滬通(tong)(tong)長(chang)(chang)(chang)江(jiang)大(da)橋(qiao)(qiao)(qiao)位于(yu)江(jiang)陰大(da)橋(qiao)(qiao)(qiao)下游45公(gong)(gong)(gong)里處，南岸為(wei)(wei)(wei)張家港(gang)市(shi)，北岸為(wei)(wei)(wei)南通(tong)(tong)市(shi)，是滬通(tong)(tong)鐵(tie)(tie)路(lu)(lu)、通(tong)(tong)蘇嘉城際鐵(tie)(tie)路(lu)(lu)、錫通(tong)(tong)高(gao)速(su)公(gong)(gong)(gong)路(lu)(lu)共同的過江(jiang)通(tong)(tong)道。全長(chang)(chang)(chang)11072米(mi)，其(qi)中公(gong)(gong)(gong)鐵(tie)(tie)合建橋(qiao)(qiao)(qiao)梁長(chang)(chang)(chang)6993米(mi)，主航道橋(qiao)(qiao)(qiao)為(wei)(wei)(wei)主跨1092米(mi)鋼桁梁雙塔斜拉橋(qiao)(qiao)(qiao)，主塔高(gao)330米(mi)，為(wei)(wei)(wei)同類橋(qiao)(qiao)(qiao)梁世界(jie)最高(gao)。大(da)橋(qiao)(qiao)(qiao)上層為(wei)(wei)(wei)6車道高(gao)速(su)公(gong)(gong)(gong)路(lu)(lu)，設計(ji)時速(su)為(wei)(wei)(wei)100公(gong)(gong)(gong)里；下層為(wei)(wei)(wei)4線(xian)鐵(tie)(tie)路(lu)(lu)，其(qi)中兩(liang)線(xian)滬通(tong)(tong)鐵(tie)(tie)路(lu)(lu)設計(ji)時速(su)為(wei)(wei)(wei)200公(gong)(gong)(gong)里，兩(liang)線(xian)通(tong)(tong)蘇嘉城際鐵(tie)(tie)路(lu)(lu)為(wei)(wei)(wei)客運專線(xian)，設計(ji)時速(su)為(wei)(wei)(wei)250公(gong)(gong)(gong)里。
滬(hu)通長江大(da)橋(qiao)是目前(qian)世(shi)(shi)界上(shang)最大(da)跨度公鐵兩(liang)用(yong)斜拉橋(qiao)，采用(yong)了新(xin)(xin)(xin)(xin)材料(liao)、新(xin)(xin)(xin)(xin)結構、新(xin)(xin)(xin)(xin)設(she)備和新(xin)(xin)(xin)(xin)工藝，代表了世(shi)(shi)界橋(qiao)梁技術的發展方(fang)向(xiang)。大(da)橋(qiao)實現(xian)合龍(long)，后(hou)續將(jiang)進入(ru)鐵軌鋪設(she)、路面澆筑的最后(hou)沖刺階段。
