As this immense project nears its completion, take a look at some wonderful photos taken both onsite, around, above and below the Hoover Dam Bypass Bridge. It cannot be said that the golden age of engineering is over when we can still produce projects like this.
It was a few months ago that Scienceray took a preliminary look at the momentous construction project going on near the Hoover Dam – you can see it here. Then we saw how the project began in 2005 and we left it in June of 2009. At that point the arch was more than fifty percent complete and it was hoped that the two sides would meet in the fall. That is in the here and now, so let's take a look at how the project has progressed since then. Have the hopes of the bridge builders come to fruition?
All attention since June has been focused on the arch that will underpin the road that will connect the States of Arizona and Nevada. Certainly, it seems to be painstaking work and the work literally seems to inch towards completion. Not to worry, though. The folks of the two neighboring States are patient people – after all the Dam itself is close to celebrating its seventy fifth birthday. Those who remember its grand opening back in the Great Depression are now octogenarians. Still, the near completion of the arch is cause enough to fly the flags, even though there is a painstaking six feet still to go. Look at this great shot from the completion day in August, however.
If you look to the right of the flags – about ten meters or so, you will see a tiny figure with a safety hat and orange coat. That's one of the construction workers and gives an idea of the sheer scale of the project. There is no doubt that those working on the project must not be afflicted by bouts of vertigo – however occasional. Would you want to be up that high? Just to put it in to context, it is over two hundred and fifty meters down from this height. As Shaggy might say, yikes.
