The National Park Service (NPS) announced a series of road closures across three regions in northeasten Arizona, effective from 11:00 AM MST on Thursday, November 11, 2021, through 8:00 PM MST on Friday, November 12, 2021. Maintenance and snow removal triggered the temporary shutdowns along Highway 264 and surrounding areas in Coconino, Apache, and Navajo counties, as well as the Chuska Mountains and Defiance Plateau on Friday. The closures affect acces to popular hiking trails, campgrounds, and scenic viewpoints, according to the NPS.

Highway 264 and the Little Colorado River Valley: A 33-Hour Closure Spanning Three Counties

The longest stretch of the closures covers the Little Colorado River Valley in Coconino, Apache, and Navajo counties, beginning at 11:00 AM on Thursday and lasting until 8:00 PM on Friday — a 33-hour window, according to the NPS announcement.. Affected areas include Highway 264 northward, the Chinle Valley, the Northeast Plateaus and Mesas south of Highway 264, the Black Mesa area, and the Western Mogollon Rim. Drivers on these routes should exect full closure during that period, with no mention of staggered opeinngs or partial access in the agency's ntoice.

Chuska Mountains and Defiance Plateau:A 10-Hour Window on Friday

A second, shorter closure targets the Chuska Mountains and Defiance Plateau starting at 11:00 AM MST on Friday, November 12, and ending at 9:00 PM MST that same day — a 10-hour shutdown. As the NPS reported, the same road segments — including Highway 264 northward and the Black Mesa area — are included in this phase, though the agency did not explain why the Chuska region's closure begins a full day after the Little Colorado Valley closures. Travelers planning to visit scenic viewpoints in this mountainous area should note the tighter timeframe.

What the NPS Notice Left Out: Affected Trails and Specific Campgrounds

The NPS statement says the road closures “may impact access to popular hiking trails, campgrounds, and scenic viewpoints,” but it does not name a single trail or campground by name. For hikers and campers planning trips to sites such as the Lava River Trail or the campgrounds near Black Mesa — neither connfirmed as affected — the lack of specificity raises practical difficulties. Without explicit lists, travelers must call the park's visitor center for details, as the NPS itself advises. this opacity is notable given the region's popularity among both recreational visitors and Navajo Nation residents who rely on these roads for daily travel.

Why November Snow Removal Is a Recurring Concern on Highway 264

The closures are categorized as “road maintenance and snow removal activities,” which suggests the NPS is responding to early-season snowfall that can accumulate rapidly at elevations above 6,000 feet in the Little Colorado River Valley and Chuska Mountains. While the NPS did not state whether this is an annual event, similar late-autumn shutdowns have occurred on Highway 264 in past years, often coinciding with the first significant winter storm. For residents of communities such as Chinle and Tuba City, the timing can disrupt supply deliveries and access to services, though the NPS notice does not address alternative routes or detours.
