Woodlands bus interchange is already integrated
- with Woodlands MRT Station above. The most is to retrofit it with
fans (similar to the elevated MRT Stations) (I understand it is very hot inside the bus
interchange. a simple solution is to install fans), add
1/2 more escalators, re-paint the walls, re-tile the floors,
etc.
According to URA's 2013 Draft Master Plan, the site around Choa
Chu Kang MRT station - presently consist of the existing
Choa Chu Kang Bus Interchange and that empty plot
of land opposite it - is a Reserve Site: "the specific use has yet
to be determined" and "Interim uses that are compatible with the
uses in the locality may be allowed subject to evaluation by the
competent authority." (http://www.ura.gov.sg/MS/DMP2013/draft-master-plan/dmp13legend.htm#30)
Similar to the one at Woodlands, I understand the atmosphere
inside Choa Chu Kang Bus Interchange can be very hot, at night.
Hence, for now, a cheap solution is to install fans in the bus
interchange.
In future, I think this is how Choa Chu Kang Bus Interchange
will be upgraded:
It's called "integrated hub".
AND LRT wont be directly connected to bus int if that's how you
phrase it.
