![]() This often happens on Interstate 80 over Donner Summit. Caltrans will close a highway to keep drivers off the road and prevent crashes. Sometimes a winter storm can be so strong that driving just isn’t safe. These road closures can last from a few hours up to a couple of days. Caltrans will close the road, intentionally cause an avalanche, then use heavy equipment to clear the snow slide from the road. Some of the passes are vulnerable to avalanches. Temporary road closuresĮven the highways that aren’t closed all winter can be closed temporarily during and right after a big storm. When winter hits the highest most remote Sierra Nevada passes Caltrans just locks the gates across the roads and makes plans to come back in the spring with heavy equipment to reopen the highways for travelers. Still, it just isn’t feasible to keep all the passes open all the time. The California Department of Transportation-Caltrans-works hard to keep most of the roads passable as much as possible. Wind gusts over the highest ridges often exceed 100 miles (160 kilometers) per hour.Ĭheck our Weather page to learn a lot more about the climate and seasons in the Sierra. It is fairly common for a single storm to drop three feet (one meter) of snow overnight. Winter snowfall in the Sierra is measured in tens of feet. Spring on Monitor Pass How dramatic weather affects Sierra Nevada passes Ten of those roads will take you from one side of the Sierra to the other. North of Tioga Pass, in less than 200 miles (320 kilometers) you’ll find another 16 paved pass roads. South of Tioga Pass, in Yosemite National Park, you would need to travel 180 miles (290 kilometers) down the Eastern Sierra before finding another paved road that crosses the mountains. With such rugged and challenging terrain, the Southern Sierra Nevada has a lot fewer paved mountain pass roads than the central or northern parts of the range. Eight other Southern Sierra Nevada peaks-Mount Humphreys, Mount Keith, Mount Darwin, Mount Kaweah, Mount Morgan, Mount Gabb, Mount Tom, Mount Pinchot-are more than 13,000 feet (3,962 meters) high. Nearby Mount Williamson and North Palisade are both more than 14,000 feet (4,267 meters) high. The mountains are taller, steeper, more dramatic, and more remote toward the southern end of the range than in the north. Yet less than 100 miles (160 kilometers) away lies the lowest elevation (282 feet, 86 meters, below sea level) in North America at Badwater Basin, in Death Valley National Park. ![]() Its summit is 14,505 feet (4,421 meters) above sea level. The highest peak in the Sierra Nevada, in California, and in the contiguous United States is Mount Whitney. The mountains are about 40 to 80 miles (60 to 130 kilometers) wide and separate California’s fertile Central Valley from the high desert of the Great Basin, in Nevada. The Sierra range runs north and south for about 400 miles (640 kilometers) between Tehachapi Pass, in southern California, and Fredonyer Pass, in far northern California. Watch for deer and elk, and coyotes in the roadway.The view from Minaret Summit on CA 203 The Sierra Nevada range is big and rugged Please drive with caution and at speeds appropriate to the road conditions. The distance from Grand Canyon Village to Desert View and the East Entrance to the park is 23 miles (37 km).Watch for icy areas on all roads in and around the village.ĭesert View Drive is usually open to all vehicles, however, the road often closes during, or just after snowstorms. South Entrance Road is open to Grand Canyon Village.At that time the information below will be updated. The following road status information is valid from Wednesday, Maat 1:30 pm, and it will remain valid until conditions change. During the winter, road conditions can change rapidly.
