Cambodia flagTransportation & Infrastructure Guide

Public transit, airports, and getting around in Cambodia

Cambodia's transportation landscape features a growing road network with recent expressway developments like the Phnom Penh-Sihanoukville E4, serving its 16.7 million population on the right-hand driving side. Key strengths include three international airports and rehabilitated railways for freight and passengers, while challenges persist in limited public transport, rural road conditions, and logistics gaps. Residents and visitors rely on buses, tuk-tuks, taxis, and domestic flights for mobility, with ongoing investments in corridors and hubs enhancing connectivity.
