Location

The bridge is one of a handful of "next generation" bridges worldwide,[3] and includes cable dampers that use magnetorheological fluid which have the capability to change viscosity in response to an electromagnetic field. The bridge includes four lanes of traffic—two lanes in each direction.

Description

The Dongting Lake Bridge is connected to Dongting Avenue, China National Highway 107 and Jingzhu Expressway in the east, and the Provincial Highway Route 1804 of Hunan in the west.
