Denali road cut back

Denali National Park’s main road will stop at Mile 43 this summer after new rock slides damaged the only route deeper into the park. (nps.gov) The National Park Service said the closure at Mile 43 will stay in place through the summer 2026 season, which runs from mid-May to mid-September. Transit and tour buses will go no farther than the East Fork Bridge at Mile 43. (nps.gov) That leaves the western half of the 92-mile park road off limits to road traffic for another season. Eielson Visitor Center and Wonder Lake Campground will remain closed in 2026. (nps.gov; nps.gov) The bottleneck is the Pretty Rocks landslide near Mile 45.4, where the road crosses a slope that has been moving for decades and sped up sharply in 2021. The National Park Service said movement rose from inches per year before 2014 to as much as 0.65 inches per hour in 2021. (nps.gov) Park managers closed the road west of Pretty Rocks in late August 2021 after repeated gravel repairs stopped being safe. Since then, buses have been unable to reach stops including Polychrome Overlook, Toklat, Eielson and Wonder Lake. (nps.gov; nps.gov) The long-term fix is a bridge over the slide zone plus road work near another unstable area called Bear Cave Landslide. The Federal Highway Administration and the park say bridge work stayed on schedule in 2025, with the span launched into place and deck panels installed. (nps.gov; nps.gov) The agencies still expect a midsummer 2026 construction finish, but they plan to spend the rest of that season repairing the western road and deferred facilities before reopening the full route. Full road access and full bus service are expected in 2027. (nps.gov; nps.gov) Visitors can still use the entrance area and the drivable eastern section of the road. The Denali Visitor Center sits near Mile 1.5, the sled dog kennels are around Mile 3, and free shuttles serve stops up to Mile 15 in summer. (nps.gov; nps.gov; nps.gov) For travelers who book Denali to ride deep into the park, 2026 will look a lot like the last four summers. The difference is that the bridge now spans the slide, and the park is counting down to a 2027 reopening instead of an open-ended closure. (nps.gov; nps.gov)
