The West Coast Expressway (E32), abbreviated WCE, is an interstate controlled-access highway running along the west coast of Peninsular Malaysia. The 233-kilometre (145-mile) expressway is currently under construction, with several sections open for public use. Once completed, the expressway will run between Changkat Jering, Perak and Banting, Selangor, following federal routes 5 and 60 for most of its route. The expressway will operate in three sections, with sections of federal route 5 completing the missing connections; these sections will be upgraded to limited-access roads. The expressway is expected to be fully completed by the end of 2025, except for a 10 km stretch from Section 7B which is expected to be completed by June 2026.

Federal Route 5 is one of the three north–south oriented backbone federal roads running along the west coast of Peninsular Malaysia, Malaysia. The 655.85 kilometres (408 mi) federal highway runs from Jelapang, Perak in the north to Skudai, Johor in the south.
