Kien Bridge Cầu Kiền is a road bridge spanning the Cấm River in Haiphong, Vietnam.
Description
editKien Bridge is a Cable-stayed bridge.[1] The length of of the bridge is 1,186 m (3,891 ft), with a its span 200 m (660 ft) long.[1] It is a key link on Vietnam's National Route 10 by spanning the Cấm River in Haiphong, helping travelers more easily navigate through the Red River Delta. [1]
Construction
editBefore the opening of the Kien Bridge, going between the river banks required travel by either boat or ferry.[2] Construction began in 2001 as a Vietnam-Japan joint venture. The building process required a diverse range of methods to address the complicated geology of the riverbed in the area.[2] This included the installation of a nearly 100 m (330 ft) crane tower and using the cantilever method to have crane to mount 110 box girder blocks weighing 14,300 tons.[2] As a cable stayed bridge, construction required the tensioning of 375 tons of prestressed cable to make the 36 pairs. [2] Overall, it was estimated that the building of the Kien bridge required 5,000m³ of reinforced concrete and 6,910 tons of steel. [3]
Operation
editThe bridge was inaugurated on September 28, 2003. The bridge connected Haiphong City of Quang Ninh Province with the Northeast and North Central regions of Vietnam, creating a road between the two communes An Hong and Kien Bai Haiphong. It quickly became a popular route as industrial development in the region led to a regular flow of tractor trailers using the bridge.[4] Its lack of maintenance gradually led to the degradation of the road's surface.[5] In 2014, the news outlet Thanh Nien described the potholes as "A Matrix of Elephant Nests" and reported serious, sometimes fatal, traffic accidents occurring due to road's deterioration.[5] There were further reports of warped railings and damaged expansion joints.[5] In 2021, officials approved extensive repairs of the roads of National Highway 10, including the road between Da Bac Bridge and Kien Bridge.[6]
