From the Archives: A Blast from the Past on PCH (SR-1)

The pictures above were taken between 1923 and 1925 for the construction of the Pacific Coast Highway (SR-1) in Los Angeles County.  As you can see, some of the path of the SR-1 had to be blasted. 

In picture 414-05 (March 20, 1924), according to the engineer's journal, 24,675 pounds of black powder were used for the blast.
