You can grab the double-deck buses from any other routes, you
can avoid having it lay over at Yishun Interchange, but there's
still one big problem.
Have anyone of you seen the trees along some of Yishun's roads
(especially Yishun Street 61)? Those trees are so low and so near
to the road I can't really imagine a double-deck bus go through
them - unless the trees go through heavy pruning or are removed
altogether - and removing them is not going to sit well with nature
lovers (such as myself), as well as people who will complain the
loss of tree shade.
Yishun wasn't really designed to be double-deck bus friendly -
and it's not just the bus interchange, but virtually the whole new
town.
Yah, thats exactly what i meant... most of the yishun streets
have pretty low trees...
They better not go cut trees just for 1 bus every morning which
passes by the area... i'd rather have my shade and fresh air
compared to a seat on the premium serivce.
