Motorist Lim Quan An used to take the Kallang-Paya Lebar Expressway to get from his home in Loyang to work in Alexandra. But since ERP gantries on the KPE were turned on last April, the 34-year-old compliance specialist has switched to using the East Coast Parkway.

"Traffic is moderate. And I time myself to pass the Keppel exit after 9am," he said, referring to the only Electronic Road Pricing gantry along the route which he passes.
