It seems unlikely as phase 2 is only planned to go to Arbutus. The presence of a gas station on the corner of W Broadway and MacDonald seems a more likely explanation.

isnt phase 1 going to arbutus and phase 2 to UBC? seems weird they'd be doing geological studies past arbutus unless they will be planning to UBC now and then just build it phased. would be cheaper i would imagine then having to do more studies later. not like ground conditions will change that fast, hopefully...

isn't phase 1 what already exists ending at vcc clarke?

Mac Write · #**8044** Posted **May 7, 2017, 8:59 PM**

Yes
Phase 1 - VCC > Columbia
Phase 2 - Laughed > Douglas
Phase 3 - VCC > UBC (orginal plan).

yes, from almost 20 years ago. this is pretty much an independent project now, being built in 2 phases being attached to the already complete Millennium-Line.

Right. TransLink's new 10-Year Plan has Phase One as bus improvements and Phase Two as the Arbutus extension/Surrey LRT/Patullo replacement. Digging to UBC is probably Phase Three... or part of TransLink's Great Leap Forward.

but that's for the whole plan. if we are talking about Broadway specifically wouldn't phase 1 be to Arbutus and then phase 2 to UBC? that makes sense to me, for this specific corridor anyways.

but i don't know. i don't follow these projects enough, I'm just hoping for 2 individual bored tunnels and that for construction they widen 12th Ave by a lane if it fits with the trees there.

This project is phase 1, 2, and 3 depending on which plans you are looking at

The Broadway extension to Arbutus is half of Phase 3 of the original Millennium Line plans (Phase 1: Columbia to VCC-Clark, Phase 2: Lougheed to Lafarge, Phase 3: VCC-Clark to UBC).

The Broadway extension to Arbutus is part of Phase 2 of the Mayors' Council 10-year transportation plan (Phase 1: bus service and design work, Phase 2: construction work).

The Broadway extension to Arbutus is Phase 1 of the Millennium Line Broadway Extension project (Phase 1: VCC-Clark to Arbutus, Phase 2: Arbutus to UBC).

Was SNC doing drilling on the rest of Broadway?

Thanks for listing the possibilities, Door 3 is indeed the one I was meaning.

Looking back at my previous posts, the stretch between Main St. and Manitoba St. was listed as "Private Contractors Environmental Investigation." The stretch between Hemlock St. and Granville St. was performed by Golder Associates Environmental Investigation

Metro-One · #**8051** Posted **May 8, 2017, 1:56 AM**

It is pretty clear in the context of the original question that phase one is VCC to Arbutus, and phase two is Arbutus to UBC.

Besides putting entrances on the four corners of Bway and Cambie, why not put one at the Ash or Yukon street end of the "box".
The box for the station will be almost the entire block between either Cambie and Ash or Cambie and Yukon.
Why make someone walk from Ash to Cambie and then walk back the length of the station underground. The same would go for a Cambie and Yukon box.
I have to wonder why that does not happen.

Yeah, they'll need to see if there's any contaminated soil that may have spread under either Broadway or MacDonald, because remediating that is a relatively costly and lengthy operation. They probably want to get that out of the way very early in the process.

Perhaps you could argue that the sink holes would be larger in a larger TBM because the area behind the cutter head is larger.

I'm not knowledgeable enough about tunneling to know if larger diameter handle boulders better. I do know that 1x10m diameter bore has a larger cross-sectional area than 2x6m diameter bores. This would mean it has a greater likelyhood of hitting boulders to begin with. From what I understand any encountering of boulders became a challenge on evergreen because of the mix of boulders & silty sands.

I have heard rumours that the ground will be better for tunneling along the broadway corridor.

Just zipped past the drilling going on near Broadway near Oak.

I noticed that one rig near Laurel was drilling vertically (90 degrees) as I've seen before, but the other rig closer to Oak was angled at 75 degrees drilling eastwards.

Any ideas as to why they are drilling at a non-typical odd angle?

I think Translink believes one entrance mezzanine is easier to keep secure than two or more.

However, most of the current Skytrain mezzanines also have an emergency exit at the end of the mezzanine opposite from the main station entrance. This is probably more to do with fire regs.

so ...

after the In-Decision 2017 earlier this week, who will be a better supporter (and funder) of the Arbutus extension?

Libs & Greens?
NDP & Greens?

I doubt the BC Libs are happy to pour money into NDP ridings - especially the ones they lost - so I won't be surprised to have funding for this project delayed until it can be announced by BCLibs with great fanfare just before (or during) the next BC election campaign. Which may be as soon as Fall 2018

On the other hand, if NDP gets power, they're more likely to shovel money into their ridings. And might even add another $ Billion to get the line built right out to UBC rather than stop at Arbutus. And during the next campaign the NDP can have lots of "see how good we're treating you?" ads.

i saw what i guess was drilling this past monday on broadway but i forget the cross street but it was about halfway between main and cambie.

If this election ends in a minority government, I see that as a bad thing for major projects. The appetite to make new multi-billion dollar investments will be light. Parties will be fighting for their lives and gearing up for the inevitable next election.

They may talk big, but commitments will be few and far between IMO.

Expected IMO. There are issues bigger than transportation that should be solved first, if we are to stick with a minority government.
