我通过关于桥梁的“新”施工方法的文章感到令人愉快，例如俄亥俄州的以下一个。

In the article titled “For I-75 Span Replacement, ODOT Plans Ohio’s First Bridge Slide” (as reported in the Toledo Blade and daily ENR News Alert on 6/22), the Ohio Dept. of Transportation is planning to slide in a replacement for the Interstate 75 bridge over U.S. 6 later this year, the first time the method will be used on a state project.

您可能对1915年的工程新闻中附带的文章感兴趣。它在1914年由宾夕法尼亚铁路完成的桥梁幻灯片报告。该桥组成三个双轨通桁跨度，每个跨度长度为240英尺。幻灯片在10分钟，17秒和预定列车之间完成。

Haven’t seen anyone top that!
