Cần Thơ Bridge is a cable-stayed bridge over the Hậu (Bassac) River, the largest distributary of the Mekong River, in the city of Cần Thơ in southern Vietnam. The bridge is 2.75 kilometres long (1.68 miles). It has a 6-lane carriageway measuring 23 metres (76 feet) in width, with 4 lanes for traffic and two pedestrian lanes. It has a clearance of 39 metres (128 feet), which allows large ships to pass underneath it.[1] The bridge was inaugurated on April 24, 2010.[2]

The bridge is currently the longest main span cable-stayed bridge in Southeast Asia. The cost of construction is estimated to be 4.842 trillion Vietnamese đồng (approximately US$342.6 million), making it the most expensive bridge in Vietnam.[1]

Construction[edit]

Prime Minister Phan Văn Khải launched construction of the bridge on September 25, 2004, which was scheduled to be completed in late 2008. The collapse of the partially built bridge in 2007 delayed its opening. The bridge is one of seventeen bridges planned to integrate the Mekong Delta into the road network of Vietnam by 2020. The bridge replaced the network of ferries on the National Route 1A linking Vĩnh Long Province on the east shore with Cần Thơ city on the westbank.[1]

The construction of the bridge was supervised by the consultant group Nippon Koei-Chodai and contracted to several Japanese contractors: Taisei Corporation, Kajima Construction and Nippon Steel. Capital for the project was funded by the Japan International Cooperation Agency with official development assistance loan from the Japan Bank of International Cooperation and the Vietnamese government.[1] Cần Thơ Bridge is insured by the Petrolimex Joint Stock Insurance Company and PetroVietnam Insurance Company for 3.2 trillion Vietnamese đồng (200 million U.S. dollars).[3]

The construction of the Cần Thơ Bridge was subdivided into three contracts, with one contractor handling the first approach bridge, the second building the main bridge, and the third constructing the southern approach road into Cần Thơ.[4]

Collapse[edit]

Pieces of Cần Thơ Bridge remaining after its collapse on October 4, 2007, ten days after the accident.

The partially built Cần Thơ Bridge collapsed during construction. The accident occurred at 8 a.m. local time (GMT+7) on the morning of September 26, 2007, when a 90-meter section of an approach ramp, rising more than 30 meters above the ground, collapsed.[5] The collapsed section was above a small island located on the Vĩnh Long side of the bridge.[6] There were 250 engineers and workers working on and under the span at the time.[7][8] As of September 27, the number of reported casualties varies, with one source saying 52 people died and 140 were injured.[9] While other sources show that the death toll has reached 59,[10] still others report the number of casualties have reached 64.[11] According to Dr. Trần Chủng, head of the national construction QA/QC authority under the Ministry of Construction, this is the most catastrophic disaster in the history of Vietnam's construction industry.[12]

Rescue efforts[edit]

Immediately following the accident, many workers at the site joined the rescue forces to take the injured out of the debris.[13] Local people, students, and cadres also joined the rescue teams. In addition, Chợ Rẫy Hospital in Hồ Chí Minh City sent two professional rescue teams to the site.[14] All the combined rescue efforts were put under the leadership of Hoàng Trung Hải, Vice Premier of the Government and forces from Ministries of National Defence.

Rescue efforts received international support. The American Chamber of Commerce in Vietnam sent its resources located in Ho Chi Minh City, Singapore and Bangkok to Cần Thơ. The International SOS Alarm Centre and Clinic in Ho Chi Minh City sent a first response team of three doctors, a nurse, an interpreter and operations manager.[15] Rescue efforts were carried out with cranes rather than by direct rescue personnel because of the risk of collapse of the remaining part of the bridge.[16]

Aftermath[edit]

In response to the collapse, in July 2009 the Vietnamese government punitively banned the Taisei and Kajima Construction companies from operating in Vietnam for one year, blaming the two Japanese companies for failing to secure the bridge support.[17]

Opening[edit]

The largest bridge in the region, was completed on April 12 and opened for traffic on April 24, 2010.
