廣州南部地區（侖頭～龍穴島）新龍大橋
質量計劃
一、前言
廣州南部地區快速路位于廣州市南部，貫穿番禺南北，北接廣州環城高速公路南環線，南接龍穴島深水港，是廣州南部地區未來道路主骨架網絡的重要組成部分。
新龍特大橋是廣州南部地區快速路的重點橋梁工程項目，該工程位于珠江三角洲平原區番禺珠江河口段，起點為番禺區新墾鎮，終點為龍穴島西堤岸新港區，是快速路最南端的一座特大橋，先后跨十七涌和龍穴南水道，按城市快速路標準設計。是南沙開發區的標志性工程之一，該橋的建成對廣州南部地區的發展起著至關重要的作用。
為了本項目工程滿足合同需要，確保工程在項目施工期間嚴格按照已制定的具體質量要求，滿足創廣州市樣板工程的目標，特制定新龍大橋工程《質量計劃》。
