The original Conejo Grade was completed by the California Highway Commission in 1915 as part of the Coast Highway. The climb contained 49 curves. In 1926 the Conejo Grade/Coast Highway was desiginated US 101. In 1937 a new alignment of the grade was completed, reducing the curves by 75%. The width of the roadway was now three lanes, with a passing lane down the middle for traffic going in either direction. The present freeway, essentially a widening of the 1937 alignment, was completed by 1959 and intially consisted of six lanes. Men and machinery can be seen on this mountain road, possibly the Conejo Grade, as cactus has naturalized near Camarillo Springs. A round sign can be seen at the very top of the hill, but it is illegible. Three machines are idle to the left of the photo, and approximately 17 men pose either on top of, or next to, another machine that lies on its side - possibly overturned while descending the grade.
