Pretty sure the interstate highway system isn’t terribly practical either, but with enough funding it can be done. Maybe saying every major city would make it seem more practical.
Comment on What technological mega project is practical to build today?
Buelldozer@lemmy.today 1 year agoCoast to Coast? Sure, but every city in North America? Nah, that isn’t practical at all.
For instance France apparently builds high speed rail for 25 Million per kilometer so lets use their cost number. The straightline distance, shortest possible, from Denver to Omaha is 483 kilometers so the line from Omaha to Denver alone would cost 12 BILLION dollars.
Denver to Salt Lake is 590 Kilometers, again straight line, so there goes another 14.7 Billion dollars. SLC to Los Angeles is 930 kilometers, another 23.2 Billion.
We’ve now spent 49.9 Billion to connect just FOUR cities and only have a single rail line that goes from Omaha to LA.
Trying to connect every city in North America with High Speed rail not only isn’t practical it isn’t economically possible on any reasonable timeline a it would require a major percentage of the US’s entire GDP to be spent on it every single year for the next century.

France’s public infrastructure construction industry is one of the most corrupt and wasteful systems on earth 😂

In 2020 the US state and local governments spent $116 billion for the construction of roads and highways and $94 billion of operating costs.
If you just cancel half of the road construction projects by a year you get enough money to fund the connection of the 4 cities you described.
