Adding two significant new attractions will transform Avengers Campus into a more complete land, giving guests more reasons to spend time there and creating a Marvel experience that can compete with other major themed areas in Southern California parks.

It also signals Disney’s confidence in the Marvel brand’s appeal within the parks. Despite some fans’ concerns about Marvel not fitting the “Disney” aesthetic, the Avengers Campus has proven popular with guests, and these expansion attractions represent a doubling down on that investment.

For Disneyland Resort as a whole, these additions come at a time when Disney is aggressively expanding and updating its California parks to compete with Universal Studios Hollywood and the looming presence of other theme park competitors. Every new E-ticket attraction helps maintain Disneyland’s position as the premier theme park destination in Southern California.

The beam signing ceremony might have been invisible to guests walking through Disney California Adventure, but it represents a tangible step forward toward two attractions that could redefine the Marvel theme park experience. While we still have a considerable wait ahead before we can step inside Avengers Infinity Defense or strap into Stark Flight Lab, at least we now know construction has reached a significant milestone.

For the cast members who signed that beam, they have secured their place in Disneyland history. Long after they have moved on to other roles or retired, their signatures will remain inside that building, hidden but permanent, connecting them forever to the adventures countless guests will experience in the years to come.

As construction continues, we will be watching closely for any updates on opening timelines, additional details about the ride experiences, or soft opening opportunities. Until then, we can take comfort in knowing that progress is being made, beams are being signed, and the multiverse adventure is getting closer to reality with each passing day.
