The Wuhu Bridge over the Yangtze River, a stayed-cable bridge for both highway and railway, is the first and largest of its kind designed independently by Chinese engineers. The Bridge, a key State-level project in the Ninth Five-Year Plan period, was constructed with joint investment by the Ministry of Railway and the Provincial Government of Anhui, and was put into operation in September 2000, after three-and-half years of construction. The bridge has a 10.624 km-long railway part and a 6.078 km-long highway part, with a main span of 312 meters. With a lot of advanced technologies adopted in the design work, this original bridge is a symbolic project of China’s dual-purpose bridge construction in the 20th Century. Completing the railway and highway networks of eastern China, it bore great importance to the expansion of cargo and passenger transportations across the Yangtze River as well as to the economic development of the entire eastern China, especially Anhui Province.

芜湖长江大桥是国家“九五”期间重点交通项目，工程规模居中国长江大桥之首。大桥采用低塔斜拉桥桥型，主跨312米，是中国迄今为止公、铁两用桥跨度最大的桥梁。大桥工程采用了10多项新技术、新结构、新材料、新工艺，大大提高了中国公、铁两用桥梁设计、制造、安装水平，有14项刷新了全国建桥记录，荣获2001年度中国建筑工程最高荣誉鲁班奖。

芜湖长江大桥，全长1002096米，全桥混凝土总量55万吨，结构用钢11万吨，其工程总量及规模均超过了武汉和南京两座公路铁路两用桥的总和，该桥的科技含量、工程规模和建造质量，居国际一流，国内领先。

刷新中国建桥记录的14项成果中有：大桥采用大跨度连续钢桁梁斜拉桥式，首开中国公铁两用斜拉桥之先河，主跨312米，居国内公铁两用桥之最，建桥中采用低塔斜拉公铁桥，也是世界上首创;该桥为满足高速铁路运输，其荷载设计为中国公铁桥最大，铁路桥与公路桥荷载比为6：1，创国内公铁两用桥荷载比差之最;正桥钢梁首次采用中国最新研制的低碳中强钢–14锰铌钢，其屈服强度高于日本、德国同类桥梁，新钢种的开发利用，完善了中国桥梁钢系列;该桥水上基础施工中首次采用3米大孔径钻孔桩，成功攻克深水、动水、厚沙层钻孔难关，其孔径桩深创中国之最。

芜湖长江大桥建设期仅42个月，在中国铁路大型桥梁建设中创出月成桥251米的速度;该桥已完工的上下部工程，经铁道部、交通部专家检测验评，合格率为100%，分项工程优良率100%，综合质量评审超过了国优标准。
