Slot car highway overpass

Be gentle with me on this, the files are all a mess, the design is constantly being adjusted as it is being created as part of a HO scale train with a slot car.

The design was made off of the Gardiner highway in Toronto Canada (although this one is in better shape), it was made for older Arturo slot car system.

If you print on end you can usually get away with no supports, lots of surface area so rafts shouldn't be needed either.
