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
