Interstate Bridge
The Interstate Bridge (also Columbia River Interstate Bridge, I-5 Bridge, Portland-Vancouver Interstate Bridge, Vancouver-Portland Bridge) is a pair of nearly identical steel vertical-lift, Parker through-truss bridges that carry Interstate 5 traffic over the Columbia River between Vancouver, Washington and Portland, Oregon in the United States. The present-day northbound bridge opened to traffic in 1917 as a single bridge carrying two-way traffic. A second twin bridge, which carries southbound traffic, opened in 1958. The twin bridges are each over long and carry three lanes of traffic. The bridges handle a combined 130,000 vehicles daily. It was added to the National Register of Historic Places in 1982, as the "Portland–Vancouver Highway Bridge". Since 2005, several proposals for replacing the bridge have been produced and debated. The bridge is considered responsible for traffic congestion of both road and river vehicles. Plans for a replacement bridge, known as the ...

Interstate Highway Bridge
The Interstate Highway Bridge crosses the Snake River, between Clarkston, Washington and Lewiston, Idaho. The bridge carries U.S. Route 12 (US 12) across the state line between Washington and Idaho, and is maintained by the Washington State Department of Transportation. It was built in 1939 and is long. It is nicknamed the "Blue Bridge" locally. The bridge was the primary route between Lewiston and Clarkston, until the Southway Bridge was constructed in the 1980s.

The FTA oversees grants to state and local transit providers, primari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Foundation
A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. A deep foundation is a type of foundation (architecture), foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and Caisson (engineering), caissons. Piles are generally driven into the ground ''in situ''; other deep foundations are typically put in place using excavation and drilling. The namin ...

Pile Cap
A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation. It usually forms part of the deep foundation of a building, typically a multi-story building, structure or support base for heavy equipment, or of a bridge. The cast concrete pile cap distributes the load of the building into the piles. A similar structure to a pile cap is a "raft", which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence. Design Construction The mat is made of concrete which is an aggregate of small rocks and cement. This mixture has to be supported by a framework to avoid sagging and fracture while setting. This process is known as shuttering and reinforcing. The materials used are long steel bars with longitudinal protrusions between the piles held in shape by thinner tie wires. Once this steel mat is laid, timber is attached around the perimeter t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pier (architecture)
A pier, in architecture, is an upright support for a structure or superstructure such as an arch or bridge. Sections of structural walls between openings (bays) can function as piers. External or free-standing walls may have piers at the ends or on corners. Description The simplest cross section (geometry), cross section of the pier is square (geometry), square, or rectangle, rectangular, but other shapes are also common. In medieval architecture, massive circle, circular supports called drum piers, cruciform (cross-shaped) piers, and compound piers are common architectural elements. Columns are a similar upright support, but stand on a round base; in many contexts columns may also be called piers. In buildings with a sequence of Bay (architecture), bays between piers, each opening (window or door) between two piers is considered a single bay. Bridge piers Single-span bridges have abutments at each end that support the weight of the bridge and serve as retaining walls to res ...

Ferry
A ferry is a boat or ship that transports passengers, and occasionally vehicles and cargo, across a body of water. A small passenger ferry with multiple stops, like those in Venice, Italy, is sometimes referred to as a water taxi or water bus. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Baltic Sea) may also be called ferry services, and many carry vehicles. History The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it could not work and such a ferry, mod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
