This is my entry, for Monochrome Madness Challenge. The theme is Bridge.
The Salmon Bay Bridge, also known as Bridge No. 4, is a single-leaf bascule bridge spanning across Salmon Bay and connecting Magnolia/Interbay to Ballard in Seattle, Washington. I took lots of photos as we waited for our turn to go through.
