The Main Route: I-70 to Aspen

The primary route to Aspen from Denver involves taking I-70 West to Glenwood Springs, then south on CO-82. While this is typically the fastest and most direct route, it can be affected by closures at two key points:

Potential Closure Points

1. Eisenhower Tunnel: At an elevation of 11,158 feet, this tunnel is one of the highest in the world and frequently faces challenges from snow and ice, leading to periodic closures.
2. Vail Pass: At an elevation of 10,662 feet, this stretch is similarly susceptible to winter weather conditions, which can cause traffic backups and occasional closures.

These areas can experience significant delays, accidents, and even avalanche risks, making planning and preparing for potential detours essential.
