My guess is that they introduced 983 in order to maintain the link
between Ave 5 and Ave 4 (which makes some sense as there are
schools along Ave 4). And there need to be a service that goes into
Keat Hong Close, so there cannot be only a trunk service to BPJ as
you proposed. Just saying
983 will serve with 172 route aft new busstops at CCK Ave 6
outside Keat Hong Close, then towards ITE with 67/188 and follow
187 thereafter to BPJ... Brickland Rd so far dun have a right turn
to new CCK Ave 6 if heading towards CCK...
Below is what i suggested using Brickland Rd, but if you zoom in
and look carefully at that junction on the map, it didn't have the
right turn... The very possible route would be the yellow line
continuation towards BPJ...
Service 983 [Choa Chu Kang Int <> Bt
Panjang] (LOOP)
- Pair of new bus stops already shaped near Keat Hong Close
currently, that will possibly make way for future 983 extension
(labeled with orange line as indication in the
map)
- To make up the speed along the route, it'll will ply Brickland as
a suggestion for now, so that pax can head back to their estate in
a shorter time
