The historic frontier of Magic Kingdom is echoing with the sounds of crunching timber and heavy diesel engines. The days of taking a peaceful raft over to Tom Sawyer Island are officially gone, replaced by the largest geographical overhaul in the parkโs 55-year history.

As we cross the midpoint of May 2026, construction on the highly anticipated Piston Peak National Parkโthe Cars-themed expansion taking over Frontierlandโhas officially shifted into high gear. Recent field updates from @bioreconstruct reveal a bittersweet reality: Disney has completely leveled a piece of 1971 opening-day history to clear the way for massive concrete foundations that are permanently rewriting the park's map.
The Extinction of the Mike Fink Keel Boat Landing
For casual guests walking past Liberty Square, the rustic wooden structure on the waterโs edge was just a charming backdrop. But for Disney purists, the Mike Fink Keel Boat Landing was a sacred piece of opening-day history.
Welcoming its first guests on October 1, 1971, the water attraction allowed visitors to board free-floating wooden keel boats inspired by Disneyโs classic 1950s Davy Crockett television episodes. While the actual boats were permanently retired in 2001, the loading dock and its overhead wooden pavilion stood completely intact for another 25 years, serving primarily as an extended overflow queue line for The Haunted Mansion during peak holiday seasons.
That history has officially met the excavator. Recent construction updates reveal that demolition crews have completely leveled the structure. The rustic wooden docks have been pulled from the riverbanks, leaving a wide, open gap along the stone embankment.
Why Clear the Landing?
While it is always tough to see an original 1971 asset destroyed, this clearing serves a vital master planning purpose:

- The High-Capacity Artery: The cleared footprint is being repaved and heavily widened into a massive guest thoroughfare.
- The Gateway to the Future: This pathway will serve as the primary artery, funneling heavy foot traffic out of Liberty Square and directly into the entrances of both the new Cars Land and the upcoming Villains Land, located beyond the frontier.
Aerial Views Reveal Massive Curved Retaining Walls
Looking deep into the completely drained, dusty basin where millions of gallons of water once sat, aerial imagery from @bioreconstruct highlights incredible structural milestones. The most prominent features now dominating the center of the 4.5-acre construction zone are massive, curved concrete retaining walls.
These heavy-duty concrete barriers are snaking directly through what used to be the water channel separating Liberty Square from Tom Sawyer Island. Backed by thousands of tons of freshly graded earth and reinforced with steel rebar, these walls serve a critical dual engineering purpose:
- Soil Reinforcement: They act as structural shields, keeping the elevated guest walkways completely secure.
- Shaping New Water Features: These concrete curves define the exact boundaries for the new, smaller river configurations and artificial waterfalls that will weave through the national park environment, replacing the massive footprint of the old riverbed.
Digging the Sunken Rally Tracks
The latest aerial schematics reveal that Walt Disney Imagineering is using dramatic elevation shifts to pull off a classic optical illusion. The center of the former river basin has been excavated significantly deeper than the original riverbed, creating a deeply sunken valley right in the middle of the site.

This low-lying zone will host the primary mechanics of the land's flagship off-road rally attraction. By burying the ride tracks deep into the ground and building towering artificial canyon walls around them, Imagineers are ensuring that the high-tech car architecture remains completely hidden from the 19th-century colonial sightlines of Liberty Square until you are fully immersed within the landโs boundary.
The Road to Grand Opening
To protect guest immersion while this massive construction pit operates at full capacity, Disney recently finalized a massive perimeter barrier along the northern edge of Big Thunder Mountain Railroad. The classic roller coaster recently emerged from a lengthy refurbishment, and riders are now greeted by towering, rough-hewn wooden construction panels lining the low-lying sections of the track.
While it blocks the view from the ground, guests climbing the coaster's highest lift hills are still treated to an expansive, unobstructed bird's-eye view of the project.

With the foundation phase advancing at aggressive momentum, vertical steel framing for the primary mountain structures is expected to pierce the Magic Kingdom skyline by late 2026 or early 2027. Barring any major changes, a realistic grand opening for this massive Cars extension is currently targeted for late 2028 or mid-2029. The frontier is changing forever, and the concrete foundations are officially set.




I would love to see the Rivers of America be rebuilt, left of Big Thunder.
