Looking at the Harbor Freeway construction photos and all made me think of another research source that NLAers might like - the California Highways & Public Works magazine. It was put out by the California Division of Highways (now Caltrans) 1924 to 1967 as a promotional journal to document roadbuilding progress but now is a source for articles and photos of historical interest. It covers the whole state but LA area got a lot of coverage, especially with the freeways.
There's an index to the years 1937 to 1967 in PDF , searchable by keyword here
And a seperate index for the photographs that go with the articles here
Even without the magazines, the index is handy for showing about when certain bridges or freeways segments were started or dedicated. But all the issues have been put online in PDF format.
has them organized so you can flip through them and save pages as images. They aren't Shulman-quality, but most have been little seen if at all. They're from the collection of the Dept. of Transporation and haven't been digitized.

This bungalow at 1422 Bellevue went to 2486 Silverlake Blvd. The hideous modernization was “quite expensive.”
429 N. Belmont St got moved to 226 N. Westlake and some alterations for a “much more pleasing look.”
5107 Edmund St. went to the NW corner of 4th St. and Serrano. “It has been changed to as to be hardly recognizable.”
