That hole is deep. I was checking it out the other day, and was surprised by how deep it is.

That's the first station up the hill, will it be lower than the others to reduce the climb from GNW?

City Hall will be the lowest. I think Mount Pleasant is about the average.

City Hall



Arbutus

Weird they haven't announced anything with the TBM.

Edit: Back in August

It looks like assembly is still in progress. Recently the conveyor structure up to ground level near 1st Ave has been built.

Could be that the bored tunnel needs a certain thickness of soil above to maintain support for the surface above.

I was in Vancouver last weekend and walked along the Broadway corridor to check out the SkyTrain subway construction. It was a bit of a mess in some areas with narrow sidewalks in construction zones, but some headaches now will be worth it in the future when the extension opens! I've lived in DC, Chicago, and now in the SF Bay Area and I have to say riding SkyTrain was a much more pleasant experience than any of the rapid transit systems in those three areas. Anyway, here are some photos I took during my walk from west to east along Broadway.

Arbutus construction area:










South Granville construction area:




Oak-VGH construction area:










Broadway-City Hall construction area:










Mount Pleasant construction area:










(I didn't make my way up to Great Northern Way-Emily Carr.)

I think it's extra deep because the tunnel has to go underneath the big sewer pipe that you can see near the top of the photo where the TBD is being assembled.

True, and probably other connections under Broadway itself.

arent they also going under buildings in this first section while turning under broadway? i imagine that must have some implications for both the buildings, and possible future buildings.

Some of them are already suing the project.

The claim concerns the government requiring land under The Brunswick apartment building at 396 East 2nd Avenue for tunnelling purposes. An advanced payment of $461,000 was paid to the owners Sept. 17, 2020.

“As of the filing of the notice of civil claim, the project had not yet commenced on the subject property, and the full physical and financial impacts of the project and the loss of the expropriated rights were not yet fully known,” the claim said.

“It is anticipated that the subject property and the apartment building will suffer physical damage as a consequence of the project, and it is anticipated that the owner will suffer considerable financial losses, costs and damages.”

The Brunswick is a 53-unit, four-storey apartment building built in the late 1970s. It is located just south of Great Northern Way, behind St. Francis Xavier school. The property is a short walk from what will be the Great Northern Way-Emily Carr station.

A government map of the subway route shows the tunnel will descend from Main and Broadway and run under Brunswick Street, which is located on the west side of the apartment building.

In an interview last week, Cooke said he understood there were no immediate plans to redevelop The Brunswick, but noted any future redevelopment could affect construction of a deep underground parkade.

There could also be restrictions about what the owners could develop on the surface of the property, knowing a subway was running underneath the land, he said.

“There might be rules like, ‘You may never build over this tunnel,’ or ‘You may not put a parking lot over this tunnel,” — or sometimes, more vaguely, ‘You may not do anything over our tunnel without getting our prior written consent, which we may never give you if we don’t think it’s reasonable,’” Cooke said.

He said he filed a claim July 15 to meet the one-year limitation set out in the Expropriation Act. So basically, Cooke added, “it’s just like a foot in the door to make sure that the owners’ rights are protected.”

The tunnel doesn't have to stay at the same elevation for its whole length even if it has to dive deep to go under buildings.
The Canada Line Vancouver City Centre station (and others downtown?) is built on a rise so trains slow with gravity entering and accelerate with gravity exiting the station.

Thanks!
I just clued in that they're doing 2 simultaneous bores, rather than re-using the same TBM, as they did for Canada Line.
