Opening in 1917, the Fremont Bridge crosses the Lake Washington Ship Canal and connects the Fremont and Queen Anne neighborhoods. In 2005, the bridge underwent a major overhaul to renovate its mechanical and electrical systems. Remnants of this renovation, such as these gears, are scattered around the Fremont neighborhood.

Unlike most of my urban sketches, this is a pure contour drawing, which involves working part to part, and requires careful observation and deliberate line work.
