SR-99 at Fulkerth Rd Live Traffic Cam, Turlock

In Turlock, Stanislaus County, this camera keeps watch over SR-99 at Fulkerth Road, showing southbound traffic. Fulkerth Road serves Turlock's northern business district, and the city is also home to the Stanislaus County Fair every July.

Through Modesto, Ceres and Turlock, SR-99 is a true city freeway, lined with shopping centers, packing houses and new subdivisions. Modesto is the county seat, and from here SR-132 and SR-108 head east into the foothills toward Yosemite and the Sonora Pass country.

Before it became a state route, this road was US-99, the old Golden State Highway, sometimes called the Main Street of California. The modern freeway follows much of that historic alignment, which is why so many valley towns grew up right beside it.

Weekday rush hours bring the heaviest local traffic, but long-distance trucks keep the right lanes busy at all hours. Holiday weekends add a wave of travelers heading toward Yosemite and the Sierra, and winter tule fog is the hazard drivers worry about most. Many drivers check it before the morning commute or a weekend trip to decide when to leave.
