The Tejon Pass /teɪˈhoʊn, təˈhoʊn, ˈteɪ.hoʊn/, previously known as Portezuelo de Cortes, Portezuela de Castac, and Fort Tejon Pass is a mountain pass between the southwest end of the Tehachapi Mountains and northeastern San Emigdio Mountains, linking Southern California north to the Central Valley. Both the pass and the grade north of it to the Central Valley are commonly referred to as "the Grapevine". It has been traversed by major roads such as the El Camino Viejo, the Stockton – Los Angeles Road, the Ridge Route, U.S. Route 99, and now Interstate 5.
