　　望東(dong)長(chang)(chang)江公(gong)(gong)路(lu)大(da)(da)橋(qiao)是(shi)國家(jia)高速公(gong)(gong)路(lu)網(wang)G35（濟南至廣州高速公(gong)(gong)路(lu)）中(zhong)最(zui)為便捷(jie)的(de)(de)過江通道(dao)，是(shi)安(an)徽省“四縱(zong)八橫”高速公(gong)(gong)路(lu)網(wang)中(zhong)“縱(zong)四”商(shang)丘至景德(de)鎮公(gong)(gong)路(lu)的(de)(de)重要組(zu)成(cheng)部(bu)分。項目(mu)全長(chang)(chang)38.025公(gong)(gong)里，其中(zhong)長(chang)(chang)江大(da)(da)橋(qiao)長(chang)(chang)3.608公(gong)(gong)里，主橋(qiao)為主跨(kua)638米PK鋼混組(zu)合梁斜拉橋(qiao)，分南北兩座主塔，采(cai)用(yong)懸臂鉆石(shi)型橋(qiao)塔結構，均由上、中(zhong)、下塔柱(zhu)和橫梁組(zu)成(cheng)，塔柱(zhu)總高度216米，索長(chang)(chang)315.4米，是(shi)目(mu)前國內外最(zui)大(da)(da)跨(kua)度的(de)(de)組(zu)合梁斜拉橋(qiao)。

　　歷時(shi)近兩年(nian)的(de)(de)望東長(chang)江大(da)橋主(zhu)(zhu)塔施(shi)工(gong)(gong)(gong)，在全體(ti)工(gong)(gong)(gong)程參建人員的(de)(de)努(nu)力下，先后(hou)克(ke)(ke)服了高空、高溫(wen)、臺風(feng)等不利因素，安(an)(an)全、質(zhi)量控制得當，施(shi)工(gong)(gong)(gong)進度、質(zhi)量均達到(dao)預(yu)期目標。此次(ci)大(da)橋南(nan)北主(zhu)(zhu)塔的(de)(de)成功(gong)封頂，意(yi)味著(zhu)大(da)橋已攻克(ke)(ke)技術含量最高、施(shi)工(gong)(gong)(gong)難(nan)度最大(da)、安(an)(an)全風(feng)險(xian)最高的(de)(de)關鍵節(jie)點，標志(zhi)著(zhu)大(da)橋完(wan)成了重(zhong)大(da)節(jie)點工(gong)(gong)(gong)序轉換(huan)，主(zhu)(zhu)體(ti)工(gong)(gong)(gong)程轉入(ru)了斜拉(la)橋主(zhu)(zhu)梁(liang)施(shi)工(gong)(gong)(gong)和斜拉(la)索掛索施(shi)工(gong)(gong)(gong)的(de)(de)新階段，為望東大(da)橋完(wan)成主(zhu)(zhu)跨合龍、實(shi)現全橋貫(guan)通奠定了堅實(shi)基礎。
