Millennium Line - Evergreen Extension | Completed

[idunno]

It really is crazy in person to see the height of the columns at the intersection of Clarke Road and North Road (just south of Burquitlam Station). That section of track headed down to Lougheed Station is going to have amazing views to the West.

I can't wait to ride it!

Thanks!

The chunky columns near Gatineau Place are probably for twin guideways (two separate single track guideways), whereas the standard octagonal column is for the segmental dual guideway (two tracks on one guideway).

Still looks weird that the taller guideway around the curve is on the inside of the two. Presumably the outside guideway won't be banked a lot, as the clearance looks tight.

Yep, that's what I was thinking that's where the transition will happen, similar to near the Steve Nash Fitness World. Can't tell if it's steel girders all the way to the dual guideway, or steel to end of curvature, then concrete on the straight portion...

As for the inside guideway being the taller of the two, it was suppose to basketweave originally, so the inbound guideway didn't have to do much is my thought...but now that it's side to side but maintaining original elevation, it's just a quirk of the Evergreen line portion...

Up to Gatineau (the caps near White Spot), they each seem have rebar that forms a "cradle" for the steel box girder (with the initial joint at Lougheed having a ledge (i.e. see outbound 3rd platform, 2nd pic from dpogue below)). The cap of the Gatineau column doesn't have the "cradle" of rebar - so either it doesn't need the cradle (less lateral forces on the straight section) or it transitions to concrete (but still not the dual guideway type of cap).

I think the column cap west of White Spot will be formed upwards to cradle the steel box girder like this bent closer to the station:

Overall, one very ugly / dog's breakfast section of guideway from Lougheed Station to North Road.
Hopefullly there will be buildings built up around it so it isn't all that visible.

What was a very ugly / dog's breakfast was that unfinished guideway and (percieved) hump that has been at Lougheed Station for many many years. Nothing can be more uglier than an unfinished project. Once the guideways connecting Lougheed Station to the rest of the Evergreen Line is done, it will be the most significant improvement in terms of beauty in the area, regardless of whether they use steel or concrete, etc.

Came across a lot of great construction pics here:

Yeah, I saw that. That Grant Mattice is a really good photographer. I'm glad he is following the progress and using his creative skills to enhance the beauty of the construction process. If he keeps it up, I think the Evergreen Line will be one of the most beautifully documented transit project in the Lower Mainland to date.

I manage to take this photo today, January 26.



It looks like the time for them to construct a segment (guideway components between columns) is one per week.

The latest community update did indicate that the guideways will reach Gatineau Place by mid summer, so August. Essentially one year from when the first column was erected...

Where exactly is that location and how do I get there by bus?

Thanks

It's at Como Lake Avenue and Clarke Road. Looks like you can get there via the 156 or the C24 from the Lougheed Town Centre Skytrain station.

97 b-line from Lougheed would be the quickest way.

The next section will have to go over Como Lake Ave., does it take longer and do they do it at night when there is less traffic?

Here are the details for the section going over Como Lake Avenue.

It looks like the process could take up to two weeks in this case, and I can imagine its probably going to be the same when they cross over Clarke Road, Smith Avenue and Cottonwood Avenue due to it crossing above roads. I think once they are in the Burquitlam Station area and in North Road itself, the process will be a little faster due to less obstruction.

They did it at all hours of the day for the Canada Line, regardless of what was underneath (most segments on that line crossed a road or commercial driveway). It looked a little scary at times, but I assume it's safe. And it was more like 3 days per section during that project, much less than a week. New traffic lights were being connected and operational within the same day of guideway going up over intersections, etc. Really a remarkable construction process, totally at odds with the slow pace of bored tunnels.

A small update from today, will get some pictures later this week if the weather cooperates.

-The gantry is still supporting the completed second section of guideway and it doesn't look like they are ready to place it on the column just yet, there is still some rebar poking out.

-Work is being done on the top of the column in the White Spot parking lot, specifically on where the outer girder will be placed. Scaffolding is also going up around the column.

-Columns for the tail end guideway sections at Lafarge Lake have been poured, the last pair are only ~6' above the ground. It seems like it should not be long before the station itself starts to take shape.

They were under the clock, hence why it would have been quite fast. They have the Olympics deadline after all and would like to finish ASAP in case there are some "acts of God" that take place like storms and such that could slow them down.

EGRT does seem to be taking its sweet time, and I'm surprised they are still doing a lot of utilities relocation. I always thought those were done during the "Early Works"....I guess not. July 29, 2016 is still a long time to get everything up and running....

As with complicated construction like this it takes a few weeks for the crews to get into the rhythm of construction; Finishing yesterday's work left overnight to dry or cure, doing today's work, and prepping for tomorrow's tasks. Once the crews are trained and running 'like a well oiled machine', the pace of completing each segment will quicken each week.

I'm sure that timeline includes a healthy block of contingency time, which if all goes well, they can use to declare the project 'completed early, months ahead of schedule!' Champagne, smiles, and cheers etc.

[officedweller]

And from the contractor's perspective, it's negotiated with a buffer to avoid penalties.
