Yes we do need the land for other usage, but as far as the
government can, it should expand on road infrastructures. The KPE
is a good example. It's a new expressway that uses those empty land
to build on. Also, a large section of it is underground, which is
another way that the government can do it.
Also, Singapore is known for building upwards. Industries are
stacked on top of one another. Housing, look no further than your
40 storey HDB flats. That will, in turn, give more land to be used
for other purposes such as building roads.
how are we going to be able to dig tunnels everywhere? the cost
and another issue, where can we build tunnels w/ pilings done for
commerical or residential bldgs?
some industries can't be multi storey cos of land usage issue
i.e. drinks factory
