京密路二期作为北京东北部重要交通干线，规划等级为高速公路，南起京平高速，北至六环路，全长15公里，其中新国展段（京平高速— 安华街）全长约5.4公里。京密路采用"分段建设、分段开通"模式，践行"建成一段、通车一段、受益一段"的思路，优先保障新国展等核心 功能区交通需求，为周边居民提供高质量通行条件。 此前，新国展段辅路已于今年5月15日通车，京平高速（机场南线）至天北路主路约3.7公里已于10月25日通车。此次通车的天北路至安华 街段主路长1.7公里，同时将新建辅路向北延伸0.5公里至安宁大街，避免高速出口的车流造成交通拥堵。 首发建设公司京密路项目管理处副总经理张义远告诉记者，京密高速由于邻近地铁15号线，施工场地狭小，大吨位梁体的吊装难度大。为 此各方对施工计划开展多轮优化，实现施工工期有效压缩。 京密高速新国展段通车后，这一路段由原双向4车道升级为主路双向6车道及辅路双向6车道，通行能力大幅提升。从新国展出发，最快8分 钟内可进入五环，11分钟可达四环，将显著优化新国展展会期间人流、物流集散效率，缓解周边区域交通压力。 同时，京密高速充分挖潜桥下空间，新增300余个停车位。京密高速天北路至安华街段主路通 ...
