Now that would be a very useful idea in my county if a grapevine bridge could carry light traffic and repair its self.

I know of a 6ft wide x 4ft thick branch-bridge about 75ft up between two redwood trunks (probably reiterations of the same tree genetically). Coast Redwoods do this bridging more than any other NW conifer I know of, but I have seen maples fused to doug firs 8 ft up, and doug firs to sika spruces 40ft up.

Here is an example of living bridges in India. Any other examples in different climates?

Yes, especially in forests where there are still many interlaced strands of ceder. They form almost platforms. I have seen this work well in draws with alder.

The link is to a company (no affiliation) that does it, but the pictures are interesting to see. Since white willow will fuse just like cedar I wonder if you could make it over a wider distance by planting support beams/trees.
