The other day an Australian official Jeremy Buckingham via Twitter turned to Elon musk with a question: how much will it cost to build a 50-kilometer tunnel transport system through the Blue mountains? It is supposed to relieve the traffic in Sydney because the city, in the words of Buckingham, “gasping”. Elon Musk quickly had calculated and the amount was quite exciting.
One kilometer of the tunnel for movement in the two sides of the businessman was estimated at $15 million — apparently, this is the work of “turnkey”. The path length of fifty kilometers, respectively, will cost $750 million. Another $50 million cost of building a passenger station. Looks like the numbers are arranged Buckingham: the politician stated that he would discuss with colleagues the project and will contact Mask.
Without comparison it is difficult to understand a lot or a little — $15 million per mile of tunnel to traffic. But recently, a vivid example: the kilometer of the Minsk metro pull from the budget of 237 million rubles, or about $110 million. Of course, the technology and scope of work differ, however, the project Mask out seven times cheaper. And traffic speed in the tunnel, according to the promises of The Boring Company, will be disproportionately higher than normal metro — about 250 km/h.
