Route description

Route 128 begins at Route 1 near the mouth of the Navarro River at the Pacific Ocean. The highway travels southeast through Navarro River Redwoods State Park and through the Anderson Valley to Boonville. Route 253 terminates into Route 128 at the south end of Boonville. Leaving Boonville, Route 128 climbs out of the Navarro River watershed and crosses the Yorkville Highlands into the Russian River watershed, arriving at Cloverdale in the Alexander Valley, where it joins U.S. Route 101 heading south. A few miles later, at Geyserville, Route 128 separates from U.S. 101 and crosses Knights Valley on the way to Napa Valley, where it joins Route 29 at Calistoga. After passing through the town of St. Helena, Route 128 splits from Route 29 at Rutherford and climbs east over dry ridges above Lake Berryessa to the Sacramento Valley. In Winters, the route's constructed portion ends at Interstate 505. By its legal definition, the route continues 14 miles eastward to Route 113 at Davis and Interstate 80 but this segment is currently not constructed.
