THE six additional Electronic Road Pricing (ERP) gantries slated to come onstream in November may not be built all at once, said Transport Minister Raymond Lim yesterday.

Speaking at a Singapore Press Club luncheon, Mr Lim said traffic flow on several roads in the city has improved since the Land Transport Authority (LTA) unveiled a slew of ERP changes in July.

'If this is sustained, then LTA will be happy to review the plan,' the minister said. 'It may then need to put up only a few gantries rather than all six.'
