Incredible images of the new Hoover Dam Bridge: when finished it will rise 890 feet above the Colorado River; its total length will be 1,900 feet
Spectacular structure: The Hoover Dam Bridge rises from the river banks in the middle stages of the £160million project. This image, which was taken in April this year, shows how the new bridge will replace the old road which crossed the top of the dam

It is one of the planet's newest awe-inspiring superstructures - the Hoover Dam Bridge.
the giant construction project which is on schedule to be completed in
September can be seen in all its glory in a series of stunning
years in planning and five years under construction, the development -
known officially as the 'Mike O'Callaghan-Pat Tillman Memorial Bridge' -
is finally taking shape.
in the shadow of the iconic Hoover Dam, which powers most of states
Nevada and Arizona, the construction is the first concrete-steel
composite arch bridge built in the United States.
With costs estimated to run to £160 million, the bridge is designed to take the pressure off the congested US Highway 93, which connects Las Vegas, Nevada, in the west with Arizona and the Grand Canyon in the east.
bridge is expected to carry 17,000 trucks and cars every day and will
allow the roadway that runs on top of the Hoover Dam to close.
long been the most accessible river crossing between Nevada and
Arizona, the dam is thought to be at risk of a terror strike, with
trucks already banned from crossing.
In November, cars will no longer be able to cross the dam which was built in 1936.
Don't look down: Workers use a crane to construct the top of the bridge's arch during the large-scale project. The picture, taken in August, 2009, shows how engineers anchored the structure in the canyon's sides
Let there be light: Night work on the Hoover Bridge continues unabated thanks to huge lighting towers built in September last year. The bridge is due to be completed later this year
Designed by T.Y Lin International, the bridge will be four lanes wide and is designed to match the style of the dam shadowing it, which holds back artificial Lake Mead.
workers have helped construct the bridge using 2,300 feet long steel
cables held aloft by a 'high line' crane system.
The distinctive arches are made up of 106 concrete and steel arches, each one 24ft-long.
The bridge has been named after Mike O'Callaghan, a former Nevada Governor and Pat Tillman, the American Football player who left the NFL and joined the army after the 9/11 attacks.
Tillman was killed in a friendly fire incident in Afghanistan in 2004.
Documenting the last 18 months on camera has been Santa Fe resident Jamey Stillings, 38.
Patriotic: The new bridge will provide much needed relief for cars and lorries using U.S. Highway 93. The road provides a scenic link between the Grand Canyon, to the east and Las Vegas to the west
'I was driving on a road trip through Nevada across to Arizona when I took in the Hoover Dam as a tourist,' said Jamey, who has been photographing the Bridge since March 2009.
'I came across the construction of the bridge without warning and it captured a piece of my imagination.'
to stay for a night nearby, Jamey set about forming a project to
photograph the bridge as it's put together step-by-step.
'I fell in love with it and wanted to begin a photographic project immediately,' said Jamey.
have been a photographer working in environments such as war zones in
Nicaragua and in advertising and corporate work, but this was a chance
to return to my roots.
'I have made ten trips in total to the bridge. I have spent 26 days and nights at the site with the workers and have taken over 12,000 frames.'
