Ok, maybe this is me being nerdy but I found this seriously cool! We're on day 33 of our Xinjiang RV roadtrip and today we're going through one of China's most impressive recent engineering accomplishments: the longest highway tunnel in the world, almost 23km long, going underneath the TianShan mountains (called the "Tianshan Shengli Tunnel"). It opened in December last year. What's truly cool is that we managed to visit the tunnel command center, from which they monitor the traffic in the tunnel in real time. It's a FAR more sophisticated operation that I expected: look at this 👇, they monitor each individual car and truck in real time on a massive screen, and have advanced AI systems surface any issue the very second it arises. Without a doubt the single most high-tech tunnel monitoring system in the world. This tunnel is actually genuinely transformational for Xinjiang, probably the single most transformational infrastructure project in the region this millennia (so far): the big issue here is that you have the TianShan mountains, some of the highest mountains in the world (over 7000m high) that literally divide the region in 2 between North and South Xinjiang. Before the tunnel the only way people could travel between North and South (or vice versa) was through small perilous roads through the mountains, or by driving around the mountains - in either case a massive (and often dangerous) journey that would take many hours. The tunnel cuts it down to... just 20 minutes! The highway and tunnel cost an absolute fortune to build - some 40 billion yuan - and there's no way they're ever going to get it back from toll fees alone. But we asked the staff here and they said that when you consider the impact it'll have on Xinjiang's economy as a whole, it's not even close. And that's kind of the whole Chinese infrastructure philosophy in a nutshell: infrastructure is seen as a catalyst, you measure the return across the entire region for the next 50 years.
