国家重点工程威海至乌海线辛庄子至邓王段高速公路地处山东省北部的黄河下游鲁北平原,渤海湾西南岸,黄河三角洲腹地,路线经过的地区为黄河冲积平原,海拔高程一般在1～20米之间,地势向东北倾斜比降一般在1/8000～1/10000之间。由于历史上黄河多次改道和决口泛滥,造成沉积物交错分布,加上海潮内侵、自然侵蚀和人类活动的影响,形成了低岗、
National Key Project Weihai-Wuhai Line Xinzhuangzi-Dengwang Expressway is located in the northern part of Shandong Province in the lower Yellow River, the Lubei Plain, the southwest coast of the Bohai Bay and the hinterland of the Yellow River Delta. The route passes through the Yellow River alluvial plain, 1 to 20 meters, the terrain to the northeast slope than the general decline in 1/8000 ~ 1/10000 between.
