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 bridge opened to traffic in 1917 as a single bridge carrying two-way traffic. A second, twin bridge opened in 1958 with each bridge carrying one-way traffic. The original 1917 structure is the northbound bridge. As of 2006, the bridge pair handles around 130,000 vehicles daily. The green structure, which is over long, carries traffic over three northbound lanes and three southbound lanes. It was added to the National Register of Historic Places in 1982, as the "Portland–Vancouver Highway Bridge". Since 2005, proposals for replacing the bridge have been produced and debated. The bridge is considered responsible for traffic cong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. It was built in 1939. The bridge was the primary route between Lewiston and Clarkston, until the Southway Bridge was constructed in the 1980s.

Federal Transit Administration
The Federal Transit Administration (FTA) is an agency within the United States Department of Transportation (DOT) that provides financial and technical assistance to local public transportation systems. The FTA is one of ten modal administrations within the DOT. Headed by an Administrator who is appointed by the President of the United States, the FTA functions through Washington, D.C headquarters office and ten regional offices which assist transit agencies in all states, the District of Columbia, and the territories. Until 1991, it was known as the Urban Mass Transportation Administration (UMTA). Public transportation includes buses, subways, light rail, commuter rail, monorail, passenger ferry boats, trolleys, inclined railways, and people movers. The federal government, through the FTA, provides financial assistance to develop new transit systems and improve, maintain, and operate existing systems. The FTA oversees grants to state and local transit providers, primarily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Foundation
A deep foundation is a type of 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. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. 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 caissons. Piles are generally driven into the ground in situ; other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering di ...

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 to ... [...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 of the pier is square, or rectangular, but other shapes are also common. In medieval architecture, massive 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 buildings with a sequence of 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 resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support the ends of spans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon Historical Society
The Oregon Historical Society (OHS) is an organization that encourages and promotes the study and understanding of the history of the Oregon Country, within the broader context of U.S. history. Incorporated in 1898, the Society collects, preserves, and makes available materials of historical character and interest, and collaborates with other groups and individuals with similar aims. The society operates the Oregon History Center that includes the Oregon Historical Society Museum in downtown Portland. History The Society was organized on December 17, 1898, in Portland at the Portland Library Building.Corning, Howard M. ''Dictionary of Oregon History''. Binfords & Mort Publishing, 1956. Its mission, as expressed in the first volume of its '' Oregon Historical Quarterly'', was to "bring together in the most complete measure possible the data for the history of the commonwealth, and to stimulate the widest and highest use of them." The first president was Harvey W. Scott, with mem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multnomah County, Oregon
Multnomah County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the county's population was 815,428. Multnomah County is part of the Portland– Vancouver– Hillsboro, OR–WA Metropolitan Statistical Area. Though smallest in area, Multnomah County is the state's most populous county. Its county seat, Portland, is the state's largest city. History The area of the lower Willamette River has been inhabited for thousands of years, including by the Multnomah band of Chinookan peoples long before European contact, as evidenced by the nearby Cathlapotle village, just downstream. Multnomah County (the thirteenth in Oregon Territory) was created on December 22, 1854, formed out of two other Oregon counties – the eastern part of Washington County and the northern part of Clackamas County. Its creation was a result of a petition earlier that year by businessmen in Portland complaining of the inconvenient location of the Washington County s ...

Ferry
A ferry is a ship, watercraft or amphibious vehicle used to carry passengers, and sometimes vehicles and cargo, across a body of water. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi. 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 Mediterranean Sea) may also be called ferry services, and many carry vehicles. History In ancient times 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
