Real-Time Sierra Nevada Road Conditions
At i80pass.com, our mission is simple: to provide the most reliable, real-time road condition updates for travelers crossing the Sierra Nevada. We bridge the gap between official Caltrans data and the need for quick, actionable information, helping you make safer travel decisions before you head into the mountains.
Mountain travel—particularly over the I-80 Donner Pass and US-50 Echo Summit—demands respect and preparation. We recognized that travelers heading from the Bay Area and Sacramento to the Lake Tahoe region and Reno often face sudden weather shifts, chain control requirements, and unexpected traffic delays. Our platform was born out of the need to strip away the “noise” and provide a streamlined, instant status of these critical mountain corridors.
We aggregate official data to deliver the information that matters most to drivers:
Real-Time Status
Immediate updates on whether passes are open or closed.
Chain Control Alerts
Instant notifications on R1, R2, and R3 chain requirements so you are prepared before reaching the checkpoint.
Webcam Feeds
Visual verification of conditions at key elevations, including Donner Summit and Echo Summit.
Traffic Monitoring
Alerts for high winds, brake check requirements, and traffic delays to help you plan your departure time.
While our namesake focuses on the I-80 corridor—the primary artery between Northern California and the high Sierra—our commitment to safety extends throughout the region. We provide critical data for travelers navigating:
I-80 Donner Pass
The most heavily trafficked route between the Bay Area and Truckee/North Lake Tahoe.
US-50 Echo Summit
A vital route for those traveling from Sacramento to South Lake Tahoe.
Supporting Routes
Updates for SR-89, SR-28, and other essential connectors throughout the Tahoe Basin and Sierra Nevada.
We believe that preparation is the key to a smooth drive. Whether you are heading to the slopes for a ski trip, commuting, or exploring the Tahoe region, our goal is to ensure you aren’t caught off guard by a storm or a surprise closure.
