It's Geometry Monday!

Just a reminder that I actually posted my Monday's Geometry on Saturday--along with my Weekend Reflection.

But here's another bit of amazing use of geometry in engineering from my Dad's album.

You know, I don't really care how many triangles make that strong, to me, that is one scary looking bridge. It spanned the Snake River at Twin Falls, Idaho, and was replaced in 1974 with the one I featured here, which gives me a lot more confidence. At the time this picture was taken, it was the highest bridge in the world. (I wrote about that, too.)

And look--both a reflection and a shadow as well. Thanks, Dad.

Blue Bridge Reflection

We wandered along the Columbia River at Columbia Park in Kennewick the other day. This is the Blue Bridge. That is its name--at least the only one I have ever heard it called by. (Here's another view from a while back of the Blue Bridge--you can see that it really is blue.)

Looking the opposite way along the river we could see these Three Bridges. One of them, the Cable Bridge, we crossed on another occasion.

Back to the bridges

Back in February when we were doing the Bridges Between meme I posted this picture of my Dad's here.
At the time the picture was taken in 1929, the bridge at Twin Falls, Idaho was the highest bridge in the world, in the sense that it was highest above the river below. The post explored other senses of being highest.








This morning we crossed the bridge in that spot which was built in 1974.
