Nice! I can finally locate LA's Scattergood-Olympic underground transmission line that was repaired in 1989 to much engineering prowess [1].

I love infrastructure engineering. There's so much going on that allows us to take things for granted. Even the 2021 Texas power grid failure fared relatively well for how close it skirted absolute disaster.

(I should give Grady more money) People here may remember jwz's post on the topic in 2002, copying the emails from 1989 (note the following link may display something unsavory with the HN referrer, in which case copy-and-paste it): https://www.jwz.org/blog/2002/11/engineering-pornography/

A new line was put in in 2018 for $130mm. "The new transmission line is an addition to the original line which began commercial service in 1974 and had been experiencing reliability issues. The original line will be used a backup, should it be needed."
