If I'm understanding them correctly, neither design proposal seems to be inclined to preserve the bridge: https://iastate.qualtrics.com/jfe/form/SV_agTcUOpXJPT9Gm1

Identification of a Melan or Melan-style concrete arch requires either a plaque listing Melan, a study of original bridge plans indicating Melan or Melan-style reinforcing, or severe deterioration that exposes and renders visible the reinforcing (see External Links to Flickr photos: http://www.bridgehunter.com/mn/ramsey/bh48952/ ). That being the case, I can't tell if this bridge might be a Melan arch. 1911 is a fairly early arch bridge, but other reinforcing methods were also established at this time.

I'm still an infant when it comes to concrete spans...but I'm kinda thinking it might be a small Melan arch.
