On April 14, 2026, a massive multi-vehicle accident involving over 75 cars occurred on Interstate 70 near the Eisenhower-Johnson Memorial Tunnel in Colorado. The primary cause was hazardous winter weather, specifically snow-covered roads, as reported by the Colorado Department of Transportation (CODOT).

Emergency services promptly responded to assist those involved, and the Colorado State Patrol is leading the investigation.
