Piston Peak is quietly hitting its milestones. The latest construction update from Magic Kingdom shows that the utility pipes staged around the Cars-themed expansion site have now been buried, another sign that the Frontierland-area project is moving from groundwork to vertical construction.
Why Buried Pipes Matter
It is not the flashiest milestone, but underground utility work is the unglamorous backbone of any Disney expansion. Once water, power, and drainage infrastructure disappears beneath the surface, sites typically shift toward foundations and show building steel, the phase where a project starts to look like something. Photos of the progress were captured by BlogMickey.com, which has been documenting the site’s transformation week by week.
The Cars Expansion Takes Shape
Piston Peak National Park will bring the world of Cars to the area beyond Big Thunder Mountain, part of the largest wave of construction in Magic Kingdom history alongside the villains land project. Between land clearing, the reimagined Rivers of America area, and now buried utilities, the expansion has moved steadily through 2026, and fans are hoping for a construction status update, if not more, when Disney takes the stage in Anaheim next month for the D23 Experiences Showcase.
What To Watch Next
With utilities down, the next visible milestones should be foundation work and the first steel. Given the pace of aerial updates lately, the transformation of this corner of the park is about to get much harder to miss.
