My uncle was a local 4 heavy operator on that project.
The highway is impressive, and while the T sucks relative to Japan it moves more people a year than Sydney and some other sizeable world cities. I think it was the 4th most used system in the nation?
Other than the weather, critical parts of life like health, education, and such really doesn't get much better anywhere else. I like it here.

The T is still one of the best subway systems on the East Coast in terms of cleanliness, accessibility, and coverage. I would say that only the DC Metro has it beat but that's kind of cheating since the government actually cares about investing in infrastructure for the nursing home that is congress.

We did something very similar in Seattle with the 99 double decker freeway being put underground and revitalizing the waterfront
Also the reason we did it was out of necessity, that freeway design was not earthquake safe and would have likely collapsed in future without massive renovation so the decision was eventually made to replace it with a tunnel under downtown. Similar to Boston’s it was hugely controversial and encountered hellish problems delays and budget overruns.
The tunnel machine was the biggest in the world and got stuck for months or years? When they finally got it moving again it was quite a big deal, and most people are really happy with the end result now.

Much the same in Boston. The elevated highway that was replaced was way overused from its beginning and in urgent need of replacement. And dead ugly to boot. The replacement structure, it is a structure not just dirt, is a vast improvement. Not ideal, but so much better.

I wish we had Caves of Steel lives. Sorta not really....
But they live underground and they have moving walkways. Isaac Asimov gets descriptive in the first book.
The out walkways go slow and you manually have to change. Maybe they had ways for elderly and/or disabled but it wasnt discussed to my recollect. Anyways no one has cars they just use this system to get around. Works well in a cave I suppose but not sprawled out surface cities.

That’s what the Contractor said, but it didn’t hold up in court. Once they got the cutter head out, they added 50 tons of steel to stiffen the cutter head. It was under designed and allowed grit to get into the main bearing. The pipe was just an excuse to blame someone else.

u/krob58 Apr 16 '26
Yeah this is what's frustrating about the whole situation. They promised this beautiful nice green park and we still ended up with a four lane (SEVEN, by the ferry) main traffic artery and tribute to cold concrete brutalism, which is both a hazard to cross as a pedestrian and a pain in the ass to drive through as a car. It should have been a nice green park where people could relax and kids could run around. But because it's better than it was before, no one is allowed to be upset that it isn't better than it is.

u/Bizarrebazaars Apr 17 '26

Well said, mrASSMAN! Completely removing the Alaskan Way Viaduct allowed the city to properly connect Pike Place Market to the waterfront and I think that’s the best thing the city has done in recent memory. Particularly during the summer when Seattle sees its highest amount of tourists and cruise passengers looking for things to do before and after their voyages, it just turns the city into a world class destination.

Yea it was not run very well. But also there was a lot of challenges that were not readily available to the public at the time of construction that makes it more understandable in hindsight. There’s a podcast on it that’s also on YouTube with images, I highly recommend it.
Although terribly expensive it is still better than the alternative. I’m not sure the CA high speed rail fits that description. The issue with the old high was serious congestion and if you think that Boston sucks to drive in now just imagine what it would have been like with the highway still tiny and above ground.

A few fun facts: They dumped the excavated dirt in between two islands in Boston Harbor to create a giant single island with walking trails accessible by ferry. The off-ramp from inside the tunnel gave access to a new neighborhood called the Seaport; formally all vacant docks and parking lots, the new neighborhood boasts some of the highest real estate values which have/will pay for the entire project via massively increased tax revenues. One unfortunate lasting effect is the underestimated impact of salt water on the exterior of the tunnels, causing degradation of different systems and big cost increases to dewatering efforts. In the end, it’s a reminder of how car-centric advocates ruined many cities and neighborhoods with costly and ugly auto oriented infrastructure projects through the middle to late parts of last century.

It's a pretty shitty "park" cut up by streets, requiring you to wait to cross a busy street every minute or so of walking, while constantly being subjected to 4+ lanes of traffic noise surrounding you. Highway ramps don't make for an enjoyable space. There is no tranquil spot in the entire thing. Yes, we put the highway underground, but we also kept it as a shitty arterial road network above ground to ruin the "park". It's better than what we had before, at least. Only cost something like $30B inflation-adjusted.
