That’s your “disaster?” 6 miles of new train line (4.5 underground) for $3.5 billion. Total construction time 15 years.
The first phase of the Second Avenue subway cost $4.5 billion for just 2 miles, and took 10 years. The next 1.5 mile segment will cost $6 billion (that’s just the estimate) and take another 10 years. And that’s not even all that over budget or delayed.
I’ve never encountered a major public project in the US that was on budget and on time. I’m sure there are some, but that’s not the rule. Here in the DC area, we recently spent $150 million on a bus station (it’s a nice, 3 level bus station on existing public land). That was delayed and was $50 million over budget. The $6 million renovation project in the parking garage at the metro station nearest to me is years behind schedule. The purple line in Maryland is years late and billions over budget. The silver line in Virginia is years late and billions over budget.
Your “disaster” would be a miracle in a major US city. Such a miracle that few cities are even contemplating such things. DC, for example, is growing rapidly, and WMATA desperately needs another tunnel through downtown. And people are willing to spend that kind of money—WMATA just invested $6 billion and a decade constructing the silver line to Virginia. And Maryland is investing a similar amount in a light rail through the suburbs. But a downtown tunnel would be a $15+ billion, 20-year project here.
To us, that was a disaster yes. I suppose we measure or weigh things differently? Or perhaps we haven't had those monstrosities you mention so we have no local reference.
Just as a minor counterpoint, the Anacostia River Tunnel project was finished on time, and the overall clean rivers project is on time and under budget by nearly 100MM so far.
Granted, it doesn't face WMATA's absolutely insane leadership and funding structure, but it can be done, and even in one of the most complex jurisdictional messes in the US.
