Round Trip Around the Island

How do u get about the island going through all the expressways?

Enter the ECP through Singapore Expo
Continue onto the AYE at Sheares Bridge
Head towards Tuas into the KJE
Leave via the BKE at Woodlands
Go into the SLE at Yishun
Transit into TPE at Jalan Kayu
Back into the PIE at Changi

and voila.. we are back onto the ECP

So how do we add the PLE into the equation? I wonder....
