practical intervention with minimal interruption
i feel that we should keep the corridor as "wild" as possible in terms of path and greenery, and allow the visitors to the corridor use it to the limits of their imagination, and appreciate how amazing it already is.
rarely in singapore do we have a true "trekking trail" that is so ready-made and nicely furnished with nature yet set in an urban environment.
by this, i mean that while rest stops and toilets are indeed practical, they shouldn't overshadow the nature and the corridor itself.
furthermore, i think the "heritage" aspect of the corridor is important and should be emphasised, but maybe in a museum, and not on the corridor itself unless it is tastefully done either in simple metal plaques. signboards with photos often fade and get very ugly (i spent a lot of school field trips thinking thinking about this)
