Upp Changi Rd was once a long stretch of road from New Upp
Changi Rd to Changi Point (current Changi Village). The current Upp
Changi Rd North/East and Changi Village Rd are called Upp Changi Rd

disappeared stretch in Bedok town to Anglican High School, then
continued along the current stretch to Simei Rd, then continued
along Upp Changi Rd East, Upp Changi Rd North to the junction of
Loyang Way (near Selarang camp), after that it aligned to the right
and continued on the present "slip road" of Upp Changi Rd North,
passed by Calshot Rd and then continue via the present disappeared
stretch and meet up at the end of present Changi Village Rd, then
again passed by Tangmere Rd and continued to end at present Changi
Village.
New Upp Changi Rd back then ended at the junction with Tanah Merah
Kechil Rd. Chai Chee St and Chai Chee Drive was one road from
Siglap Rd/New Upp Changi Rd junction to Upp Changi Rd.
