　　1月7日，由湘潭城发集团铁投公司、中交三航局湖南分公司负责投资并建设的杨梅洲大桥，成功克服了特殊天气以及施工难度大等问题，一次性完成河西引桥第二联预应力现浇箱梁大方量　　浇筑，实现主线“第一跨”，标志着杨梅洲大桥建设开启桥梁施工的新阶段。
　　杨梅洲大桥是湘江跨度最大的斜拉桥，湘潭建设的重点项目。临近年关，杨梅洲大桥桩基施工也临近尾声，施工主要作业面转向桥梁施工。杨梅洲大桥引桥第二联由两幅30米长，21米宽的桥箱梁组成，大跨度对箱梁的预应力验算要求更加严格，经过反复验算，通过采用纵向预应力钢束按整联一次性浇筑施工布设，分为顶底板束和腹板束，横梁设置横向预应力钢束，来确保承载能力极限状态强度满足要求。施工人员连续工作30多个小时，将960立方米的箱梁一次性浇筑完成。
