I-80: Sacramento to San Francisco Traffic Cameras
I-80 is California's main east-west lifeline, connecting Sacramento to the Bay Area and beyond. Over 180 miles, this freeway carries daily commuter traffic and regional travelers — especially the high-volume section across the Sierra Nevada in winter.
Check live cameras before driving this corridor. Conditions change rapidly, especially in mountain passes and at the Bay Bridge approaches.
Sections to Monitor
Sierra Nevada (I-80 over Donner Pass): During winter, this is critical. Snow, ice, and chain requirements are visible on cameras. Check cameras before any December-through-February trip.
Bay Bridge approaches: I-80 westbound into San Francisco is heavily congested 7–10 AM. The bridge itself narrows to 5 lanes, creating a bottleneck.
