Electronic Road Pricing (ERP) charges at certain gantries along the Central Expressway (CTE) and Pan-Island Expressway (PIE) will be adjusted from Monday. Motorists using the southbound CTE before Braddell Road between 9am and 11am will not have to pay ERP charges. They currently pay 50 cents. Those using the PIE slip road into the CTE between 7.30am and 8am will pay S$3 - 50 cents less. However, ERP rates for four gantries along the southbound CTE after Braddell Road will go up. The rate will increase by 50 cents - from S$1.50 to S$2 - between 7.30am and 8am. Between 8am and 8.30am, motorists will have to pay S$3, an increase of S$1. The Land Transport Authority said yesterday that it adjusted the rates as part of its quarterly review of traffic conditions on ERP-priced roads and expressways. The next ERP review will take place later this month for the June school holidays.
