Too bad it's rarely done...the public backlash isn't worth the benefits. Even temporarily reducing the amount of lanes to speed up construction is a tough call for many projects because no one wants their commute to get a couple minutes longer for a few months.
So we get projects where the timeline drags out a bit so we can keep traffic moving on the bridge at the same time. The Bow River bridge on Stoney in the south? Yeah, that one's weird. The other two, though? I'm not sure how you speed them up without upsetting people more.

Bridge rehab is interesting, especially above a busy area, because you have to do it “gently”, which is slower. Lots of safety setup to do, to prevent broken pieces from falling down, and also to prevent workers from falling. Curves in both the X and Y axis - means that it’s hard to mass produce the pieces you need to fit, every part is a bit custom.
