Millennium Line - Evergreen Extension | Completed

I know that they could have built dual beams that would have been more aesthetic if they removed the ramp - but it was likely a question of cost vs aesthetics.
I think the decision to use dual beams (i.e. TCH crossing vs Lougheed crossing) may depend on the radius of the curve.
It seems that most of the other sharp corners on the system are dual beam, but in those cases, they also lead to centre platforms - not sure which reason would have governed in those cases (if either).
