Since construction began in 2005 the Hoover Dam Bypass Bridge has been a project which has kept the world watching. It has had its pitfalls but things seem to be pretty much on schedule.

The latest milestone has been the completion - and joining in the middle - of the main arch. The supporting cables have now been removed and it is freestanding - all that is left is to build the pillars from it on which the road will stand.
