Is Siskiyou Summit closed?

Remember this is a mountainous area. Altitude and extreme weather are always a factor. Its proximity to the Pacific Ocean combined with its high elevation and hazardous curves, brings with its brutal amounts of snowfall and freezing rain, which are known to force Oregon D.O.T. officials to shut down the entire highway on occasion during winter. Always check the weather forecast before you start your journey. Snow generally falls during the months of November through April. The road is typically closed to traffic for many days during winter due to severe weather conditions. At times, it can be closed during winter even when the weather is fine. During winter, reaching the summit can be a challenge due to snow and ice on the pavement. Avoid travel during night and early morning hours in winter months. It is also recommended that drivers listen to updated weather information and road conditions on the radio before and during the entire journey through the pass.
