Judging from the map, the housing areas at {Yung Sheng Road, Yung An Road, Yung Kuang Road}(basically, those
along Corporation Road) , Jurong West Street 52, 41 and 42 have weak bus connection to Lakeside MRT
station. I am quite certain that the new BSEP bus route
will serve these areas. The pair of bus stops at Lakeside MRT station is
definitely served by the new bus route, unless a new pair of bus
stop is created at Yuan Ching Road, at where there was previously a
taxi stand.
Personally, I foresee changes to a few bus routes. It is quite
likely that 335 will be re-routed, possibly shorterned to Chinese
Garden area - serving Jurong East Street 31 and 32, unless there is still
demand for bus link to Chinese Garden/Jurong East from Jurong West
Street 52/41/42 even after the new BSEP bus route is
launched.
Meanwhile, 334 is likely going to remain the same, otherwise
being re-routed and lengthened to serve Jurong West Street
52/41/42, to compensate the link loss due to 335 being
re-routed, if there is still
demand for bus link to Chinese Garden/Jurong East from Jurong West
Street 52/41/42 even after the new BSEP bus route is
launched.
I am writing this on the assumption that the new BSEP
bus route is a feeder service, providing bus connection to Lakeside
MRT Station from areas that currently have weak/no bus connection
to the nearest MRT Station.
