Linking Wales with England the one mile long bridge reaches a height of 445 feet at its peak. This video follows a maintenance crew as they walk up and perform their tasks. What's really interesting about this particular video is the use of a 360-degree camera setup. Using your mouse or the navigation button at the top left, the viewer can pan and look in any direction, very interesting.
Here's another video of the project, sponsored by Scruffs, a manufacturer of workclothes.
