This photo is undated, but I think it must be 1957ish. The handwritten caption on the back reads,

“In bottom of canyon upstream from bridge. Concrete form for diversion tunnel shown here. To the bottom left is tunnel (mile plus long) which will connect the power house to top of canyon wall and to Page.”

Here’s the picture – a view I don’t think you’ll see anywhere but here – and one that is long since gone. Check it out. I’ll comment on it below.

There are a couple of things that need pointed out on this photo. The writing I cited above mentions a diversion tunnel and a tunnel that goes to the top of the canyon wall. Those are two different things. The opening mentioned on the left of the picture is the bottom of the tunnel that runs from there to the top of the canyon and comes out behind the old Country Club an golf course. That tunnel is still in use. The lower opening to the tunnel that you see in this picture is now on the downstream side of the dam and comes out near the power house. The next time you’re there, look down and you’ll see it. It’s interesting that the back caption says this tunnel WILL connect the top to the bottom, as it was still under construction at the time of this photo.

The concrete form mentioned in the picture is the round object on the right. There were two diversion tunnels that re-directed the Colorado River water around the dam site during construction. In future posts, I’ll be sharing some pictures with you of construction inside those diversion tunnels, as well as the upper spillways which connected to the diversion tunnels.

Notice the roadway in the center of the bridge and the road protruding out from the canyon on the right side. The present-day visitor’s center is located on the right side of this picture by the road. Also notice the netting that hung off the bottom of the bridge to catch falling workers and material. The cables that spanned the canyon are clearly visible and it looks like there is another roadway support being set at the time of this photo. This view is long gone!
