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.
...Nathan?
What arch type would this be classified as?
Also another fun fact about this bridge, this bridge was extant before lincoln way (then called boone street) was even paved
