Toronto Ontario Line 3 | ?m | ?s | Metrolinx

Those cross beams look like the permanent ones and not just temporary ones for construction? cc @crs1026 @smallspy
For the East portion of the portal (~1/3 of total length) there will be 3 layers of struts & bracing, the top 2 layers are permanent.
For the rest of the portal there will be 2 layers with only the top one being kept permanently.
 
Why are the struts exposed instead of being covered with concrete? I assume it would be better for rust proofing

If they are like all the other struts in recent projects, they are a metal that will gradually oxidise to rust red, at which point the oxidation stops and they do not need further rustproofing.
