A little while ago, Webphemera featured the amazing construction project that is the Hoover Dam Bypass Bridge.  Since then considerable work has been added to the structure and it is nearer to completion by quite a way.

This picture of the Hoover Bypass Bridge was taken from Lake Mohave by boat in September 2009.  You can clearly see how the supporting cable system has now been removed and the arch is now free standing.  This marvelous image captures the sheer scale and grandeur of the project and proves that sometimes, when it comes to photography, looking up is just as effective as looking down.
