新华财经上海10月2日电 过江通道"行路难"，又一次成为"黄金周"出行无法绕过的话题。作为长三角北 翼的核心过江通道，也是预测流量最大的过江通道，苏通大桥的拥堵现象具有区域代表性。10月2日， 南通交警的统计数据显示，10月1日苏通大桥实测的实时过江流量为近15.7辆，较预计值高出0.9万辆左 右，也高于去年同期的14.7万辆。 2024年，长三角已建和在建高铁覆盖了区域内所有设区市，宣告"轨道上的长三角"实现新突破；2025年 9月，常泰长江大桥正式通车后，江苏建成的过江通道则已增至20座。交通网络越织越密，为何过江通 道节假日仍难逃"添堵"困境？ 江苏过江流量日均预测值（图片来源："南通交警"公众号） 汽车保有量飙升，致过江通道超设计流量运营 自驾已成为假期出行的绝对主力。交通运输部在9月28日的国务院新闻办发布会上指出，本次中秋国庆 假期，自驾占出行总量的八成左右。新华财经针对"黄金周"自驾过江的需求展开探询，多位受访者表 示，"便捷性"是选择驾车出行的首要考量。 可见，过江通道原有通行能力逐渐难以适配激增的车流，正是出现频繁拥堵的核心原因。 功能性主导地位难替代，亟待平行通道分流 "不少过江通道的'不 ...

9月23日，在位于安徽宿州市的施工现场，随着一段接触网导线精准架设到位，淮宿蚌城际铁路全线首条接触网导线架设任务顺利完成， 标志着淮宿蚌城际铁路正式进入全线接触网架设阶段。 图为淮宿蚌城际铁路全线首条接触网导线架设现场。（中国铁建电气化局供图） 接触网工程是高铁电力牵引供电系统的"生命线"，承担着向动车组输送27.5千伏额定电压的重要任务。据参建单位中国铁建电气化局项目 负责人宋会杰介绍，高铁列车通过车顶的受电弓汲取接触网导线上的电能为列车提供动力。接触网导线架设精度直接决定弓网匹配稳定性与供 电可靠性，对高铁运行安全至关重要。据悉，淮宿蚌城际铁路共需架设接触网导线426.6公里。 淮宿蚌城际铁路北起淮北北站，向南经淮北、宿州、蚌埠三市，接入蚌埠南站，正线长约162公里，设计时速350公里。线路建成通车后， 将成为皖北城市群连接合肥都市圈及沪宁杭等地区的便捷通道，对打造"轨道上的长三角"，促进区域经济协调发展等具有重要意义。（记者樊 曦） 【纠错】 【责任编辑:薛涛】 ...
