在20世纪80年代之前,我国还没有一座真正意义上的现代化大跨径悬索桥和斜拉桥。进入90年代以后,伴随着大规模公路建设的展开,我国桥梁建设得到极大发展,在长江、黄河等大江大河和沿海海域,建成了一大批有代表性的世界级桥梁。目前,在187万km的公路上,有各类桥梁32万多座、1337. Before the 1980s, our country did not have a truly modern long-span suspension bridge and cable-stayed bridge. Since the 1990s, with the development of large-scale highway construction, bridge construction in our country has been greatly developed. A large number of representative world-class bridges have been built in the great rivers and coastal areas such as the Yangtze River and the Yellow River. At present, there are more than 320,000 bridges of all kinds at 1.37 million km.
