The left side of this photo shows the underside of the York street ramp to the east bound lanes of the Gardiner Expressway.

This long ramp has recently had its complete steel and concrete under structure craned into postion in a number of sections. Now the deck and side concrete wings are being added.
This structure was worked on even as the Parliament St area of the Expressway was having it deck and steel structure replaced.
This double effort seems to be available to the contractor AECOM as their purpose built sheds a few blocks away can cast concrete on to multiple prebuilt steel under decks at the same time.
