SR-120 at Calla Road Live Traffic Cam, Cornerstone
About this camera
This roadside camera keeps an eye on Highway 120 at Calla Road in Cornerstone, California, facing the eastbound lanes, giving a real-time picture of how traffic is moving.
State Route 120 runs from I-5 near Lathrop through Manteca, Oakdale and Groveland to Yosemite National Park, crossing Tioga Pass to Lee Vining. Between I-5 and SR-99, SR-120 is a busy freeway bypass of Manteca, while to the east it becomes a scenic route toward Yosemite's Big Oak Flat entrance. Cornerstone is a rural area in San Joaquin County.
Tioga Pass closes in winter, and snow can affect higher elevations. Commuters and trucks use the Manteca bypass, while summer weekends bring Yosemite traffic. Weekend and holiday travel can turn a quiet country road busy, and the camera shows how things look right now.
Images may look grainy at night or during heavy rain, but the flow of lights still tells the story. The live stream is provided by Caltrans, the California Department of Transportation.
