Why haven't both Singapore and Malaysia considered the option of a ferry service between Singapore and Johore Bahru ?
Maybe it's time for Singapore to build a new jetty at Pasir Ris since this is where the army boys will fall-in - yes, they fall in at the bus interchange. The army buses will then take them to Changi jetty for transfer to Tekong. Just build a new jetty at Pasir Ris and connect the MRT with the new jetty.
The new jetty should also offer ferry service to Johore Bahru just like the ferry services between Hong Kong and Macau. Or Singapore and Batam.
