Ship Canal Bridge
The Ship Canal Bridge is a double-deck steel truss bridge that carries Interstate 5 (I-5) over Seattle's Portage Bay (part of the Lake Washington Ship Canal, after which it is named) between Capitol Hill and the University District. The canal below connects Lake Union with Lake Washington. Construction was completed in 1961 and the bridge opened to traffic on December 18, 1962.Centralia Daily Chronicle Newspaper, December 19, 1962 It is 4,429 ft (1,350 meters) long, stands 182 feet above the canal and is 119 feet wide at the upper deck. It was the largest bridge of its kind in the Northwest when it first opened. The bridge is double-decked, with the upper deck carrying traffic in both directions and the lower deck (the express lanes) carrying traffic southbound in the morning and northbound in the afternoon. Other nearby bridges include University Bridge, Montlake Bridge, and George Washington Memorial Bridge The Aurora Bridge (officially called the George Wash ...

University Bridge (Seattle)
The University Bridge is a double-leaf bascule bridge in Seattle, Washington that carries Eastlake Avenue traffic over Portage Bay between Eastlake to the south and the University District to the north. It opened on July 1, 1919, and was extensively rebuilt from 1932 to 1933. It is included in the National Register of Historic Places. History The bridge opened in 1919 under the name of ''Eastlake Avenue Bridge'' (also then known as the ''Tenth Avenue Northeast Bridge''). It got its current and proper name on June 30, 1919. By 1930, the bridge had begun to deteriorate enough for an extensive refit to be ordered: the timber trestle approaches were replaced with ones made out of concrete and steel, the control towers were rebuilt, and the wooden paving was replaced by the first application of open steel-mesh grating in the United States. Wooden paving had to be replaced every ten years or so; the steel-mesh grating has been replaced once, in 1990. The reconstructed bridge was open ...

Bridges On The Interstate Highway System
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use.

Truss Bridges In The United States
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

Steel Bridges In The United States
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bridges In Washington (state)
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", ...

Bridges In Seattle
The city of Seattle, Washington, United States, has multiple bridges that are significant due to their function, historical status, or engineering. Bridges are needed to cross the city's waterways and hilly topography. Twelve bridges have been granted historical status by the city, federal government, or both. Seattle also has some of the only permanent floating pontoon bridges in the world. Original crossings over Seattle's mudflats were typically supported by timber piles. Lake Washington and Puget Sound are to the east and west of the city, respectively. They connect via a series of canals and Lake Union that are collectively known as the Lake Washington Ship Canal. The four double-leaf bascule bridges crossing the Ship Canal are the oldest still used in the city, having opened between 1917 and 1930. The easternmost—the Montlake and University bridges—connect neighborhoods south of the canal to the University District. The Fremont Bridge crosses the center of the ...

Montlake Bridge
The Montlake Bridge is a double-leaf bascule bridge that carries State Route 513 (Montlake Boulevard) over Seattle's Montlake Cut—part of the Lake Washington Ship Canal—connecting Montlake and the University District. It is the easternmost bridge spanning the canal. The bridge is long, and was designed by Carl F. Gould, one of the original architects of the University of Washington campus. The bridge and its control towers were designed in conjunction with the university's Collegiate Gothic style. It provides a clearance of and is reported as providing of vertical clearance above the mean regulated level of Lake Washington for the central of the bascule span. It is one of four original bascule-type drawbridges over the Ship Canal, the others being the Ballard, Fremont, and University bridges. It was the last one to be completed, has the highest clearance of the four, and is the only one that is part of the state highway system. It is also one of six bascule bridges ...

Lake Washington
Lake Washington is a large freshwater lake adjacent to the city of Seattle. It is the largest lake in King County and the second largest natural lake in the state of Washington, after Lake Chelan. It borders the cities of Seattle on the west, Bellevue and Kirkland on the east, Renton on the south and Kenmore on the north, and encloses Mercer Island. The lake is fed by the Sammamish River at its north end and the Cedar River at its south. Lake Washington received its present name in 1854 after Thomas Mercer suggested it be named after George Washington, as the new Washington Territory had been named the year before. Earlier names for the lake include the Duwamish name ''Xacuabš'' ( Lushootseed: literally "''xacu''" ''great-amount-of-water + "abš" people''), which referred to peoples who stayed along the coastline of Lake Washington, as well as Lake Geneva by Isaac N.
