原标题：我省最长湖底隧道通车
记者5月15日从郑州市郑东新区管委会获悉，我省最长湖底隧道——龙源十三街隧道正式通车。
该隧道全长3150米，暗埋段长2630米，为双向六车道。隧道南侧起点与如意东路相接，在北三环南侧进入暗埋段，连续下穿北三环隧道、北龙湖、金融岛及其内湖、龙湖内环北路后，在龙湖中环北路南侧出暗埋段，向北与通往金水科教园区的龙源路相接。该隧道正式通车后，可完善郑东新区龙湖地区的交通市政设施，实现龙湖地区尤其是龙湖金融岛南北向的快速通行，并可缩短金水科教园区与郑东新区CBD的交通距离，进一步扩大中原科技城及郑东新区核心区的辐射范围。
按照规划，该隧道是龙湖地区立体综合交通网络系统的组成部分，此立体系统共分五层，集地铁、湖底隧道、水路、地面交通、高架轻轨于一体，是推动中原科技城加快发展的重要交通设施支撑。（李林）
