It's Geometry #3

Follow the lines.

The fence line and the line of the bridge.

Bridgemakers make efficient use of geometry. No matter the style of bridge, you will find triangles for strength, and lots of other lines and shapes as well.

Paulie had a neat bridge last week--also over the Columbia River but  hundreds of miles downstream from this one--a different style, but full of triangles and other shapes. We posted bridges one Monday a month for some time. If you are interested, click the Bridges between link in my lable cloud.
