The other alternative would be taking the existing structure completely offline, removing the bridge decking, as was done at Roblin, widening the approached for added lanes and then building a new bridge. Removing the bridge would require a temporary at-grade rail crossing on the relatively busy CN mainline.

I was thinking a new bridge completely too, which may happen. Or just close down one side, widen it to 3 lanes and rehab. Same thing for the other side. Then push out the ramps and stuff to make it better geometry. Didn't they rebuild the piers there too with new girders. Basically new bridges.
Edit: Looking at Streetview and Roblin looks to be all brand new. And is very wide underneath.

The structure at Wilkes is for Perimeter Hwy traffic. So it's just as busy as any other spot on the south Perimeter. It needs to be rehabbed at minimum.
