U.S. Route 399 - Route Description

Route Description

From its original junction at U.S. Route 101 in Ventura, California, the route continues along State Route 33 up to Ojai, temporarily joining State Route 150. Leaving Ojai, it continued into the Los Padres National Forest along the Maricopa Highway, with its summit at Pine Mountain. Descending into the Cuyama River Valley, it met State Route 166 and travelled east towards Maricopa past what is now the Carrizo Plain National Monument and crossing the axis of the San Andreas Fault into the southern San Joaquin Valley. In Maricopa, it continued north again with State Route 33 into the southern Midway-Sunset Oil Field and intersecting modern State Route 119 in Taft. From Taft, U.S. 399 followed State Route 119 out of town through Valley Acres and past the modern Buena Vista Recreation Area (the old Buena Vista Lake) towards U.S. Route 99 (now State Route 99) in Pumpkin Center and Greenfield, then with the old alignment of U.S. Route 99 (Union Avenue, SR 99 Bus.) north into Bakersfield where it terminated. This ending, being a useless concurrency, was later truncated to U.S. Route 99 until U.S. Route 399 was decommissioned.

The route was subsequently realigned several times, most notably the original Ojai Freeway in southern Ventura which is now the modern State Route 33 freeway, and the expressway bypass of eastern Taft which is now the modern State Route 119 expressway.
