Take some time to research safety and deaths in large construction projects happening today at the scale of bridging the Golden Gate back in the 1930s. E.g. Channel tunnel - 10 deaths, Panama Canal Expansion - 7, Three Gorges Dam - 100+, Gotthard Base Tunnel - 8, Hong Kong–Zhuhai–Macau Bridge - 19, Istanbul Airport - 55. I'm not sure what statistics you are looking for, but construction isn't a no-risk profession even in modern times. If you want to just look at America - 3 people died at the Hard Rock Hotel construction site in New Orleans last year. Two people have died in the last two months building the SoFi Stadium in Los Angeles. Two more died digging a trench in Phoenix two weeks ago.
You're getting downvoted because more than half of your examples are from non-Western countries with appalling safety regulations.
We already know authoritarian dictatorships (China, Turkey) can still achieve amazing infrastructure projects, damn the cost to human life or displaced poor people.
Fromt eh Western examples, Gotthard Base Tunnel work began in 1999 and it opened almost 17 years later, so that's less than 0.5 deaths/year. The Channel tunnel is then probably the only remaining example.
The other examples prove the point - safety standards have gone up and very few people die during major construction projects
