SR-99 at Griffith Rd Live Traffic Cam, Turlock

Mounted beside SR-99 at the Griffith Road overcrossing, this camera gives a continuous view of southbound traffic in Turlock, Merced County.

Stanislaus County is centered on Modesto, the hometown of filmmaker George Lucas and the inspiration for American Graffiti. Downtown Modesto's famous arch reads Water, Wealth, Contentment, Health. South of the city, SR-99 passes Ceres and Turlock, home of California State University, Stanislaus, and to the north it runs through Salida toward the Stanislaus River.

SR-99 is one of California's hardest-working highways. It carries commuters between valley cities, families heading for the Sierra, and a steady procession of big rigs hauling produce, dairy, nuts and wine out of one of the most productive farming regions on Earth.

Traffic on SR-99 never really stops. Big rigs run day and night, and morning and evening commutes slow things around the larger cities. In winter, dense tule fog can settle over the valley floor and cut visibility sharply, while in summer the heat can be intense. Use it to see real conditions instead of guessing, whether you are commuting, hauling freight or starting a road trip.

Caltrans (the California Department of Transportation) provides this feed, one of hundreds of public cameras across the state.
