If you look at the rehab date... adding these arches seems to have been more popular in the 1980s and 1990s... earlier preservation efforts. I don't think they are used as often today. That has been my impression.

Another one of those spans that raises the question(s).....

Was adding arches the only way to save this bridge from an otherwise unforeseen fate........ Was this the brain-child of an insensitive and uncaring engineer...... Or was it merely the most affordable option?

I guess it's like the whole "Is the cup half empty or half full" analogy. I have tried to dull my senses a little to the pretense of there being a "right" way to do something, and just attempt to find solace in the sheer existence of the aforementioned span.

.....Now I can go back to reading about Schrödinger's cat ;)
