If service 153 is to merge with service 274, service 153 will
ply Henderson Rd, Depot Rd and Alexandra Rd before continuing with
current route to Hougang Central. However, Depot Rd seems
impossible for a DD to ply due to the trees there, which may mean
service 153 may become a SD-only service.
I have this suggestion, since service 51 and service 186 duplicate
route between Queenstown (C'wealth Ave) and Havelock Rd/Upp Cross
St, service 186 can be amended via the following route:
St. Michael's terminal, roads in St. Michael's, Balestier Rd,
Thomson Rd [Express], Whitley Rd, Bt Timah Rd, Farrer Rd,
Queensway, C'wealth Ave, Alexandra Rd, Depot Rd, Henderson Rd, Bt
Merah Central [Express] and Bt Merah interchange.
Between Balestier Rd and Shenton Way, there is service 130. Between
Whitley Rd and Shenton Way, there are services 605 and 700. Between
Queenstown and Shenton Way, there is service 970.
