2月13日凌晨,深江铁路洪奇沥水道公铁大桥首桩浇筑完成,标志着大桥全面进入桩基施工阶段。
新建深江铁路正线全长约116公里。其中,深江铁路洪奇沥水道公铁合建段主桥长度1.41千米,主跨808米,系世界首创公铁合建超短边跨双塔双索面混凝土—钢箱桁混合组合梁斜拉桥新结构体系,也是全线的关键控制工程。大桥上层为八车道城市快速公路,下层为四线高速铁路。
深江铁路是国家“八纵八横”高铁网沿海通道的重要组成部分。项目建成后,广东省沿海高铁主通道由此全线拉通,进一步打造“轨道上的大湾区”,带动粤东粤西与珠三角的区域协调发展。届时,深圳前海与广州南沙将实现半小时高铁互联互通,深圳与江门可实现1小时内通达,珠江口东西两岸融合互动发展更加密切。
