I would love to see a ridesharing company weigh in on how trip volume / average trip length / average trip duration / average street road speed has been affected by the collapse. They are the only party I can think of that would have accurate data on this subject.
This article focuses on local traffic congestion, which I honestly don't think is helpful in assessing the true effects of the bridge collapse.
While at first, it may be surprising that traffic isn't 10x worse without a segment of a major highway, traffic is the flow of individuals who are aware of traffic conditions, much like traffic on the internet.
My predictions for what is currently happening in Atlanta:
* Less trips are being taken (telecommuting / not going out for dinner)
* Mandatory trips average length has increased
* Mandatory trip average duration has increased
* Average speed on street-level roads has dropped
