Yes, very odd indeed. One thing to bear in mind that is essentially a private road and the mall can easily reconfigure it to whatever it wants. So its weird that the column for a Skytrain Line is designed to accomodate a roadway that is never going to be permanent. Just look at Brentwood today and see how they easily tore up the roadways and parking lot there for the redevelopment. Lougheed Mall will also experience something similar eventually....

You mean like a massive dip in the Expo Line guideway for a viaduct that might be torn down?

No kidding, eh?

Although to be absolutely fair, you could have a standard column by Coquitlam Centre's curved road and it could still work. Maybe the mall can adjust the road now (even if EGRT pays for some of it, since it won't be that expensive). But for the dip at the George viaduct, you either have that massive dip or no way the Expo Line could cross at all without going at grade or above the existing structure.

Besides, I'm sure Translink will hire some highly paid artist to think of a way to add some artsy fartsy structure to account for the dip.

Well, they also tear down buildings that are in the right-of-way instead of building around or over them (like at the tunnel portal or around the Andres lands in Port Moody) - White Spot being the exception.

I wonder about that too. Seems like a waste of space...

so any answers

EDIT: Wait, this section is a little further than where I'd normally think the overpass would go...

From the official Evergreen Design and Construction documents, Schedule 4, Appendix A, page 152:

The Murray-Clarke Connector

That makes total sense.

Can you provide a link to that reference? I can't seem to find the official document on the Evergreen Line website.

[officedweller]

Thanks.
Having a hard time seeing where the guideway is on the diagram, but I guess there's a column footing between the guideways and the long gap allows them leeway in placing it.

In the Murray-Clarke drawing, there is also the "future station" shown, so that may be why the tracks are configured this way.

[officedweller]

Interesting.

Seems too close to the other station for another station (and I thought the West Port Moody station would have been in the middle of the Andres site (i.e. elevated), but I think you're probably right in terms of column support for a future Murray Clarke connector - this leaves lots of flexibility.

Seems a odd waste of space and by hoarding all the room under the Moody overpass, Evergreen precludes the possibility of a bike lane from Port Moody Station connecting west to Clarke Street.

Port Moody envisions a future bridge across Evergreen and the CPR at the foot of Kyle Street west of where the EGL tracks finally converge. See Map 11 on page 109 of the draft Official Community Plan here:
http://www.portmoody.ca/modules/showdocument.aspx?documentid=6803

It's a bit of a sore point in PoMo politics, but the 3rd station will emphatically not be built at the Andres site. If and when it comes to rwality, it will be somewhat west of Queens Street, barely 1000 metres from the WCE station.

Evergreen is being built to accommodate a version of the Murray-Clarke connector that was rejected long ago. It's a sore point in PoMo politics...

[officedweller]

Thanks for the info and link.

The webcam is on the Moody St. overpass, and the distance to the Port Moody Station
and the distance to the diverging tracks in the west look about the same
- so that based on the map, the divergence looks to be around Kyle St.

It likely diverges for supports for the Kyle St. overpass (yellow arrow),
and then they kept the single guideway alignments straight until the pocket track,
to avoid unnecessary converging and diverging.

I guess 1000m is better than Lincoln Station versus the next closest, which is I think 600m?

Here's a photo I took at the foot of Kyle Street almost a week ago, but never got around to uploading it until now.

At this point, the eastbound and westbound trackways are very close together - they converge close to Mary Street.

Aesthetics of the new transit line are not improved by the 3-metre high "blast wall" alongside the CPR.

Thanks for the pics.

Thanks.

All I can think of is if the road might curve to reduce the grade, but it doesn't look close to the divergence at all in that pic.

In the drawing the evergreen "future station" would be located north of where Queen St would intersect with Clarke.

[Olden Retreiver]

I haven't spent a whole lot of time around them or under them, but I like the look of the elevated sections with precast beams through Port Moody better than the box-girder segments along North Road. They have a lighter, airier feel.

Was in Coquitlam last weekend and it was great to see the progress so far. Can't wait to give the Evergreen a ride when it opens in a few years.
