The construction of the navigation channel of the Xijiang Bridge in Wuzhou
was officially launched in early September. Because the Xijiang Bridge that
cannot meet the two-way navigation, the construction adopts the method
of "half construction and half navigation". It will have a major impact on ships
passing through the lower approach channel of the Changzhou ship lock to
the waters of the Guijiang Estuary.For this waterway construction,it need
the dredgers(with silt curtains)for waterway dredging carefully.
