一桥飞架南北，天堑变通途。党的十八大以来，一座座技术先进、姿态各异的桥梁建成通车，跨越江河湖海，联通深沟峡谷，使交通节点的连接更加紧密，极大地方便了周边居民的出行生活，为区域经济社会发展铺通了坦途，彰显了我国综合国力和科技进步。
一桥飞架南北，天堑变通途。党的十八大以来，一座座技术先进、姿态各异的桥梁建成通车，跨越江河湖海，联通深沟峡谷，使交通节点的连接更加紧密，极大地方便了周边居民的出行生活，为区域经济社会发展铺通了坦途，彰显了我国综合国力和科技进步。
全球大跨度桥梁，我国占比超50%——“最长、最高、最大”不断被刷新。
7月初，随着世界最长的海底隧道——港珠澳大桥海底隧道贯通，这座中国建设史上里程最长、投资最多、施工难度最大的跨海桥梁主体工程终于全线贯通。预计到今年底，它将建成通车，届时将成为世界上最长的跨海大桥。
集桥、岛、隧道于一体，全长55公里——作为连接香港、珠海、澳门的超大型跨海通道，港珠澳大桥被誉为交通工程的“珠穆朗玛峰”，被外媒称为“新世界七大奇迹”之一。
视线转向内陆，成就同样显著。北盘江大桥，桥面距谷底达到了565米，相当于200层楼高，是世界第一高桥；四川干海子特大桥，世界第一座全钢管混凝土桁架梁桥，最高钢管格构桥墩达117米；鹦鹉洲长江大桥，世界跨度最大的三塔四跨悬索桥；湘西矮寨特大悬索桥，创4项世界第一……近5年来，全球超过一半的大跨度桥梁都出现在中国，“最长、最高、最大、最快”这样的纪录，不断被写进世界桥梁史，让“中国桥”成为展示中国形象的新品牌。
交通运输部向记者提供了一组令人自豪的数字：目前，世界上已建成的跨度超400米的斜拉桥、悬索桥分别有114座、109座，我国就分别拥有59座、34座；全球在建及拟建的主跨400米以上的斜拉桥、悬索桥分别为49座、37座，我国就分别占据了39座、29座。
放眼未来，世界跨度最大的公路铁路两用大桥——沪通长江大桥，世界上跨径最大的钢箱梁悬索桥——虎门二桥等也将于2019年通车。
世界最高十座大桥，我国拥有8座——不断突破世界性技术难题
“纵观世界桥梁建设史，上世纪70年代以前要看欧美，90年代看日本，而到了21世纪，则要看中国。”在世界桥梁建筑领域，这已是大家公认的观点。
2013年7月，嘉绍大桥正式建成通车。这座大桥一举攻克了多塔斜拉桥结构体系、刚性铰新型装置、钢箱梁检查设备关键技术难题，项目成果获得了2016年国际桥梁大会古斯塔夫·林德撒尔奖、2016年国际道路联合会全球道路设计成就奖，在世界范围内得到了广泛认可。5年来，这样突破世界性技术难题的中国桥梁还有很多。
2013年建成的泰州长江公路大桥，在世界上首次实现了多塔连跨悬索桥的千米级突破，为建设跨越宽阔江海水域的桥梁提供了新的方案。
2016年，马鞍山长江大桥获得第三十三届国际桥梁大会最高奖——乔治·理查德森奖，此前，武汉天兴洲长江大桥、南京大胜关长江大桥等多座桥梁先后斩获大奖。
国际桥梁与结构工程协会副主席、同济大学教授葛耀君表示，我国正从桥梁建设大国走向桥梁建设强国，未来5到10年中，我国桥梁技术和桥梁建造水平还将有更新更大的突破。
公路桥梁，我国共有80.5万座——为区域发展打通瓶颈
2016年12月29日上午，随着一辆辆汽车驶上桥面，北盘江大桥正式通车，这也使得杭瑞高速贵州段实现了全面贯通。至此，云贵两省又增加一条高速通道，云南宣威到贵州六盘水的车程由过去4小时缩短至1小时，黔川滇三省交界区域也得以快速融入全国高速公路网，从而步入发展快车道。
跨越江河湖海，联通深沟峡谷。5年来，一座座桥梁的建成，使一个个交通节点的连接更加紧密，也为不少地区的经济社会发展打通了瓶颈、铺平了坦途。
随着自身实力的增强，中国桥梁建设企业也在近年来更加积极地走出去，到世界舞台一展身手。2014年底，由中国交建承建的泽蒙—博尔察大桥建成通车，结束了近70年来贝尔格莱德市多瑙河上仅有一座大桥的历史。这座中国在欧洲修建的第一座大桥，被当地官员形容为“塞尔维亚近几十年来最好的基础设施项目”，更被当地百姓亲切地称作“中国桥”。马来西亚槟城二桥、巴拿马运河三桥、新奥克兰海湾桥……放眼五洲四海，近年来中国建设者主持或参加建设了一个个国际知名桥梁工程，赢得了全球同行的广泛赞誉。
