EHang and CSCEC Sixth Engineering Bureau Begin Work on Hainan Low-Altitude Corridor
EHang is partnering with China Construction Sixth Engineering Bureau to develop low-altitude aviation infrastructure in China, with a cross-sea corridor project in Hainan becoming the first project under the new cooperation framework.
The companies signed a strategic cooperation framework agreement focused on infrastructure development and planning for low-altitude flight operations. CSCEC Sixth Engineering Bureau will contribute its construction and infrastructure capabilities, while EHang will provide eVTOL aircraft, technical expertise and operational support.

Construction has already begun on the Cross-Sea Low-Altitude Corridor Project in Lingao, Hainan. The project is being developed around Maniao General Aviation Airport and will include multiple operational sites and vertiports along the coastline.
The companies plan to establish point-to-point passenger eVTOL routes and cross-sea shuttle services linking Hainan with Guangdong. The first major flight station, WingHub South Sea, is being developed with an operations and exhibition centre, vertiports designed for EHang’s pilotless aircraft and testing areas.

The project builds on EHang’s previous testing of cross-sea operations. In December 2025, its EH216‑S aircraft completed a 22-kilometre flight across the Qiongzhou Strait between Haikou in Hainan and Xuwen Port in Guangdong in 18 minutes.
Initial applications are expected to include aerial sightseeing, low-altitude logistics, training and testing, with cross-sea passenger transport planned as a later phase.
The development also aligns with Hainan’s transport planning for the next five-year period, which calls for island-wide and cross-sea low-altitude routes, upgrades to general aviation airports and additional vertical take-off and landing infrastructure.
