The Bai Chay Bridge spans the Cua Luc Strait, which is part of Ha Long Bay. This cable-stayed bridge is not only a symbol of architectural grandeur but also serves as a link between different areas of Ha Long City, the capital of Quang Ninh Province. The city was established in 1993 through the merger of the former provincial capital of Quang Ninh, Hon Gai, with the Bai Chay tourist area.
Built on Highway 18A, this bridge connecting the Hon Gai area and Bai Chay district facilitates comfortable and easy travel for local residents and visiting tourists. The bridge not only showcases a marvel of engineering but also makes a significant contribution to the economic and tourism development of Quang Ninh.
