Amazing images of human creativity to challenge the impossible: the Hoover Dam Bridge in America again

Amazing images of human creativity to challenge the impossible: the Hoover Dam Bridge in America again
Imagine with me the following: terrain very rugged between two mountains, separated by a steep valley width 579 meters at an altitude of 271 meters in the air above the Colorado River, and required the construction of a bridge linking both sides of the valley on the rise!!
Seems like an impossible idea, but the creativity of another opinion, but let's talk:
What you see in this picture is one of the signs of human creativity does not stop at any obstacle or difficulty, a bridge is being built now in the United States within 48 kilometers southeast of the city of Las Vegas and is supposed to be completed in September.
The motorway usual in this region is going over the Hoover Dam, which you see in the background, but with the growing traffic and the number of vehicles that use this route is no longer the narrow road over the bridge enough for the possibility of all this traffic, was the solution is to build this bridge as part of the project giant would cost $ 250 million for the work corridor starts from Conte in Nevada County and ends at county Mohav in Arizona.
This magnificent bridge took 12 years of planning and 5 years of implementation, with the participation of 3,000 workers took turns working day and night without stopping.
Will pass on the bridge when his 17,000 cars and trucks a day from Highway 93-goers in the United States, which is the road that serves the Las Vegas and Nevada to the west, Arizona and the Grand Canyon to the east.
Are working on this project for 24 hours thanks to the giant searchlights turned this evening to day to place workers can continue their work without interruption!
I wonder how worker can hung on the rise amid these majestic scenes for doing his job to the fullest and with great accuracy!
Despite the magnificence of the project planning and execution except that his name little Sasdmkm, Vdona all distinctive names that can be selected for a project of this beauty decided responsible parties named as the "Bridge Mike O'Callaghan - Pat Tillman Memorial"!! (Did not possible to make it more difficult?!!!)
What lends a distinctive character on this bridge is the dam, which overlooks it, spoiled Hoover was one of the finest engineering projects in the last century, where construction began in 1931 and ended in 1963 with 3.3 million cubic meters of cement! To imagine the size of this quantitative Imagine it enough to paving a road from Cairo to Riyadh 10 meters wide!!
So we see in these scenes meeting different creativity centuries: the Hoover Dam in the twentieth century and bridge .......... In the twenty-first century (I find it difficult to remember his name complex :)!)
These exquisite images of the project during its construction: (mostly dating back to last April)
Finally, I leave you with this wonderful background for your desktop:
