East 21st Street Bridge
The East 21st Street Bridge is a or or long cable-stayed bridge in Tacoma, Washington completed in January 1997. The bridge, whose most significant feature is two tall towers, carries four lanes State Route 509 (SR 509) across the Thea Foss Waterway from downtown Tacoma to the Port of Tacoma. SR 509 ends at a single point urban interchange with Interstate 705 west of the bridge, built as part of the same $165.3 million WSDOT project that also funded the bridge's construction. The architect for the bridge was Jim Merritt, a Tacoma architect. It is sometimes called Foss Waterway Bridge, although the Murray Morgan Bridge The Murray Morgan Bridge, also known as the 11th Street Bridge or City Waterway Bridge, is a vertical-lift bridge in Tacoma, Washington.

Thea Foss Waterway
The Thea Foss Waterway, formerly the City Waterway, is a north–south inlet of Commencement Bay separating downtown Tacoma, Washington, from the Port of Tacoma. History The City Waterway was created in 1902 through a dredging operation proposed by the Northern Pacific Railway and led by the U.S. Army Corps of Engineers. An existing inlet was widened to for that era's wheat ships and extended south, while a fork of the Puyallup River (now the Wheeler–Osgood Waterway) was severed. In 1989, the waterway was renamed to honor Thea Foss, who founded the Foss Maritime Company on the inlet in 1889. Cleanup and redevelopment During the early 20th century, the Thea Foss Waterway was a thriving industrial center. Industry began to dwindle in the area, and by 1981, the Thea Foss Waterway was almost entirely abandoned. In 1983, the United States Environmental Protection Agency (EPA) listed the Thea Foss and Wheeler-Osgood waterways as part of the larger Commencement Bay Superfund site. ...

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north.

Cable-stayed Bridge
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges were being designed and constructed by the late 16th century, and the form found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed ...

Port Of Tacoma
The Port of Tacoma is an independent seaport located in Tacoma, Washington. The port was created by a vote of Pierce County citizens on November 5, 1918. The ''Edmore'' was the first ship to call at the port in 1921. The port's marine cargo operations, among the largest in the United States, was merged with the Port of Seattle's in 2015 to form the Northwest Seaport Alliance.

Single Point Urban Interchange
A single-point urban interchange (SPUI, or ), also called a single-point interchange (SPI) or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space safely and efficiently. Description A SPUI is similar in form to a diamond interchange but has the advantage of allowing opposing left turns to proceed simultaneously by compressing the two intersections of a diamond into one single intersection over or under the free-flowing road. The term "single-point" refers to the fact that all through traffic on the arterial street, as well as the traffic turning left onto or off the interchange, can be controlled from a single set of traffic signals. Due to the space efficiency of SPUIs relative to the volume of traffic they can handle, the interchange design is being used extensively in the reconstruction of existing freeways as well as constructing new freeways, p ...

Murray Morgan Bridge
The Murray Morgan Bridge, also known as the 11th Street Bridge or City Waterway Bridge, is a vertical-lift bridge in Tacoma, Washington. It originally opened February 15, 1913, to replace an 1894 swing-span bridge. The bridge connects downtown with the tidal flats, it spans the Thea Foss Waterway, originally known as the City Waterway. Designed by noted bridge engineering firm Waddell & Harrington, the bridge has some unusual features: higher above the water than most lift bridges, construction on a variable grade and an overhead span designed to carry a water pipe. The bridge structure also contained a series of switchback ramps that connected what is now Cliff Street with Dock Street. According to the Department of Transportation, the towers are above the water, with the road deck above the water level at zero tide. It was modified and updated in 1957 and was used to route State Route 509 through the tidal flats. The bridge was bypassed in the late 1990s when State Route 509 w ...

National Bridge Inventory
The National Bridge Inventory (NBI) is a database, compiled by the Federal Highway Administration, with information on all bridges and tunnels in the United States that have roads passing above or below them. That is similar to the grade-crossing identifier number database, compiled by the Federal Railroad Administration, which identifies all railroad crossings. The bridge information includes the design of the bridge and the dimensions of the usable portion. The data is often used to analyze bridges and to judge their condition. The inventory is developed for the purpose of having a unified database for bridges to ensure the safety of the traveling public, as required by the Federal Aid Highway Act of 1968. It includes identification information, bridge types and specifications, operational conditions, bridge data including geometric data and functional description, and inspection data. Any bridge more than 20 ft (6 m) long used for vehicular traffic is included. Description Iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
