The 81-year-old plaque on Elgin Bridge reads:
“The first bridge across the Singapore River, a wooden one called Presentment Bridge was constructed at this location in 1823. Its narrowness limited the number of people who could use it and a ferry service existed to facilitate the crossing. By the 1840’s the road was constructed and the bridge divided it into North Bridge Road and South Bridge Road.
At the turn of the century, more business was done on the south of the bridge and hence South Bridge Road became known as “TUA PO” [big town in Fujian] and North Bridge Road as “SIO PO” [small town]. The bridge underwent reconstruction three times and the present Elgin Bridge, named after a former Viceroy of India built in 1925″.

Thought Moments 
I believe there is an error in the sentence: “Elgin Bridge over the Singapore River links North Bridge Road (Tua Por) to South Bridge Road (Sio Por)”. North Bridge Road is known as Sio Por. South Bridge Road is known as Tua Por.
I was brought to the attention of these discrepancies and visited the Elgin Bridge again yesterday. Thanks to Patricia Kwok for her comments and feedback which heritage fans would be interested to rectify the correct information about the street names of Singapore in Hokkien. The information on the plaque is correct. I apologize for my blog error and have rectified it accordingly.
I did some research on the Internet and found this reliable heritage source for interesting Singapore road names here .
