History
Stone side of the viaduct. It's visible the reinforced concrete bridge added to the original stone one.

When built in 1851, it carried a double track of the original Baltimore and Ohio Railroad main line. In 1916 the viaduct was widened to accommodate two more tracks. The addition is a Melan-type reinforced concrete bridge of identical configuration built against the south face of the original stone bridge.[2] As the state boundary follows the southern bank of the Potomac, nearly all of the bridge is located in Garrett County, Maryland.

The Bloomington Viaduct was listed on the National Register of Historic Places on November 21, 1976.

gollark: The 350M one doesn't seem to exist and I can't really work with anything bigger.
gollark: This is annoying, apparently 6GB of VRAM isn't enough to finetune the 125M GPT-Neo even with a batch size of 1. I might just use Colab.
gollark: Geese are fearsome beings.
gollark: It would take ages to download so I'd prefer not to if it probably won't work.
gollark: Speaking of somewhat underpowered hardware, can I use the 2.7B GPT-Neo model on my RTX 2060 (6GB VRAM) in half precision? Multiplication leads me to think it's possible just considering the parameters, but some internet things imply it won't work presumably because of storing other stuff.
