SINGAPORE - Car drivers will have to pay $1 more at two Electronic Road Pricing (ERP) gantries during their morning commute from next Monday (May 6).

Those heading for the city on the Central Expressway (CTE) will have to pay $2, up from $1, at the gantry before Braddell Road between 8.30am and 9am.

As for those using the Kallang-Paya Lebar Expressway (KPE), their ERP charge on the stretch after Defu Flyover will increase from $3 to $4 between 8am and 9am.

The Land Transport Authority (LTA) announced these changes on Monday, after completing its quarterly review of traffic conditions on roads and expressways.

Rates are adjusted to achieve an optimal speed range of 45kmh to 65kmh on expressways.

The LTA will conduct its review on ERP rates again in May for the June school holiday rates.
