I'm beginning to think that ramp will not be levelled out, given how the columns and beams supports it (based on what you can see in the video). I think they will somehow incorporate it with the guideway design so there will be a little incline. But I'm not the engineer so I guess we'll find out it a few weeks.

That small incline of the unused Evergreen track is a result of the 'ALRT' planning for a connection between Vancouver and Coquitlam. With all the stops & starts & changes to the 'ALRT' project - including using LRT instead of SkyTrain - once the decision was made to use SkyTrain, the only way to build it within the budget was to only build from New West via Lougheed to VCC. At the time of the Millennium Line construction there were still plans to have that future segment to Coquitlam do a 'twist over' itself during the curve from Lougheed Stn, over White Spot and into the North Road centre median so the Inbound and Outbound tracks are on the 'right side'.

Apparently the current plans are to eliminate the 'twist over' of the tracks and build them as normal (side -by- side) elevated tracks along the curve, so if the existing incline is left in place, the new track guideway will likely be lowered again to be level with the rest of the new guideway. the "Evergreen hump" may become just another 'quirk' of the Skytrain system. This may be cheaper than chipping out the two segments that start the incline and installing new replacement guideway segments that are level with the rest of the guideways in the area.
This implies that the Inbound and Outbound trains between Lougheed and Burquitlam are 'wrong railing': the Vancouver -bound trains are using the tracks on the eastern side of the North Road median, and the Douglas College -bound trains are using the tracks on the western side.
There will be cross-over switches south of Burquitlam Stn that all trains will have use to get to the 'proper side' of the Burquitlam platform: Vancouver -bound trains will use the west side platform and switch over to the eastern tracks, and Douglas College -bound trains will use the western tracks and switch over to the east side platform.
Between Burquitlam Stn and Douglas College Stn, Inbound trains will use the western tracks, and Outbound trains will use the eastern tracks, so trains are running on the 'right side' again
