If Haig Rd is DD-friendly, 31 should be amended to ply Haig Rd
instead of Tg Katong Rd. The latter has various other services like
10, 30, 32, 43, 76, 135 & 197.
30 can ply Haig Rd in the direction of BNL. 76 can ply the full
stretch of Haig Rd in the direction of YCK. Towards Marine Parade,
it can ply Dunman Rd then Haig Rd.
I think it is a good suggestion. 76 can ply the whole stretch of
Haig road considering you have 43/135 to ply Tanjong Katong
road.
It would suggest to route 32 through Dunman and Haig road ,
since you have sv 10 covering the Tanjong Katong - East
Coast stretch and you will have 10, 31 from Tanjong
Katong to Dakota.
This way with 76 you provide connection between Paya Lebar
stretch and Haig, and with 32 you provide connection with Kallang,
Dakota and Haig. In the other direction, you will provide
connectivity to Parkway Parade and East Coast road.
I will keep sv 30 the way it is.
