Recently, Jiangbei highway maintenance authority inspected and found that partial expansion joints of Phase II connecting line, Xiao-Yong Highway and Railway Overpass were damaged. Some expansion joints were found with cracked toothed plates and loose studs due to long bridge operation time and large traffic flow, leaving safety hazards to passing vehicles. In order to ensure the safety of bridge operation, Jiangbei highway maintenance authority mobilized available resources to make cold aggregate emergency repair on some damaged expansion joints and ensure the safe passing of vehicles.

Sticking to the road traffic service concept of strengthening road safety work, improving the safety level of traffic safety on the bridge, and reducing the occurrence of minor and major traffic accidents, considering the actual conditions of the bridge, Jiangbei highway maintenance authority conducted a thorough survey of traffic flow, collected specific data, laid down traffic evacuation scheme, reported on damage repair and make other preparatory works. According to initial estimation, it was required to fill epoxy resin and reinforce 4,608 bolts; removed 17 damaged concretes; replaced 360 damaged high-strength bolts; and removed 45 m comb-type expansion joints.

It is expected that the bridge will be repaired by late April, during which Jiangbei highway authority will implement closed construction of the right lane during staggered peak.
