Expandable bridge/aqueduct

Just something quick I tossed together, possibly going to be used for future projects. The idea is an arched bridge or aqueduct that you can infinitely chain-paste together to make something as long as you want. As usual, free anyone to use, but please give credit if it's going on a server. If you'd like to include it on a map to be published, credit must be given. Enjoy!

A note when pasting in the schematic!
Paste point is shown with the white wool in the single-structure picture. Be aware of that when you put it into your world.
