Arches have been used for centuries to build structures that supported heavy loads. Here are two examples. Above is a pedestrian bridge over Carroll Creek in downtown Frederick built about 5 years ago. Below is the Legore Bridge over the Monocacy River in the northern part of the county. James Legore built the bridge in 1900 to speed deliveries of stone from his quarry to customers in Pennsylvania. To see more geometry, go to Katney's Kaboodle.
I joined the Header Challenge team in November. We post a new header each week on a suggested theme. Imac is the founder and head of the team. The members vote for best header and the winner gets the gold. The links above will take you to the other participants.
This blog contains my posts for Our World Tuesday and Sky Watch Friday. Click on the logos below to reach the host site for these memes and links to a world full of great photographers. I also share photos, both present and past, on additional subjects. I may occasionally post photos taken by others and will so note ownership in the post.
My other two blogs can be viewed through the links below.

I have a bridge up, too, but mine are not quite as stoned as these. ;)
Seriously, these are beautiful bridges and you've show-cased them well.
I am home from my travels to the East, and Wednesday we move into our new home, finally, so you may once again be seeing me around!
Oh! Macro Monday & Geometry #4
If it weren't for arches and triangles, I don't knwo how the world would hold up.
