Model Train concrete double arch bridge

Another old model that I built on a old train layout and was designed before Bambu was a thing. Model is 22" long when completed, needs to be glued together although it could probably be designed in less pieces and laid out differently so as to print with less assembly, I've included the sketchup files if someone wants to take this on.Like my other model I'd suggest going 0.16 or 0.12 layer height, 0.4mm nozzle will be fine for the amount of detail in this model.
