瀘定城南大橋東北端緊靠瀘定客運(yùn)中心，接瀘定成武路；西南端正對(duì)縣人民醫(yī)院，接豐碑街。由于該橋已成危橋，為了確保兩岸人員及車輛通行，擬在原址修建新橋。新橋結(jié)構(gòu)為：主孔 L=3 預(yù)應(yīng)力砼簡(jiǎn)支梁橋，主孔墩、臺(tái)均采用鉆孔灌注樁基礎(chǔ)。主要設(shè)計(jì)參數(shù)如下：（1）橋梁下部結(jié)構(gòu)橋梁下部從左岸向右岸依次設(shè)置 1～4橋墩。其中 1橋墩下布置單排 2 個(gè)直徑 、深 46m 圓形樁；3橋墩下布置雙排共 4 個(gè)直徑 、深 45 和50m 圓形樁，樁頂設(shè)置長(zhǎng) 寬 高 承臺(tái)，承臺(tái)上部布置單排 2 個(gè)直徑 、高 和 10m 圓形墩；4橋墩下同樣布置單排 2 個(gè)直徑 、深35m 圓形樁。（2）橋梁上部結(jié)構(gòu)主橋上部構(gòu)造為 3 跨 預(yù)應(yīng)力簡(jiǎn)支 T 梁，引橋上部結(jié)構(gòu)為 1現(xiàn)澆 T 梁；橋面寬度：（行車道）+22m（人行道）=。全橋主要工程量樁基鉆孔 m，承臺(tái)砼澆筑 m179。，橋墩砼澆筑 m179。；T 梁預(yù)制m179。，鋼筋制安 t；
