According to the special meeting of Huangbaihe bridge on Yiba highway recently held by the municipal government, the bridge will become a new landscape in the urban area.

Previously, the municipal government attached great importance to the damage of the bridge (this newspaper has reported), and then invited provincial and municipal experts to identify the bridge. Experts believe that the piers of Huangbaihe bridge are in good condition, but the deck is damaged and needs to be repaired. At present, according to the maintenance plan prepared by relevant departments, there are two options. One is the maintenance scheme with a clear width of 7 meters, and the other is the maintenance scheme with a clear width of 9 meters.

According to the requirements of the municipal government, as Huangbai River Bridge is the main channel connecting sanyudong and other famous tourist areas, we should not only consider the traffic safety of the bridge, but also do a good job in the landscape design of the bridge as far as possible, so as to ensure the completion of the maintenance of Huangbai River Bridge within half a year. In addition, as the water area under the Huangbaihe bridge is a class III waterway, in order to prevent ship collision and ensure the safety of the bridge, the anti-collision design of the bridge piers will also be carried out.
