沿海公路秦皇岛至乐亭段高速公路跨京秦铁路、205国道的一座分离式立交原设计跨径为(4×35+4×35+5×35+44+60+44+9×35)米,其中35米跨径部分为预应力小箱梁。沿海高速主线上跨205国道,斜交34.1度,205国道现状宽度为18米,规划为一级路。原方案考虑由于斜交角度小,且需考虑205国道按一级路预留,将205国道改线,在原方案的第四、五孔穿过。由于种种原
The original design span of a separate interchange at Qinhuangdao-Laoting Expressway across Beijing-Qinhuangdao Railway and 205 National Highway along the highway is (4 × 35 + 4 × 35 + 5 × 35 + 44 + 60 + 44 + 9 × 35) meters , Of which 35 meters span part prestressed box girder. Coastal high-speed main line across 205 National Road, Oblique 34.1 degrees, 205 State Road, the current width of 18 meters, the planning for a road.
