New tunnel dome design

I did a tutorial showing that there are two different ways to triangulate a tunnel type structurer: • sketchup geodesic tunn...
This design is the other way, I don't normally build tunnels in this format but after seeing a picture of the network rail station at canary wharf, I thought that it could be a useful design.
I liked the ends that curve out towards the top and a triangulated tunnel will have no problem withstanding any snow load.
If you like this design or have any questions/comments about it let me know in the comments section below.
Thanks for watching.
