Cầu Tân Vũ – Lạch Huyện, Sea-crossing bridge in Haiphong, Vietnam.
The Tan Vu - Lach Huyen Bridge is a sea crossing in Haiphong, Vietnam, that links the mainland with Cat Hai Island. The structure counts four traffic lanes and stretches over roughly 5.4 kilometers (3.4 miles) of open water.
Construction began in February 2014 under the supervision of the Vietnamese Ministry of Transport. The project was completed in September 2017 and has since contributed to regional connectivity.
The name combines two geographic points and marks the direct route between mainland and the island world off the coast. Today the structure connects work routes with travel routes and opens a fast path to the limestone landscapes of Ha Long Bay.
The crossing reduces travel time between the mainland and Cat Hai Island from over two hours to less than a quarter hour. The direct link eliminates the ferry route and the road remains open in most weather conditions.
The structure ranks as the longest sea crossing in Southeast Asia and forms part of a highway system that extends almost 16 kilometers (10 miles) to Lach Huyen Port. The entire layout supports both the port economy and island traffic directly.
