The Industrial District is the principal industrial area of Seattle, Washington. It is bounded on the west by the Duwamish River and Elliott Bay, beyond which lies Delridge of West Seattle; on the east by Interstate 5, beyond which lies Beacon Hill; on the north by S King and S Dearborn Streets, beyond which lie Pioneer Square and southwest International District of Downtown; and on the south by the main lines of the BNSF Railway and Union Pacific Railroad, or about S Lucille Street, beyond which is Georgetown. SoDo is the name of the northwest portion of the neighborhood, named for its being South of Downtown. SoDo is the location of T-Mobile Park, home of the Seattle Mariners, and Lumen Field, home of the Seattle Seahawks and Seattle Sounders FC. Lumen Field was also the site of the former Kingdome.
The Industrial District may also be defined by land use, with the primarily residential and open space Delridge district extending west from W Marginal Way SW and south of SW Spokane Street, and with the heavy industrial-zoned lower Duwamish River east of Marginal and north of Spokane as part of the Industrial District.Most of the Industrial District is built on what was once the mudflats and lowlands of Elliott Bay and the Duwamish estuary, dredged, straightened, and filled 1902 and 1907. Much of the area is also built on landfill which is prone to liquefaction. This makes buildings in this area highly prone to earthquake damage.Principal arterials are First and Fourth Avenues S, Alaskan Way, East Marginal and Airport Ways S (north- and southbound); and S Spokane, the Spokane Street Viaduct, West Seattle Bridge, and S Royal Brougham Way (east- and westbound; Royal Brougham was formerly S Atlantic Street). Minor arterials are 6th Avenue S, S Holgate and S Lander Streets, and S Industrial Way.
