Ben Thuy Bridge 1 (Шаблон:Lang-vi) is a road bridge in the North Central Coast of Vietnam and is part of the National Route 1

Description

Ben Thuy Bridge 1 (sometimes referred to as just "Ben Thuy Bridge") is a box girder bridge that spans the Cả River connecting Nghe An Province and Ha Tinh Province in the Ben Thuy area. The bridge is Шаблон:Convert long with thirteen spans. [1] The structure includes a prestressed reinforced concrete T beam for a leading span, a steel truss girder for the main spans, two simple beam Шаблон:Convert spans, and three continuous girder spans.[2]

Construction

Before its construction, crossing the Ca river required travel by ferry or by pontoon bridges.[3] For many years, there were only three ferries available, carrying both pedestrians and vehicles from the major arteries of the two provinces, resulting in frequent traffic jams.[3] As part of an effort to improve infrastructure and economic conditions in the region, construction began in 1986 for what would be the first permanent bridge to cross the Ca River.[3] Over 500 staff worked on the project, including many who would relocate and live in quarters on the construction site.[3] In order to build the center of the bridge's span, steel fencing was built to drain the river from the construction site and P300 concrete was poured for the center pillars.[3]

Operation

In 1990, the bridge opened for traffic, making it the then-second longest bridge in Vietnam.[3] From 2009 to 2010, a number of substantial motor accidents began to effect the structural integrity of the bridge. [1] The subsequent unplanned closures for structural testing caused traffic jams reaching the thousands of vehicles, pointing to its key place in the country's transportation infrastructure.[1] For three months of 2014, the Bridge was closed to traffic for its first major repair since its opening.[4]

In 2010, it was announced that Ben Thuy Bridge 2 would be built to reduce the burden for the original bridge.[5]
