　　11月13日，重庆江津几江长江大桥南锚碇下沉突破1米。

　　锚碇主要是用于将桥面荷载通过跨过主塔的主缆均匀扩散到锚体混凝土中，然后再传到地基的结构物。锚碇对于保障大桥承重安全具有重要的意义。南锚碇为重力式锚碇，沉井基础，锚碇混凝土方量约6.5万方，南锚碇沉井长58.3m，宽45.8m，高23.5m，是重庆地区最大规模沉井。南锚碇分两次下沉，本次为首次下沉，计划下沉10m，预计12月初就可完成首次下沉10米的施工任务。

　　几江大桥全长1738米，为主跨600米的悬索桥，主梁结构采用钢箱梁。大桥设计为双向六车道，设计行车速度为每小时50公里。大桥由中国建筑第六工程局有限公司承建，南起江津区几江街道东门口，跨越长江后北至德感浒溪口，将经过滨江新城滨江休闲风貌带和CBD核心风貌区，直接与在建的南北大道相接。大桥计划将在2016年11月通车。
