First Avenue South Bridge
The present day northbound span was built in 1956 to connect the industrial areas northeast of the Duwamish to the residential neighborhoods to the south and southwest. Between 1996 and 1998, the drawspan was retrofitted and the approaches completely demolished and rebuilt. The southbound span opened in February 1997 and carried traffic in both directions for two years while the northbound span was rebuilt.
In 2001, the southbound span was damaged by the Nisqually earthquake, knocking its piers 3 inches out of alignment, and was closed briefly for repairs.
From the original construction to February 1995 when the retrofit began, the First Ave S bridge had the highest motor vehicle accident rate in Washington State.
