Our bridges have been in the spotlight this month with a national campaign to reduce the number of bridge strikes.
There aremore than 2,000 strikes in Britain each year，花费数百万磅的损坏和数千小时的火车延误。
维护和开发我们的30,000个桥梁，隧道和高架桥是一个巨大的任务。许多这些结构日期来自维多利亚时代的时代，意味着现代化是我们的重要组成部分Railway Upgrade Plan.
我们正在做什么
改进包括A.£7m rolling programme of investment in Dumbarton’s railway bridges在苏格兰的西邓巴德郡今年。该项目包括11个结构，基于每个桥梁或隧道的条件和个人要求。这可包括排水工作，甲板更换，钢加固和绘画。
It’s part of a broader maintenance programme that will extend the lifespan of our lifespan and keep the road and rail network safe and reliable. Work is scheduled for completion by 2019.
在柴郡，我们正在修复和恢复润湿的高架桥作为大型北铁路项目的一部分，因为桥梁接近它的150thbirthday in October.
Network Rail’s Team Orange have been strengthening, waterproofing and refurbishing the bridge’s timber, steel and brick structures since October last year. The essential work will help make the busy railway bridge safer and more reliable.
Meanwhile, our completed projects include theOrdsall Chord railway bridge– the world’s first asymmetrical rail bridge. Open since November, it links Manchester’s Victoria, Oxford Road and Piccadilly stations for the first time. It also enables direct services to Manchester Airport from the North.

Innovations
Reconstructing bridges to fit overhead wires is a costly part ofelectrifying the railway, so in 2014 we teamed up with Rail Safety Standards Board (RSSB) and the Department for Transport to find an alternative, with the help of a competition.
收到资金的项目之一是大arch，一个innovative bridge-jacking techniquefrom Freyssinet and Bill Harvey Associates that can lift masonry arch bridges, preventing the need for demolition and reconstruction.
