Heelloo! As requested, here's a short guide on going to IMH.
Basically there are a couple of buses you can take, namely 156,159,325 or 88.
156 and 159 can be boarded from sengkang interchange.its journey will be shorter as compared to taking 325, as 325 is a feeder/loop service that travels arnd hougang.Since IMH is at the tip of the hougang/sengkang area, 156 and 159 just travels straight down there,spotting IMH shouldn't be a problem!^^
88 u must be careful when you alight cos it will turn into YCK primary.
for bus 325, which i believe most of you all will take,it will come from hougang interchange.But here's the catch..taking it from the interchange will mean a big loop arnd hougang area, and u find urselves passing by hougang MRT again!its allright if u wanna play safe, but for those who hates delay then here's it... remember to walk out of the station from the exit which is in the middle of the field(the exit that has the control station nearest to it).u can see the nearest bus stop there.check that it has 325 on the stop,then cross the road to the busstop opposite,which has the canal near it.then take 325 from there!!^^
Yeap thats it.any problems just give me or mingkwang a call! we'll be glad to help!!!^^
