In Pictures: Electronic Road Pricing through the years

The Electronic Road Pricing (ERP) system which Singapore motorists are familiar with will soon be a thing of the past when an islandwide model with the ability to charge for distance travelled is rolled out from 2020. Here's a look back in pictures at the gantry-based ERP system that has been in place since 1998.
