Cambodia Infrastructure Map 2025: Roads, Ports, and Special Economic Zones
Cambodia's infrastructure is undergoing a major transformation as we enter 2025. The latest map of roads, ports, and special economic zones reveals strategic developments aligned with national growth goals. These updates are closely tied to recent infrastructure challenges and solutions discussed by local experts. Investors exploring this landscape should also review renewable energy opportunities and the growing role of urban planning partnerships that shape these regions.
Cambodia’s infrastructure transformation is no longer a distant vision—it’s unfolding rapidly across the nation. With strategic support from foreign direct investment, public-private partnerships, and regional integration frameworks like ASEAN Connectivity and Belt and Road Initiative (BRI), the Kingdom is reimagining how goods flow and where value is created.
This 2025 deep dive into the Cambodia infrastructure map highlights where the momentum is—and what it means for traders, manufacturers, and investors.
🛣️ National Roads: Paving Cambodia’s Trade Arteries
National Road 5 Upgrade (Phnom Penh to Poipet)
Length: 366 km
Completion: Phased since 2022; fully operational in 2025
Partners: Japan International Cooperation Agency (JICA)
Linking Phnom Penh to the Thai border, National Road 5 is now a 4-lane high-capacity corridor, enabling faster trucking between capital hubs and the Poipet Special Economic Zone. This corridor is a game-changer for exports to Thailand and Western Cambodia’s agricultural belt.
National Road 4 Modernization
Route: Phnom Penh to Sihanoukville Port
Status: Ongoing dualization and safety upgrades with World Bank & ADB support
Significance: Primary freight corridor for import-export activity via Sihanoukville Port
Border-to-Factory Connectors
Smaller road investments are quietly transforming mobility:
| Road Segment | Impact Area |
|---|---|
| NR48 (Koh Kong) | Coastal timber & eco-trade access |
| NR6 (Siem Reap to Kampong Thom) | Agri-logistics for cashews & rice |
| NR7 (Kralanh to Laos border) | Future China-Laos-Cambodia corridor |
⚓ Ports of Progress: Maritime & Inland Gateways
Sihanoukville Autonomous Port (SAP)
Role: Cambodia’s only deep-sea port
Upgrades (2023–2026): Container Terminal expansion, digital customs interface, green cold chain initiative
Capacity Goal: 1 million TEUs annually by 2026
SAP is critical for direct exports to China, India, and ASEAN markets, reducing reliance on Vietnamese ports.
Phnom Penh Dry Port & Logistics Hub
Location: Intersection of National Road 4 and the Northern Rail Line
Features: Container depot, bonded warehouse, rail loading zone
Function: Decongests SAP, facilitates inland containerization, bonded storage, and last-mile distribution
By 2025, it’s expected to process 500+ containers/week, connecting SEZs inland with maritime hubs seamlessly.
🏭 Cambodia’s SEZ Hotspots: Where the Action Is
Cambodia currently hosts over 20 operational SEZs, with more in the pipeline. These zones offer tax incentives, streamlined customs, and proximity to infrastructure.
| SEZ Name | Location | Key Exports |
|---|---|---|
| Poipet O’Neang SEZ | Banteay Meanchey | Electronics, automotive parts |
| Manhattan SEZ | Svay Rieng | Garments, footwear |
| Sihanoukville SEZ | Preah Sihanouk | Light manufacturing, packaging |
| Phnom Penh SEZ | Kandal Province | Pharmaceuticals, logistics |
| Kampot SEZ (planned) | Southern Coast | Cement, agro-processing |
The strategic alignment of SEZs along major roads and railways enhances just-in-time manufacturing, export packaging, and customs facilitation.
🚧 Logistics Bottlenecks: What’s Still Holding Trade Back?
While 2025 marks impressive progress, a few chokepoints remain:
Lack of multimodal connectors between SEZs and rail lines
Customs delays at border crossings with Vietnam and Thailand
Limited inland waterway utilization despite Tonle Sap and Mekong proximity
Last-mile delivery inefficiencies in rural zones for agri-traders
Solution Strategies:
Promote container-on-rail incentives from dry ports to SAP
Digitalize customs paperwork to cut clearance times
Expand agro-logistics cold storage networks in Takeo, Kampong Cham, and Pailin
🗺️ Trade Flow Insights: Cambodia in Regional Context
Cambodia’s infrastructure map isn’t just about lines and zones—it’s about strategic regional positioning:
To China: Use NR7 ➝ Laos border ➝ China’s Yunnan Province
To Vietnam: Enhanced flows via Bavet/Moc Bai & Prek Chak crossings
To Thailand: Poipet dry port and NR5 modernization reduce transfer delays
Maritime Route: Sihanoukville ➝ Shenzhen or Guangxi in 4–6 days
This triangulated connectivity supports Cambodia’s ambition to export directly, bypassing legacy dependencies, and becoming a logistics linchpin in Mainland ASEAN.
📌 Final Thoughts: Mapping Cambodia’s Trade Potential
From new expressways to smart ports and Special Economic Zones, Cambodia’s 2025 infrastructure upgrades are a leap forward—positioning the country as more than just a manufacturing base, but as a strategic trade facilitator in the region.
For logistics firms, manufacturers, and investors, the path is clearer than ever. Cambodia isn’t just catching up—it’s setting the pace.
