Frontierland in Walt Disney World's Magic Kingdom is undergoing significant alterations, with construction walls now surrounding areas like Big Al’s and Westward Ho. Access through a narrow walkway may end soon after the park closes Friday night, based on permits and recent activity. This follows previous closures of Splash Mountain, now Tiana’s Bayou Adventure, and Tom Sawyer Island.
Magic Kingdom's Frontierland, a tribute to the American frontier since the park's 1971 opening, has seen its immersive wooden walkways and open views steadily evolve. Splash Mountain closed and reopened as Tiana’s Bayou Adventure, introducing a Disney film-based theme. Tom Sawyer Island and the Rivers of America shut down for redevelopment into Piston Peak National Park, altering sightlines and spaces that defined the area for decades. Construction walls appeared in mid-April around Big Al’s, a structure from the park's early years, and nearby Westward Ho. Guests have navigated a narrow path to reach these spots, but activity suggests crews may seal it off after Friday night's closure, limiting access for the foreseeable future. Big Al’s boardwalk view across the former Rivers of America and a walkway behind shops could vanish from public sight as work expands. Meanwhile, Big Thunder Mountain Railroad prepares to reopen on May 3, 2026, following a year-long refurbishment with refreshed effects and smoother operation. Disney has not confirmed an exact timeline for the latest changes.
