The structural integrity is not compromised by just chunks of concrete breaking off. The Gardiner Expressway uses steel reinforced (rebar) concrete to hold it up. It becomes dangerous when enough concrete falls off to the point when the steel reinforcements are exposed. At first, it may not be dangerous, however, if left exposed for long enough, it can possibly collapse. The Gardiner Expressway has many columns that hold it up, so if the engineering is good enough, just one column should not cause the whole highway to collapse (hopefully). The steel bear the tensile stresses (which concrete lacks) within the structure and help resist forces like bending and tension. Concrete primarily serves as a protective and compressive element. It surrounds and encases the steel reinforcement, providing compression strength. Concrete is strong in compression, which complements the tensile strength of steel. And protection from corrosion. Concrete covers and protects the steel from environmental factors such as moisture and chemicals, which helps prevent corrosion.Honestly, I know the cosmetic problems don't affect the structure, but every time I look at the older parts of the Gardiner, which chunks of concrete falling off, I'm astonished that it doesn't just collapse.
The walkway between Yonge & Bay has pretty much been open all the time now - they sometimes close it for a few hours if lifting stuff over it but for last few months I think I have never seen it closed. The section that is open all belongs to the Dominion Public Building as far as I know.The passageway on the north side is now open at Bay thus giving great access for people like me! Lol

As someone who uses this route a fair amount, I sure hope the hardscaping and landscaping for CIBC includes this area owned by others. It would look awful if not completed with CIBCThe passageway on the north side is now open at Bay thus giving great access for people like me! Lol
