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 ...
