WOW!
this is magnificent! a marvel!
the mere sight of it is making my stomach churn and my palms sweat.
i would need to be sedated and placed in a body bag to cross this bridge.
my pathological and irrational sheer terror of suspension bridges would reduce me to an incoherent quivering blob of jelly!

It is one of the planet's newest awe-inspiring superstructures - the Hoover Dam Bridge.
Twelve 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.
Rising 890 ft above the Colorado River, when finished, its total length will be 1,900 ft, with its longest supported span running to 1080 ft.
Built 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 and is expected to carry 17,000 trucks and cars daily.
It will also allow the roadway that runs on top of the Hoover Dam to close.
Having 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.
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.
Around 3,000 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 is named after Mike O'Callaghan, a former Nevada Governor and Pat Tillman a former All Star American Football player who left his lucrative career and enlisted in the army after 9/11.
He was killed in a friendly fire incident in Afghanistan.
