Berthoud Pass takes US 40 over the Continental Divide at 11,307 feet, between Empire and Winter Park. It is the direct road from Denver to the Fraser Valley, a continuous climb of switchbacks with no tunnel beneath it, and traction restrictions on the grade are common from October into May.

No full closures are reported on Berthoud Pass as of Oct 8, 2026 8:51 PM MDT, and no lane closures or roadworks either. Always check with the responsible state DOT before setting off.
Chain and traction requirements on Berthoud Pass are set by the state highway authority, and they are imposed and lifted through the day as a storm moves through. This page does not carry them — check COtrip ↗ before you set off. What the levels mean, with the exemptions and what you have to be carrying, is on the Colorado page.
What this page can tell you is the surface at the summit, from radar and surface analysis: currently dry, with the road surface estimated at 36°F. The road surface figure is an estimate derived from air temperature, not a measurement — bridges and overpasses run colder than the number shown.
At the summit, 11,307 ft. Each day shows its warmest and coldest hour, and the worst driving conditions forecast anywhere in it — not the average, because the hour that closes a pass is the one worth knowing about.
