Driving home from Steilacoom, I went up the coast rather than cutting straight in to the interstate.  My route took me up towards the Tacoma Narrows bridges.  The original bridge is well know to any engineering student and many people will be familiar with the footage of it collapsing in moderate winds.  That bridge was replaced and, more recently, a second bridge was built alongside it.  In the early evening light, both bridges were nicely illuminated so I stopped to get a few shots.  Zooming in on the towers at the near end, I really liked the shapes of the towers and the pattern work on their surfaces.
