广州南部地区（仑头～龙穴岛）新龙大桥
质量计划
一、前言
广州南部地区快速路位于广州市南部，贯穿番禺南北，北接广州环城高速公路南环线，南接龙穴岛深水港，是广州南部地区未来道路主骨架网络的重要组成部分。
新龙特大桥是广州南部地区快速路的重点桥梁工程项目，该工程位于珠江三角洲平原区番禺珠江河口段，起点为番禺区新垦镇，终点为龙穴岛西堤岸新港区，是快速路最南端的一座特大桥，先后跨十七涌和龙穴南水道，按城市快速路标准设计。是南沙开发区的标志性工程之一，该桥的建成对广州南部地区的发展起着至关重要的作用。
为了本项目工程满足合同需要，确保工程在项目施工期间严格按照已制定的具体质量要求，满足创广州市样板工程的目标，特制定新龙大桥工程《质量计划》。
