It is parallel with Interstate 5. It begins at Interstate 5 near Wheeler Ridge, and continues north through the major cities of Bakersfield, Fresno, Chowchilla, Modesto, Stockon, Sacramento, Chico, and Red Bluff. Most of it is freeway, but some of it is still the historic rural two-lane road or a four-lane highway.
