Yes, I have heard the name "Subway" used before. Structures like this seem to be known as tunnels colloquially these days.
I've seen these sort of overpasses referred to as "subways" on occasion. That nickname (Which is common in Europe) seemed to fall out of favor due to the confusion with subway transit systems.
Some of them are locally referred to as tunnels, like two in Houston, Texas are.
I noticed both this bridge and BNSF-Madison street have a wooden and concrete railing on either side.Why is that?
The Tunnel VS. Not Tunnel debate always makes me think of this structure and its twin on Madison.
Yeah, I'm not opposed to changing names of those that are colloquially referred to as tunnels to say as such, but it should be made abundantly clear that unlike the cut-and-cover construction Royce is arguing against (Despite it typifying said construction style), these aren't considered tunnels on an engineering-level.
Another example of this would be the "Awful Tunnels" in Omaha.
Common nickname amongst drivers, but neither the city nor the railroad engineering department ever considered them tunnels.
