From The Daily Mail…
Chinese workers are building a 3ft-wide road made of wooden planks on the face of [a cliff] that’s thousands of feet high.
Once finished, it is hoped sightseers will flock to here to edge along and admire the views.
The “road”…they’re assembling is on Shifou Mountain in Hunan Province and stands vertical at 90 degrees without any slopes or alcoves.
