从“摆渡船”到5分钟穿黄，济南黄岗路黄河隧道通车首日获市民点赞_我的网站

一 |           　　世界最大直径水下盾构隧道、国内首条穿黄单洞双层盾构隧道——济南黄岗路黄河隧道于8月25日上午正式通车。这条隧道南起蓝翔中路，北接G309互通立交，全长约5755米，单洞双层布置，设计时速60公里。      　　通车后，济南主城区与新旧动能转换起步区之间的跨黄通勤时间从约40分钟压缩至5分钟，将有效缓解现有跨黄通道的交通压力，让市民从“绕行过黄河”变为“直通过黄河”，有力促进济南拥河发展，加快新旧动能转换起步区建设。值得一提的是，济南牌照(鲁A、鲁S)9座及以下小型客车可免费通行该隧道。

二 |     A Chinese research team has completed an updated geologic map of the entire moon featuring a scale of 1:5 million, the Institute of Geology, Chinese Academy of Geological Sciences (IGCAGS), said on Thursday.    Representing a significant scientific iteration from the 2024 version, this map effectively rewrites the moon's geologic history based on the latest research findings. "The lunar geologic history has indeed been rewritten -- more precisely, refined and systematized," said Yang Zhiming, director of the IGCAGS.    Specifically, a primary achievement of this update is the recalibration of the moon's ancient geologic eras. The new map systematically updates the age boundaries of the moon's three ancient geologic periods, namely the Aitkenian, Nectarian and Imbrian periods, drawing on recent advances in international chronology.    Crucially, Chang'e-5 samples confirmed volcanic activity on the moon as recently as 2 billion years ago, extending its geologic lifespan by 1 billion years from the previously accepted 3 billion years. This independent dating data has now become a cornerstone of the global lunar geologic timescale.    Highlighting these spatial discoveries, the new global lunar geologic map is the first comprehensive canvas to bear exclusive findings from the Chang'e-6 mission. "The lunar samples and this map will provide a new starting point for scientific discussions regarding the lunar far side," said Jin Ming, an associate researcher at the IGCAGS.    The map details the age of young mare basalts on the lunar far side obtained from the Chang'e-6 samples, recording the region's volcanic history. Furthermore, it reveals that KREEP rocks, enriched with rare earth elements and other strategic resources, are far more continuous and abundant in the Oceanus Procellarum than previously estimated. This discovery, achieved by eliminating spectral noise, prompts a systemic reevaluation of the moon's early magma ocean crystallization and internal thermal evolution.    Beyond its scientific data, the 2.8-by-1.2-meter map introduces a proprietary cartographic standard. Identifying over 13,500 impact craters and 81 basins, it employs a unique color scheme rooted in geologic logic and traditional Chinese aesthetics, following a "lighter for younger, darker for older" principle.    Furthermore, this standard will also be applied to future geologic mapping of Mars and asteroids, ending reliance on foreign standard systems.    "This goes beyond showcasing technological soft power. This standard will be extended to future planetary geologic mapping, establishing an independent intellectual property framework for China's deep space exploration," Yang said.                    。      　　“我记得20世纪70年代初的时候穿越黄河靠的还是摆渡船，当时还有个铁路大桥，公路基本上没有。如今穿黄已经实现了四桥三隧，非常方便。”一位市民寻访团的市民代表告诉记者。

三 | 据悉，由济南城市建设集团负责建设的“四桥四隧”工程已完成“四桥三隧”建设任务，济南航天大道黄河隧道(Ⅰ期)目前已双线贯通，跨黄通道正加速成网。

四 |      　　另一位市民代表马女士告诉新黄河记者：“我们作为第一辆车剪彩进入隧道后，看到路面非常平整、宽阔，车辆行驶起来非常平稳，也就用了4分多钟就穿越了隧道。记得在我小时候，需要乘坐公交车穿越黄河老桥绕行，如今真是方便多了。对于济南籍的小客车还是免费的，非常好。
