Looking east and west along Connaught Road in Central District:
Hong Kong Island is one of the most geographically constrained urban spaces in the world. The island is small and dominated by very steep hills, rising to a tall spine running its length.
Connaught Road runs along the thin strip of relatively flat land on the north side of the island, and is the main “freeway” … in the whole city, really. Space is at such a premium that the heavy pedestrian traffic moves along elevated walkways.
