Time on site seems like a massively critical time variable, especially with infrastructure people want to use, e.g. a road/highway. Time off site is presumably much cheaper, certainly less disruptive.
The title feels informative to me.

All in all that's a pretty low amount of time; often these are done by closing the road under for an unspecified amount of time, diverting all traffic onto one bridge span (reduce to one lane in each direction) and replacing the bridge a half at a time.
So all that matters is people watching it on TV?
I disagree much, because building site was there for months and road below was hindered all the time. Highway was maybe operating without closing lanes but that is not the full story there.
