Seasonal Driving Considerations
Mountain passes along this corridor can be treacherous from October through May, with chain requirements, road closures, and whiteout conditions at higher elevations. Summer brings its own challenges — afternoon thunderstorms are common above 7,000 feet, and construction season narrows lanes on key highways. Always check pass conditions before departing, and carry emergency supplies during the colder months.
