Madison, Wisconsin has many places set up for those who like to bike or go for walks. In fact, views are afforded to such alternative travelers that are not able to be seen by those in cars. Such is the case with Washington Bridge. A walking/bike path follows the Yahara River and goes directly under the bridge and avoiding any interaction with the busy vehicle traffic above.
For those individuals willing to take a few moments while traversing under the bridge, they are afforded a great interplay of line and value. I love how the "ribs" of the bridge reflect in the rather calm water.
Change your vantage point, move farther away from the light, or tilt your camera, and you've got a variety of abstract compositions.
