Summary
China's Ministry of Transport has announced that the "Golden Outer Ring" (黃金大外環) highway project will enter its final construction phase during the 15th Five-Year Plan period (2026-2030). When completed, this 27,000-km super corridor—formed by linking three national highways along China's borders and coastline—will stretch equivalent to two-thirds of Earth's equator .
Key Points
- The "Golden Outer Ring" consists of three national highways: G219 (~10,000 km from Kanas, Xinjiang to Dongxing, Guangxi), G331 (~9,200 km from Dandong, Liaoning to Altay, Xinjiang), and G228 (~7,400 km from Dandong to Dongxing along the coast)
- G331's Jilin section was fully connected in 2023, becoming a popular border tourism route that received over 2 million visitors in the first half of this year alone
- Construction milestones include the Fuding Donggang Bridge on G228's Fujian section achieving south-boundary closure on August 14, with completion expected by year-end
- G331's Dajiucai River Estuary Bridge, the longest suspension bridge in Northeast China, had its main towers topped out on August 21, entering upper-structure construction phase
- Total investment for the project is estimated at 3.7 trillion yuan (approximately 4.073 trillion HKD), with approximately 7,400 km of roads requiring construction or upgrading
Why It Matters
The route connects over 100 land ports and major seaports nationwide, transforming border and coastal road networks from isolated dead-ends into a circular system . For Hong Kong travelers, this creates unprecedented自驾遊 access to diverse landscapes—from snowy plateaus and forests to deserts and coastlines—while also presenting investment opportunities in infrastructure, materials, and logistics sectors along the route .
