Inland river freight costs are historically high for a tight supply of barges, increased operating costs, and higher demand moving commodities upbound on the major rivers.

由于驳船数量有限、经营成上升以及各主要的北向运输需求增加，的运费达到了历史最高水平。

With descending of the main pier s foundation slab and integral moving of pier,not only the navigable dimensions meet the demand,but also the influence on upbound ships is very li.

通过下降主墩承台及整体北移桥墩,使通航尺达到要求,且对船舶上行影响极小。
