The total length of the whole bridge is 752 meters, in which the main bridge is a prestressed concrete cable-stayed bridge with twin towers and double cable planes, with a total length of 452 meters, and the approach bridge is a simply supported T-beam bridge with a span of 30 meters. Due to the long opening time and large traffic flow, the bridge has many diseases at present. The whole overhaul project is divided into two phases, with a total investment of120,000 yuan.
