Transportation & Infrastructure Guide in Cambodia

Basic public transport limited to Phnom Penh City Bus with 13 routes; no metro or urban rail. Regional buses and two main railway lines (Phnom Penh-Poipet 385km, Phnom Penh-Sihanoukville 257km) offer infrequent services. Poor integration, limited coverage outside capital, and reliance on private vehicles/motorbikes.

67,900 km road network (70% rural), with major highways paved and upgraded to international standards. Phnom Penh-Sihanoukville Expressway (190km, opened 2022) and Phnom Penh-Bavet under construction (2023-2027). Good maintenance on key corridors like AH21, but rural roads prone to flooding; ongoing Chinese-funded expansions.

Average fixed broadband speeds around 65 Mbps, with mobile averaging 45 Mbps as of early 2026. Fiber expanding in urban areas like Phnom Penh and Siem Reap; rural connectivity lags via 4G. Investments in smart logistics support improving infrastructure.

Avg: 65.2+ Mbps • Available in major cities (Phnom Penh, Siem Reap, Sihanoukville ~40% coverage), expanding via government and private initiatives

17 airports, 5 major including Phnom Penh (PNH), Siem Reap (REP), and upcoming Techo International Airport (2025) as Southeast Asia's largest for cargo/passengers. Good regional links to ASEAN, Thailand, Vietnam; growing international routes to East Asia, Europe, US.
