城市快速路属最高等级城市道路，全程立体交叉、没有红绿灯，可以大幅提升跨区通行效率。从20世纪80年代起，北京便逐步建立起"环路+放射线"的城市 快速路网。去年，北京一口气打通了三条城市快速路：东北方向的京密快速路，从空中跨越"堵点"大山子，为平行的机场高速减负；西北方向的北清快速 路，连通回天地区的居住区与海淀山后的科技园，打通居民的通勤路；东南方向的通马路，无缝衔接北京鲜活农产品流通中心，成为新鲜瓜果肉蛋的快速运 输通道。虹桥飞架，一条条城市快速路，正构建起高效的路网骨架。 京密快速路 本报记者 程功 摄 东北方向 京密快速路 天北路到四环开车只需11分钟 去年7月，历经四年施工建设的京密快速路正式通车。这是继机场高速、京承高速之后，京城东北方向的又一条交通大动脉。 京密快速路南起太阳宫北街，北至京平高速，全长约10.3公里，快速路与原有的京密路走向保持一致，与首都机场高速、地铁首都机场线和15号线并行，贯 穿四元桥立交、五元桥立交、北皋立交及东北环线铁路，实现与四环路、五环路、京平高速等重要通道互连，沿线有主辅路出入口4处，方便望京、崔各庄 地区、孙河地区与中心城区的交通转换。 首发集团副总经理欣立庆介绍 ...

当前，塔山北路快速路穿城段、塔山隧道、蓁山段隧道、山海快速路南段上跨铁路桥、红旗快速路高架 桥、机场路下穿塔山北路节点工程等正加速实施，整体建设态势持续向好。烟台将持续攻坚，力争"一 横两纵"快速路早日建成通车，更好地服务群众便捷出行需求。 栾琪琳介绍，为全面提升城市交通综合承载能力，2021年7月，烟台市全面启动"一横两纵"快速路系统 工程，规划总里程约41.4公里，旨在构建起支撑烟台城市发展的"一横""两纵"快速交通主骨架，形成内 畅外联、高效便捷的现代化交通新格局。 2023年8月，德润、山海快速路两个示范段率先通车，实现了城市快速路"零的突破"。2024年7月，山海 快速路南段完成除涉铁段全部主体工程，形成以烟台南站为核心的高铁枢纽快速疏运通道。2025年，塔 山北路快速路黄金顶隧道西口-红旗路B匝道、岱王山段隧道相继贯通；观海路地道桥、港城西大街互通 立交竣工通车；红旗快速路地面道路分段开放，有效缓解了区域交通压力。目前，已建成快速路17公 里，实现通车12.3公里，市区交通通行条件明显改善。 齐鲁晚报·齐鲁壹点 于洋 12月18日，烟台市人民政府新闻办公室举行"回望十四五 奋楫启新程"主题系列烟台 ...
