The PIE is the oldest and longest of Singapore's expressways. The construction began in 1964 and for this stretch of the expressway where this series of ten caches are deployed commenced its construction in 1991.
NTU, former Nanyang University, where it was established since 1955, is the second oldest public autonomous research university in Singapore.
This series of mini-power trail is good for those who wants to gain some quick smiley faces.
Do be reminded on the following safety pointers:
- Do not stop your vehicle on the shoulder of the expressway to hunt for the cache;
- There is a walking trail on the residential area side for you to do the caching (safety first and do not endanger others);
- Do not cross over any barrier separating the trail and the expressway – all caches are hidden before the barrier; and
- Follow all road safety sign even you are walking on the trail or crossing the vehicle lane during the caching.
Enjoy the game and have fun.
