Back on this island, an almost similar structure crossing a waterway can be found near this geo zone; you may take a walk around the structure and there is jogging path nearby.
This is part of the Jurong Malaya Railway (KTM - Keretapi Tanah Melayu) Line which was constructed in 1965.
It was an extension from the Bukit Timah Line and it was six-mile long to serve the Jurong Industrial Estate by rail.
Enjoy the scenery and have fun in caching.
