Closing weekend at Copper sees a few thousand more cars on I-70 

Weekend traffic on I-70 ramped up again with a dash of fresh snow and a healthy dose of closing weekend energy. 

Just under 93,000 vehicles traveled the Eisenhower-Johnson tunnels this past Friday into Sunday, May 1-3. It was a second-straight weekend of rising traffic, but a third-consecutive weekend of traffic slower than 100,000 cars. This continues the longest streak of sub-100k traffic in nearly six years. 

This is the first weekend I-70 is settling back into a “typical” spring pattern. Traffic was just barely slower than the same time last year. For most of April the mountain corridor was slower by 12,000 to 20,000 vehicles every weekend. In four weekends, this April ended up with 50,000 fewer vehicles than April 2024.  

For skiers and riders out lapping Copper Mountain on closing weekend, the drive was worth it. Copper claimed more than a foot of snow this past week, capping off a surprisingly snowy April with a (near) powder day on Friday, May 1, when there was twilight skiing and a D.J. set at the Aerie mid-mountain lodge.
