8月11日，随着最后一联桥面混凝土浇筑完成，由中铁十四局承建的曲港高速子牙新河特大桥右幅桥面铺装完成，全长3.13公里的子牙新河特大桥贯通。
子牙新河特大桥贯通。曲港高速公路（肃宁互通至京台高速段）工程起自河北沧州市肃宁县，止于沧州市青县，路线全长约96.46公里，设计时速120公里，双向四车道标准设计。由中铁十四局承建标段全长7.17公里，其中子牙新河特大桥为全线控制性关键节点工程。
该特大桥左幅第六联钢箱梁顶推施工是全线施工难度最大、安全防控系数最高的控制性工序。钢箱梁跨70米宽子牙新河，总重量共750吨，相当于150头亚洲象的重量。在顶推过程中，技术人员采用高精度全站仪实时控制顶推线型，并在全桥设置12个步履式千斤顶，以每小时2米的速度向前推进，历时9天完成既定任务。
