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.
121's route is fine, just that it has very poor loading between
NBR and Ganges Ave. Perhaps, should have routed 121 to ply Chin
Swee Rd instead of Zion/ Kim Seng Rd. At least Chin Swee will have
connectivity to Tiong Bahru MRT and also it can complement 174
betwen Outram and Chin Swee.
As for 120, I think if it were to routed the way you suggested,
it will lose the popular Alexandra - Redhill connection. 120 is the
only service from Alexendra Retail Centre and Redhill MRT and its
loading is high along this stretch during peak hours. Also, it will
lose its connection to Telok Blangah MRT which many Telok Blangah
Dr/Heights residents rely on. Better to leave 120 untouched in my
opinion.
