The routing of 120/121/122 has been rubbish. Whoever did these
routes did a very bad job. I agree there should be connection
between Telok Blangah Heights to Tiong Bahru and this could be
achieved by better routing of 120.
ideally 120 route should have been:
HarbourFront -- Telok Blangah Road -- Telok Blangah Dr/Heights
-- Henderson road -- Telok Blangah Way -- Lower Delta road -- Jalan
Bukit Merah -- Kim Tian road -- Tiong Bahru MRT -- Lower Delta road
-- Alexandra Road -- Tanglin road -- Kay Siang road -- Margaret Dr
-- Queenstown MRT -- Dawson road -- Kay Siang road & back.
1 service would cover 120-121-122. It will be high loading
servixe that can be operated at 07-10 mins interval. It would also
connect Dawson that has been ignored. 124 in turn could be extended
to Bukit Merah Inteechange via Telok Blangah Heights.
The routing of 120, 121 and 122 are as such because the bus
network at Bukit Merah area is already well established. (After
all, that area is right outside the city centre.) The new routes
are configured to create new bus connections, while limit the
duplication of resources.
