I don't live in Changi, but I go there often.
Currently, there are many services to the Changi Village/Changi
Point area, numberly 2, 9, 19, 29 and 89. I think 5 bus services
are enough for this area.
The introduction of services 3, 38 and the diversion of services
28, 29 are results of Tampines residents' feedback to their MP to
request for changes to the services.
