The Hong Kong–Shenzhen Western Corridor, colloquially known in Shenzhen as Shenzhen Bay Bridge, is a 5.5-kilometre (3.4 mi), dual three-lane carriageway in Hong Kong. It connects Ngau Hom Shek (traditional Chinese: 鰲磡石; simplified Chinese: 鳌磡石), Hong Kong to an area leased by Hong Kong at Dongjiaotou, which is geographically located in Nanshan, Shenzhen, mainland China. It connects Hong Kong with the border crossing facilities on its border with mainland China, the Shenzhen Bay Control Point.
