Just look at the Spadina Extension in Toronto and how long that project is taking. And half of the stations are being built in the middle of nowhere. But it is underground.

Well if they insist on learning the hard way and doing it as a bored tunnel, I hope they just go as far as Arbutus and leave the section to UBC up for discussion.

Oh, and invest in your local water pump supplier....

Besides the almost certain cost and schedule boondoggle, I suspect you are talking about businesses being up and arms over the lack of access for customers.

Well, if you have a TBM down Broadway, that means the stations will be on Broadway.

If you have the stations on Broadway, you have major excavations on Broadway. Sure, the stations will be localized, but they will be virtually impassible, turning Broadway into a bunch of segments. They MIGHT be able to figure out ways to squeeze the buses buy, but say goodbye to through traffic. Everyone is going to take alternate routes.

These giant holes are going to be intercepting a whack load of utilities. Depending on how you want to tie them in you can expect a whole bunch of lane closures to deal with it going east west as well.

If they want to avoid a traffic and access nightmare, they should build it elevated!

I drove up and down North Road lots of times during the skytrain construction. Was it at full capacity? No. But I would hardly qualify it as a boondoggle, and I have yet to hear of any riots from business.

Just sayin.......

North Road is between 40m and 50m wide. Broadway is between 24m and 28m wide.

I think you underestimate how hard it would be to fit that.

The stations on a bore would also likely be offset from the street and be excavated from surface.

That's what I was hoping for also but for one reason or another not disclosed by anyone is the reason that the decision for Broadway was made.

This is going to be one serious traffic mess. Think of all the major north/south roads that will traverse the station construction locations.

Broadway's a bit too dense and too narrow for that - and how would they handle the West 10th/Alma turn?

the sky is falling!!! The sky is falling!!!

sums up that post pretty good. sounds like Jordan Bateman, make a huge deal how "all this is bad, all that is bad" when it is all just nonsense. as mentioned above, Broadway is a very narrow street, there is NO room for it to be above ground. you would need to remove 2 lanes of traffic, that means 24/7 no stopping on Broadway, not just rush hours. station construction would be just as disruptive since there is no room to move traffic around the building of said stations. the difference is you can cover a hole and allow vehicles to drive over the excavation.

It does seem like a missed opportunity to not put it under 10th. If the stations' entrances were on Broadway, you probably wouldn't have to take an escalator down a level. The stations would be level with the trains under 10th much like Canada Line's Cambie and Broadway station.

Weird.

That's exactly what i was thinking. From Broadway to 10th is a very short distance. It's probably further to transfer from the Expo line to the M line at Broadway/Commercial station than Broadway to 10th.

The more I think about it the more I think they will plan the route along Broadway as a result of what ever backroom political agreement someone came to and during public consultations realize they cant do it. Everyone else working on his project and doing the planing will just get paid twice.

I don't see how they can do any sort of tunnel bellow Broadway. The stations would completely block Broadway every 650 to 700 meters. Ignoring the complete shut down of a major arterial road and one that is part of the MRN (major road network) MRN they would have to completely re route the 99 and all other buses for probably more then 2 years while the stations were excavated. I just don't see how that is feasible for any stake holder. It wont happen and what ever plan they come out with will be quickly shut down and they will have to rework it and go to either 10th (preferred choice and can be cut and cover) or 2nd/4th/CN line (cheap choice and can be elevated along a existing ROW) to Arbutus.

I don't see any other way, Broadway cant be shut down for that long and the stations would take up it entire width and some (and there are 5 stations from Main to Arbutus in a 3.75 km stretch, each with a 50m or so diameter excavation going to a x meter depth.

This project will not be built within the next 10 years, it will be going back to the drawing board again in a couple years.

Not directed specifically to VancouverOfTheFuture but can someone explain to me why people are so possessive on the 2 lanes that would be lost if the Broadway Extension was elevated?

There will be a very fast train there, so for most people going to the area for whatever reason, you won't need to bring your car. Just hop into Skytrain and there you go. If you do need (or more accurately, want) to use a car, just use the remaining lanes or even parallel streets like 10th.

I've always supported a Skytrain extension to Broadway as long as it is SKY-Train....a train high up in the sky. People already pointed out why tunneling is not feasible, why its prohibitively expensive and why its very disruptive. You don't need to tunnel under Broadway, elevated will do nicely. An elevated train does not make a city ugly, it actually enhances its beauty. Just look at all those sci fi shows that show cities of the future, and they often feature an elevated train. Even the beauty shots of Vancouver often feature the elevated Skytrain.

So just elevate the Broadway Extension. Its easier, cheaper, less disruptive and better for everyone!

i don't think you've thought out the consequences completely of a shut down of 2 lanes. so lets say there is a median down the middle, and 2 lanes of traffic on either side.

Buses - okay, so you have buses going down Broadway. which means bus stops every block. sure, it isn't an end-all, but it is still a factor. just because a train is built, not everyone will use it. sure it will remove cars, but Broadway is way over capacity as it is. even with a lot of cars removed, there would still be a ton. i don't understand this mentality people have here of "the cars will disappear!!!!!" no, they wont. some will, but as has been shown, even with Sky-Train there is still a ton of traffic on Cambie WITH Canada-Line UNDER that street. specifically looking at King-Edward North since that is similar to Broadway.

Parking - you couldn't have parking on Broadway anymore, 24/7 it would need to be a no stopping zone. there is not enough off-street parking along Broadway during the daytime. they fill up pretty good. parking on Broadway, as it is now, is pretty full throughout the day as well. if you did allow parking, that means the street would be 1 lane in each direction. that would NOT be feasible at all.

Trucks, Cars - so, you either are left with a 2 lane street that allows no stopping, or a 1 lane street with parking. we in the real world realise that yes, transit will certainly help, but it will not get rid of enough cars to make a 2 lane street realistic. where as if it stays 6 lanes, we keep parking, and we also have a lot less gridlock. and i am sure i don't need to tell you that idling cars pollute A LOT more then moving cars. it also gives the option to keep no stopping zones during rush-hour and IMPROVING traffic flow. why is everyone here against improving traffic flow?????? that means less time idling, less pollution, less stress, a faster commute home, less adverse health effects.

The Guide-Way - assuming it goes down the centre of the road, in a median, you are talking only about 10m from either side of buildings along Broadway. you are talking commercial offices, Drs offices, housing, etc. if it is on one side, then you are talking right on the windows. Chicago EL anyone?

Construction - you really think building a station above ground will be LESS disruptive? no, it wont be, not enough to be material anyways. there is no room for staging other than on the physical road space, buildings have no set backs. with boring, you only need to deal with the stations. and there are ways to dig down, and cover the hole so that vehicles can still drive over the hole while they do their work underneath. wouldn't be the first time that is used, and wont be the last I'm sure.

Other Streets - where else could the cars go? 4th is too busy, 12th is too busy, 16th isn't all that big of a street. 10th is for bikes and the CoV is making it that way on purpose, they are discouraging cars on it. that is a trend that will continue. it is the busiest E/W route in the city for bikes. also, 10th is ALREADY a mess as it is.

The View - what view? you mean those tiny little slivers as you pass over the N/S streets? in that "very fast train," how much of a view will you get over those streets? 1.0 second? 0.75 seconds? other then that, you'd be staring into the buildings that i mentioned above in "The Guide-Way." windows upon more windows of all kinds of offices and housing.

Sci-fi Reasons - seriously??? "hey lets do what Hollywood does because that's realistic right?" why do we even bother having people in the planning field? we can just go by what Hollywood does since if it is good for them, it is good for us.

"It's Easier" (this one will sound like a bit of a preach, be forewarned) - the worst reason of them all i think. it screams of mediocrity and shortsightedness. that is like the Canada-Line. it was easier to build short stations, single tracking, and omitting stations for the future. and look at that, it'll bite us in the ass later. building it underground, that is forward thinking. that is saying, "Broadway might be changing in the future, at some point, lets not hinder its prospects because it is easier, lets do what is harder, but the right choice."

doing what is "easy" is not how we become better. if we did what you said, and did what was "easier," we wouldn't have even half of what Western Society has built. we wouldn't have skyscrapers, air planes, we wouldn't have landed on the moon. we don't get better by doing easy things, we become stagnant.

^don't forget a whole stretch of properties will have to be bought out/demolished just to connect VCC/Clark.

Anyone who thinks this should be elevated is not thinking this through. Going elevated will be MORE disruptive than going underground, and the effects are permanent.

^As you spend more time on this thread you'll learn that there is a vocal strain of forumers who tend to view this project socially/politically more than practically. Of course it is possible to build the line above ground, but for a myriad of reasons (literally dozens), it is much more practical, despite the costs, to build it underground.

But there are some who think that the only reason this is being built underground is because it is Vancouver, and that Vancouver thinks it's special and deserves fancier things than the suburbs (as opposed to the actual, logistical reasons). I would argue that some even see an elevated line as a way to "punish" the relatively wealthier residents who live along the busy sections by blocking their views and "forcing" them to have to look at concrete pillars just like the "average joes" do in the suburbs. Again, missing the actual reasons for it to be underground.

Seriously? Surely parking can be done inside the buildings since they have parkades. Or are you just too cheap to pay for it and would rather pay via quarters parking on the street? Very car centric reasoning.

Again, very car centric reasoning. As for trucks, they can deliver during the night, and most do so anyway. Courier trucks can do so at the back.

Based on the recent experience with the Evergreen Line, yes its not so disruptive at all. The columns tend to have a small foot print and thanks to gantry cranes, segments can easily be hoisted in a quick and timely manner with little disruption to traffic. For underground, people has already pointed out how disruptive it is. Even if bored, you still need to deal with the stations. We've seen it in Canada Line, and even the Evergreen Line tunnel how disruptive underground construction can be.

Then maybe the CoV should make Broadway be the bike street and 10th be the car street. Yes, they should discourage cars, so take away the 2 lanes for Broadway in exchange for an elevated Skytrain helps the CoV accomplish that goal

What's wrong with the Canada Line? I think its an awesome system. Granted I did not like it queue jumping but what's done is done. Its there so might as well enjoy it, right?

...and yet Canada Line stations were built on the most congested portions of Cambie while maintaining at least some traffic lanes in each direction. Was it traffic hell? Sure. Did they do it? You betcha!

Yikes!!! Sure I know it's cheaper, but are you advocating ELEVATED SYTRAIN DOWN BROADWAY? People fuss over viewcones and such, but an elevated guideway would sure as shootin' grotesquify the city! Call me a nimby if you want, but for me, that idea is visuallyhorrible. Others will call for it, I know. They want to see the pretty view - and cut costs, of course. But this ain't Chicago, and is much smaller and aesthetically much more fragile.

ps: When BART was built under Market St in SF, they had temporary ramps to accomodate surface traffic, as I recall, though I was very young. I seem to remember them made largely out of wood (with temp reinforcements, no doubt).

Rightly or Wrongly, the subway (below grade) is the correct choice when you want to preserve "views" or plan for the future. If this means some short-term pain (the pain is worse for surface LRT's, which render the entire street unusable to install or rip up tracks and utilities) then it's preferable. Vancouver's population isn't going to just stop dead once it's built.

You can not have it both ways, rapid transit and stay low density. That makes the transit uneconomical (surface rail is always uneconomical, when you put it above grade at least it stops being an accident magnet, but when you put it below grade it preserves the at-grade alignment for local bus service.)

Surrey is going to learn this the hard way when surface rail on KGB and 104 force people to take the Port Mann instead of going through Surrey. Literately the LRT is designed to trap people in Surrey. Let's flip the script for a moment and say Surrey decided to build a Subway and Broadway was a LRT...

If Broadway was a LRT, it would cut off every north-south throughfare between UBC and Clark Drive. So Highway 1A, Main, Cambie, Grandville(Highway 99,) Burrard, all get cut off. Anyone wanting to drive into Vancouver would have to take Hastings. It would be a huge disaster. If it was an above-grade Skytrain, they would likely run the track above Broadway but use low-impact pillars on the south side of the road like they did with the Canada Line instead of putting the entire guideway down the center of Broadway.

If Surrey's LRT was a Subway, then it wouldn't cut off all the north-south and east-west traffic around Surrey. But the LRT will cut off Highway 1A, Fraser Highway, and all traffic crossing KGB which means Delta is cut off except by taking SFPR or Highway 10.

So the difference, is that in Vancouver, at-grade work would cut the downtown entirely off because it cuts off all three of the north-south bridges. It would also impair North and West Vancouver traffic from crossing the Lions Gate, so there would be grid lock on that bridge and straight through downtown.

In Surrey, the LRT is going to divide the city in half. The West side will be cut off from the East side, but anyone on the west trying to go around still has the option of 128th and 108th. But likely will be perpetual gridlock, and people will be told to take SFPR to avoid Surrey entirely. While Surrey essentially is cut off by building the LRT, there is still a route around it.


Which comes back to the reason why Underground should be preferred where there are existing buildings. It impacts the surface the least. However it's not completely without issues, since the stations still need to be built, but that can pretty much be done by demolishing the buildings on either side of Broadway, supporting the road, and then excavating underneath, or the cheaper route of excavating the entire station at once and simply directing traffic around it. In the latter case it makes more sense to build all the stations foundations at the same time and restore the road.
