The construction time of Suojia Bridge on the canal is early, the design standard is low, and there are many heavy vehicles. After long-term overload operation, the bridge deck has been damaged in many places. In order to ensure the traffic, we have also carried out many maintenance work, but we can't solve the problem fundamentally. At present, we have made a plan to close the bridge. Before the implementation of the project, we will make an announcement with the public security traffic police department.
