Hoover Dam Bypass
. .

 

 

A little construction project in Las Vegas ' backyard.

 

 

 

THE WIDER VIEW: Taking shape, the new bridge at the Hoover Dam

 

Creeping closer inch by inch, 900 feet above the mighty Colorado River , the

two sides of a $160 million bridge at the Hoover Dam slowly take shape.

The bridge will carry a new section of US Route 93 past the bottleneck of

the old road which can be seen twisting and winding around and across the

dam itself.

 

When complete, it will provide a new link between the states of Nevada and

Arizona . In an incredible feat of engineering, the road will be supported

on the two massive concrete arches which jut out of the rock face.

 

The arches are made up of 53 individual sections each 24 feet long which

have been cast on-site and are being lifted into place using an improvised

high-wire crane strung between temporary steel pylons.

 

 

The arches will eventually measure more than 1,000 feet across. At the

moment, the structure looks like a traditional suspension bridge. But once

the arches are complete, the suspending cables on each side will be removed.

Extra vertical columns will then be installed on the arches to carry the

road.

The bridge has become known as the Hoover Dam bypass, although it is

officially called the Mike O'Callaghan-Pat Tillman Memorial Bridge, after a

former governor of Nevada and an American Football player from Arizona who

joined the US Army and was killed in Afghanistan .

Work on the bridge started in 2005 and should finish next year. An

estimated 17,000 cars and trucks will cross it every day.

 

The dam was started in 1931 and used enough concrete to build a road from

New York to San Francisco . The stretch of water it created, Lake Mead , is

110 miles long and took six years to fill. The original road was opened at

the same time as the famous dam in 1936.

 

An extra note: The top of the white band of rock in Lake Mead is the old

waterline prior to the drought and development in the Las Vegas area. It is

over 100 feet above the current water level.

I hate bridges in the cage don't think I could make it on the bike:scared:

 

I used to work with a woman that actually planned trips around not having to go across a bridge. Bridges don't bother me, but the picture with the guys working on it made me feel better sitting here in my chair.

Same thing here. Never been over it on a bike. May sounds perfect. Later on in the year it starts getting hot. Something to look forward to....

Went across the dam in June of 06, was bumper to bumper traffic that day because they were pouring the pilings for the bridge at the sharp curve. 108 degrees and had to put rags over my clutch and brake handles because they were to hot to touch. Awesome sight, been wanting to go back ever since. Also when I decided I will always own a liquid cooled bike. There was a group of Harleys setting along side the road at the check point trying to cool their bikes. How are they supposed to cool down in the 108 degree sun?
