Official Engineering Plans for the Construction of Highway 150 from Carpenteria to Ojai.

[Sacramento]: Department of Pubic Works, 1934. First edition, Oblong folio (13 1/2 x 10 1/2 inches). 13 leaves, blue line maps and others printed on rectos only. Original brad-bound clue cloth with a window near the same to dispay the engineers name. Old small stain in upper corner, ese very good.This set of blueprints was only for 3 miles of the highway, from East Carpinteria along Rancho El Ricon along Casitas Creek to just past the West Casitas Pass. It includes detailed delineation of the planned highway, a public works project during the Great Depression, with elevations, etc., and designs for culverts, guard rails, supports, drains, etc. Formerly belonged to W. J. Calvin, with pencil note in the margin of the first leaf “ Please return W. J. Calvin, Resident Engineer. P.O. Box 'P' Carpinteria, Calif." Calvin worked in the area for more than thirty years. There are occasional pencil notes, diagrams, etc. on the plans, apparently by Calvin.The western terminus of Highway 150 is at US 101 in eastern Carpinteria. It climbs above the Pacific Ocean to reach the mountains west of Lake Casitas. The portion of the road between US 101 and Lake Casitas is called Casitas Pass Road, and the portion between Lake Casitas and Ojai is called Baldwin Road. However, this part of the road is rural and is not used as a primary thoroughfare. SR 33 is recommended to reach Ojai from U.S. 101. SR 150 joins SR 33 (Maricopa Highway) near Meiners Oaks and remains co-signed with the route into the Ojai city limits, where it is known as Ojai Avenue. It runs southeast on Ojai-Santa Paula Road and serves as the major connector between the cities of Ojai and Santa Paula, running past Thomas Aquinas College. In Santa Paula, it becomes 10th Street and ends at an interchange with SR 126.
