Duwamish River

Lockheed Shipbuilding and Construction Company (a.k.a. Lockheed Shipbuilding), was a shipyard in Seattle, Washington with Yard 1 on Harbor Island and Yard 2 at what is now Jack Block Park at Seattle Terminal 5, both at the mouth of the West Waterway of Duwamish River. Yard 1 was founded in 1898 as the Puget Sound Bridge and Dredging Company, the company that built Harbor Island, and it was purchased by Lockheed in 1959. Yard 2 began operation in 1943 to build ships for the US Navy. The shipyard was permanently closed in 1988; Yard 2 was sold in 1989, and Yard 1 was sold in 1997, both to Port of Seattle.

Harbor Island is an artificial island in the mouth of the Duwamish River in Seattle, Washington, US, where it empties into Elliott Bay. Built by the Puget Sound Bridge and Dredging Company, it was completed in 1909 and was then the largest artificial island in the world, at 350 acres (1.4 km2). Since 1912, the island has been used for commercial and industrial activities including secondary lead smelting, shipbuilding and repair, bulk petroleum storage, metal fabrication and containerized cargo shipping. Warehouses, laboratories and other buildings are located on the island. Harbor Island was made from 24 million yd³ (18 million m³) of earth removed in the Jackson and Dearborn Street regrades and dredged from the bed of the Duwamish River.Harbor Island lost its title as the world's largest artificial island in 1938 with the completion of Treasure Island in San Francisco Bay, at 395 acres (1.60 km2). It regained the title in 1967, at which time its area had increased to nearly 397 acres (1.61 km2), but has now been far surpassed in area; since 2004, Rokkō Island in Kobe harbor in Japan is over 3.5 times larger. The official land area, as reported by the United States Census Bureau, was 406.91 acres (164.67 ha), at the 2000 census. There was also a permanent population of three persons reported on the island at that time. The West Seattle Bridge passes over the island, as does the newer Spokane Street Bridge, a swing bridge across the West Waterway. The East Waterway is crossed by a causeway supported a few feet above high tide by pilings. Vigor Industrial operates a 27-acre (10.9 ha) shipyard on the island, which is also the site of some of the Port of Seattle's terminals and the publishing branch of The Mountaineers (Mountaineering: The Freedom of the Hills, among others). The Seattle-Tacoma Shipbuilding Corporation built 45 destroyers for the United States Navy on the island from 1941 to 1946, in a yard now owned by Vigor.

Jack Block Park is a 15-acre (6.1 ha) park in the West Seattle neighborhood of Seattle, Washington, USA. Situated on the northwest corner of the Port of Seattle's Terminal 5, the park offers public beach access, a children's play area, and a 45-foot (14 m) observation tower.

The West Spokane Street Bridge was a pair of bascule bridges that crossed the west fork of the Duwamish River in Seattle, Washington, United States. The bridges connected the SoDo and West Seattle neighborhoods over the river. The original bridge opened to traffic in 1924; a second bridge carrying eastbound traffic was opened in 1930, with the 1924 bridge reconfigured to carry westbound traffic. Both bridges carried traffic until 1978, when a freighter rammed into the 1924 bridge; the 1930 bridge was subsequently reconfigured to handle two-way traffic as a result. The 1930 bridge was replaced in official capacity by the higher-level Jeanette Williams Memorial Bridge (a.k.a. the West Seattle Bridge) in 1984. The 1930 span of the bridge was closed in 1989 and subsequently demolished to make way for a lower swing bridge connecting West Seattle to Harbor Island (now known as the Spokane Street Bridge, which opened in 1991).

At 2:38 a.m. on June 11, 1978, the freighter Antonio Chavez rammed the West Spokane Street Bridge, thereby closing it to automobile traffic for the next six years. The pilot and master were both found negligent in causing the collision. The collision led to the opening of the current West Seattle Bridge in 1984. The incident occurred in west fork of the Duwamish Waterway, as the Chavez hit the West Spokane Street Bridge which had been raised to allow the ship to pass through. This blocked eastbound traffic to West Seattle, until the westbound span was temporarily adapted to handle two-way traffic.

The West Seattle Bridge, officially the Jeanette Williams Memorial Bridge, is a cantilevered segmental bridge that serves as the primary connection between West Seattle and important highways such as State Route 99 (and the tunnel through downtown), the Spokane Street Viaduct, and Interstate 5. It was built between 1981 and 1984 after the previous bascule bridge was deemed inoperable as a result of being struck by the freighter Antonio Chavez in 1978. The high-level bridge was closed in March 2020 after cracks in the underside were found to be growing rapidly, necessitating a major repair amid the COVID-19 pandemic. The Seattle Department of Transportation conducted repairs over a two-year period and reopened the bridge on September 17, 2022.

J. F. Duthie & Company was a small shipyard located on the east side of Harbor Island in Seattle, Washington. It was reportedly organized in 1911 (although there is no mention of it on the 1912 Baist map at the location where the shipyard would be built) and expanded to 4 slipways on 25 acres of property in World War I to build cargo ships for the United Kingdom, France and Norway, but those resources were eventually all diverted at the behest of the United States Shipping Board (USSB). Work on the new plant started on 10 September 1916 and the first keel was laid on 29 November the same year. At that time, the new Skinner & Eddy plant across the water was already launching its first two ships: Niels Nielsen (21 September) and Hanna Nielsen (23 October). Some 24 of the 33 ships built at J. F. Duthie were the "West boats," a series of steel-hulled cargo ships built for the USSB on the West Coast of the United States as part of the World War I war effort, with 12 requisitioned and 12 built under contract, 16% of the steel tonnage built in Puget Sound for the USSB. Duthie was supplied with boilers by Willamette Iron and Steel Works of Portland, Oregon.After the war, Wallace F. Duthie, the son of the founder J. F. Duthie, organized the dismantling of the shipbuilding facilities. Wallace died in 1922 at age 23.In 1928 the company's name was changed to Wallace Bridge Company. It built structural steel for local projects, including the Washington Athletic Club building in 1930.

Seacrest Cove 2 also known as Alki Cove 2 is a local dive site in West Seattle, Washington. The site within Seacrest Park is the most popular diving location in Seattle.Cove 2 is often used as a training site for open water, navigation and other scuba classes. The site has a moderate slope leading down to depths greater than the recreational limit of 130 feet (40 meters). Because of the easily reached deep areas, technical divers also use Cove 2 for training. The site has a silty bottom, but many submerged logs, pilings and sunken boats (the Honey Bear) that are well decorated with Pacific Northwest marine life. There are restrooms in the pier building. The site has a view of the Seattle skyline across Elliott Bay. There is an exclusion zone of 150 feet around the walk-on ferry dock. Other sites (Coves 1 and 3) are just to the north and south respectively. Most parking is curbside on the street.

The Skinner & Eddy Corporation, commonly known as Skinner & Eddy, was a Seattle, Washington-based shipbuilding corporation that existed from 1916 to 1923. The yard is notable for completing more ships for the United States war effort during World War I than any other American shipyard, and also for breaking world production speed records for individual ship construction. In total, the company built 75 ships—72 cargo ships and three oil tankers—from 1916 to 1920, including 32 completed for the Emergency Fleet Corporation during the war. The yard was closed in 1921 as a result of the severe postwar shipbuilding slump. Skinner & Eddy later became a shipping line operator, and appears to have been wound up in the early 1970s.

The Elliot Bay Petroglyphs, also known as 45KI23, are petroglyphs created before recorded times by the Duwamish people in present-day Seattle. According to various archaeological reports (involved in Washington State Route 519 and other works), the petroglyphs "at the southern end of Elliott Bay near the mouth of the Duwamish River", today in Seattle's Industrial District, may have been buried or stolen when the Duwamish estuary and tidal flats were developed and filled during settlement of the city. Richard McClure, a researcher from The Evergreen State College described the inscriptions as "pecked figures of a zoomorphic nature".

Frank B. Cooper Elementary School, usually called Cooper School, serves students from kindergarten through 5th grade. Located in the Pigeon Point neighborhood of Delridge, Seattle, Washington, it is part of the Seattle Public Schools district. The school's 14-acre (57,000 m2) site is immediately adjacent to the 182-acre (0.74 km2) West Duwamish Greenbelt, one of Seattle's largest wildlife habitat corridors. This rich natural environment enhances the school's environmental education program. While the current building, located at 1901 SW Genesee Street, was opened in 1999, Cooper School enjoys a long history in the community, dating back to 1906, when a group of 70 students, children of steel mill workers, attended classes at Youngstown School in a small building offered by the Seattle Steel Company. A year later, a wooden building—known as Riverside School—was built for the school at the base of Pigeon Hill. As the population of the community grew, the wooden structure was replaced by a brick building 1917, which was designed by Edgar Blair, with a 1929 expansion designed by Floyd Naramore. In 1939, the school was renamed to honor Frank B. Cooper, a former Seattle school superintendent. The historic Youngstown School building, located at 4408 Delridge Way SW, now houses the Cooper Artist Housing and Youngstown Cultural Arts Center. It is listed in the National Register of Historic Places.One of the school's assets is its diversity. Approximately 80 percent of Cooper students are racial or ethnic minorities and approximately one-quarter are bilingual. The first African American teacher hired to teach in Seattle Public Schools, Thelma Dewitty, worked at Cooper School from 1947 until 1953. The Thelma DeWitty Theater at the Youngstown Cultural Arts Center is named after her. On Thursday January 29, 2009 the Seattle School Board voted to close Cooper Elementary School and move the Pathfinder K-8 program to the Cooper campus.

Elliott Bay is a part of the Central Basin region of Puget Sound. It is in the U.S. state of Washington, extending southeastward between West Point in the north and Alki Point in the south. Seattle was founded on this body of water in the 1850s and has since grown to encompass it completely. The waterway it provides to the Pacific Ocean has served as a key element of the city's economy, enabling the Port of Seattle to become one of the busiest ports in the United States.
