How would you think the MRT track would go from Farrer to Holland
to Buona Vista? Along Farrer Road, Holland Road, North Buona Vista
Road? or Along Farrer Road, Holland Road and cut through Holland
Drive estate?
it is expected that the tunnels will go through Holland Drive
Estate direct from Holland station to Buona Vista station.. if u
use a ruler and see on a SLA street directory, the tunnels can
travel straight out of Holland Village station to reach the
junction of North Buona Vista Rd and Commonwealth Ave before
turning a little to align with Buona Vista station's orientation..
MRT tunnels can travel straight through the area is because, one,
the whole area is state land and the govt have control of what can
be built there, two, they know exactly how the foundations of the
HDB buildings are and so are able to dig correctly if correct
engineering principles are applied, and three, the first blocks of
HDB apartments it meets actually resides on a hill which gives the
tunnel a safe distance to descend downwards towards Buona Vista
station..
as for Farrer to Holland section, it is expected to cut through
from Holland station in the exact orientation until Leedon Rd and
align itself somewhat along Leedon Rd before turning under Farrer
Court apartments to reach Farrer station.. Farrer station's
location is chosen at the lowpoint of its surroundings so its
tunnels are as deep as possible to cut through Farrer Court and the
private estates in the stretch of land between Holland Rd and
Leedon Rd.
As for Buona Vista station, why wouldn't it be built next to the
vacant land near current BV station? Rather LTA had chosen to build
at the road divider.
Building stations on road dividers is, as i said, developmental
control in that underground stations will not be subjected to
factors that may disrupt its operations and to save land space.. it
is not rare at all in Singapore.. the following stations are built
deep and right under the road divider: Bugis, Lavender, Newton,
Braddell, HarbourFront, Outram Park, Chinatown, Little India,
Farrer Park, Boon Keng, Potong Pasir, Woodleigh, Serangoon, Kovan,
Buangkok, Museum, Convention Centre, Millenia, Nicoll Highway, Old
Airport Rd, Tanjong Katong, Paya Lebar CCL, MacPherson, Upp Paya
Lebar, Bartley, Lor Chuan, Marymount.. the land around Buona Vista
is too precious to the govt as it will be used for One North hub..
similar to Paya Lebar, where LTA had to divert traffic and mess up
the whole place jus so that they could dig the station box right
under Paya Lebar Rd so the land north of Paya Lebar can be
redeveloped instead of putting a station there.. and stations that
are not under the road divider do not have any built-up areas above
them, like Tanjong Pagar (green space), Raffles Place (green
space), Dhoby Ghaut (green space), Somerset (Stamford Canal),
Orchard (green space).. only Tiong Bahru and Novena (shallowest
depth of 11m) have redevelopments coming up right above the station
box after the station was built and commissioned..
