Frontierland Rebuild Advances With Grading and New Infrastructure at Magic Kingdom

Fresh photos confirm the former river basin is being recontoured with early construction underway for Piston Peak and an adjacent Villains area.

Overview

  • Crews are actively lowering the former Tom Sawyer Island and grading the ex–Rivers of America basin to match surrounding terrain.
  • Stacks of lumber, a shipping container, and other equipment are staged in the zone slated for the Cars-themed Piston Peak National Park.
  • Freshly poured themed pavement has appeared near the Big Thunder Mountain Railroad exit after a temporary structure was removed.
  • Big Thunder Mountain Railroad remains closed for refurbishment, with trains testing and a spring 2026 reopening expected.
  • Tree removal behind It’s a Small World shows the project footprint extending beyond the old river area, and Disney has not announced opening dates for the new lands.
