混凝土和预应力体系的迅速发展，促使预应力连续梁向双线大跨长联快速发展。1980年修建了跨度为40m简支梁九江引侨和96m跨红水河斜拉桥；1982年建造了82m跨预应力箱型变截面烛漳河斜腿刚构桥；1986年建成了铁路单线茅岭江桥，3跨连续梁，桥长176m，最大跨度80m，悬臂浇筑法施工
The rapid development of concrete and prestressed systems has led to the rapid development of prestressed continuous beams to two-lane long-span links. In 1980 built a span of 40m simply supported beam Jiujiang cited overseas Chinese and 96m across the Hongshui River cable-stayed bridge; in 1982 built 82m prestressed box-shaped cross-section of the Kan Zhang River inclined leg rigid frame bridge; built in 1986 the railway line Maoling River Bridge, 3-span continuous beam, the bridge length 176m, the maximum span of 80m, cantilever pouring construction
