A compilation of the history of the street name changes in Los Angeles and those changed street segments are shown on a map. Currently 670 historic street names are listed, and 129 have been located and drawn so they can be seen altogether here or individually, for example, for Beaudry.
I started this to support Croatian Run Restaurants in Los Angeles 1880—1930 but then saw a general need and was able to leverage the extensive list published by Steve Morse: Los Angeles in the 1900s—Streets of a Hundred Years Ago. Morse's site is a treasure trove of historical and genealogical information. Almost all of the street changes are from Morse. I've added the ability to put that information on a map and have started map the entries. After launching the site, anyone will be able to add or edit the entries.
Have to add earliest Spanish names shown on some maps, e.g, Calle de las Primavera for Spring. Were those official? They’re on an 1857 Bancock and Thayer et.al. map.
Inspired by Chris Salvano's San Francisco Historical Street Names Index and MaptimeLA people, workshops and tutorials.
The historic maps can be slow to appear. The coverage of the maps varies and sometimes no map will be available for the area of interest.

For now I'm focusing the list on the City of Los Angeles, but should allow for other cities in the county. Here's a link to street name history for Redondo Beach at the Redondo Beach Historical Society
