Pier 1, now-demolished pier on the Seattle Waterfront

Pier 1 is a cargo pier in Seattle that extends into the water and once served as a docking point for ships. The structure consists of steel and wood and was equipped with large warehouses where goods were stored before being loaded onto railcars.

Pier 1 was built in the early 1900s, around 1901 to 1904, replacing the older Yesler's Wharf. In the 1940s, a pier numbering system was introduced, and during World War II, the military used many piers for its operations.

Pier 1 no longer exists: it was demolished in the early 1980s to make room for the expanded Washington State Ferries terminal at Pier 52, Colman Dock. The site stood at the foot of Washington Street, between Pier A to the south and Pier 2 to the north. Visitors today find the ferry terminal there instead.

From 1949 until September 17, 1960, Nippon Yusen Kaisha's Hikawa Maru called at this pier; it was the only Japanese passenger ship to survive World War II. The pier was demolished in the early 1980s to expand the Washington State Ferries terminal at Colman Dock (Pier 52).
