The California Highway Patrol says the collision happened near Belmont Avenue and North Del Norte Avenue just after 10 pm.
The woman, 40-year-old Rosemary Montiel, was driving east on Belmont Avenue when she lost control of her car and veered off the roadway.
The car's front bumper crashed into a vineyard and kept going until the driver's side front door hit a large concrete agricultural standpipe.
Montiel died at the scene.
CHP officers are investigating what led to the crash, but say they do not believe alcohol and drugs were a factor.
