I REFER to the report, 'S'pore manhunt holds up travellers' (March 11) and suggest the authorities set up portable toilets beside the jams leading to the Causeway.

As a resident of Woodlands Park, I saw many truck drivers caught in the jam for hours and the drivers often sound their horns late at night to register their unhappiness. The wait is already unbearable and the lack of toilets along the way could have a devastating effect on their health too.
