I-70 mountain traffic went big this Presidents’ Day holiday for the busiest four consecutive days of ski season.
More than 41,000 cars passed through the Eisenhower-Johnson tunnels daily, Feb. 13 to 16, peaking with more than 45,000 cars on Presidents’ Day Monday.
It was the busiest four-day holiday on I-70 since Labor Day, busier than MLK Weekend this year and even Memorial Day last year.
Compared to recent Presidents’ Weekends, this year was 29 percent busier than last year, when a snowstorm jammed up the corridor. It was slower than the previous two years in 2024 and 2023.
Presidents’ Day tunnel counts (vehicles in 4 days)
- 2026… 172,676
- 2025… 133,948
- 2024… 180,804
- 2023… 186,694
- 2022… 195,466
- 2021… ~153,000 (pandemic ski reservation season)
- 2020… ~183,000 (pre-pandemic shutdown)
So far this ski season only four-day holidays have outpaced last season on the mountain corridor. The biggest reason is weather. A brief overnight storm this past Friday, Feb. 13 jammed up a few hours of holiday traffic, but 41,000 cars still made it through the tunnels.
Last year, no more than 40,000 cars traveled the tunnels in 24 hours of Presidents’ Weekend. The very next weekend nearly 49,000 cars traveled through Summit in one day.
