这个问题我实在不太清楚,查了一下 wikipedia,上面是这么说的:The Singapore River is approximately three kilometers long from its source at Kim Seng Bridge to where it empties into Marina Bay and finally the Singapore Strait; the river extends more than two kilometers beyond its original source at Kim Seng Bridge as Alexandra Canal, as far as the junction of Commonwealth Avenue, and after that there is a break all the way until Buona Vista, where it becomes Sungei Ulu Pandan and goes into the Sungei Pandan.看意思好像是源头是在 Kim Seng Bridge 的位置,之后又向上延伸了2公里,那附近我也没去看过。
