（来源：荔枝新闻） 转自：荔枝新闻 用"两侧拼宽为主、局部分离为辅"的方式，扩建为双向八车道高速公路，设计速度提升至120公里/小 时。经测算，该路段小客车日均通行能力将由扩建前的2.5万-5.5万辆提升至7万-10万辆，通行能力实现 倍增。 施工期间，长深高速连淮段一度采用单车道通行，限速60公里/小时，部分收费站关闭。如今，苏北这 条大动脉也顺利进入了双向八车道时代。 项目通车后，将有效提升道路通行效率与安全性，完善区域路网体系。同时，将进一步强化连云港港 区、花果山机场及淮安涟水机场的集疏运体系，促进苏北各城市间要素高效流动与产业协同发展，为区 域产业升级、招商引资与民生改善提供强有力的保障与支撑。 连云港至宿迁高速公路徐圩至灌云段是《江苏省高速公路网规划（2017—2035年）》"十五射六纵十 横"中"横三线"的重要组成部分。项目全长40.65公里，途经徐圩新区、海州区和灌云县。全线采用双向 四车道高速公路标准建设，设计速度120公里/小时，共设互通式立交5处、服务区1处。 项目通车后，将大幅优化徐圩港区和花果山国际机场集疏运条件，进一步完善区域路网布局，为沿线城 镇发展注入新动能，同时有力促进产业集 ...
