Burlington Northern Railroad Bridge 5.1
The Burlington Northern Railroad Bridge 5.1 or BNSF Railway Bridge 5.1, also known as the St. Johns Railroad Bridge or the Willamette River Railroad Bridge, is a through truss railway bridge with a vertical lift that spans the Willamette River in Portland, Oregon, United States. Built by the Spokane, Portland and Seattle Railway (SP&S) and completed in 1908, it was originally a swing-span bridge, and its swing-span section was the longest in the world at the time. However, 81 years later the main span was converted from a swing-type to a vertical-lift type, in order to widen the navigation channel. The lift span is one of the highest and longest in the world. The bridge consists of five sections, with the two sections closest to the bank on each side fixed. The BNSF Railway owns the bridge, and the 5.1 denotes the distance in miles from Portland's Union Station or from the nearby North Bank Depot (or Hoyt Street Depot), which was the Portland terminus of SP&S passenger service ...

Bascule Bridge
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Portland (Oregon)
The Port of Portland is the port district responsible for overseeing Portland International Airport, general aviation, and marine activities in the Portland, Oregon metropolitan area in the United States. Originally established in 1891 by the 16th Oregon Legislative Assembly, the current incarnation was created by the 1970 legislature, combining the original Port with the Portland Commission of Public Docks, a city agency dating from 1910.

Madison Street Bridge (Portland, Oregon)
The Madison Street Bridge, or Madison Bridge, refers to two different bridges that spanned the Willamette River in Portland, Oregon, from 1891 to 1900 and from 1900 to 1909. The bridges connected Madison Street, on the river's west bank, and Hawthorne Avenue, on the east bank, on approximately the same alignment as the existing Hawthorne Bridge. The original and later bridges are sometimes referred to as Madison Street Bridge No. 1 and Madison Street Bridge No. 2, respectively.Wood Wortman (2006), pp. 6, 13, 62. The second bridge, built in 1900, has alternatively been referred to as the "rebuilt"Bottenberg (2007), pp. 29–30. Madison Street Bridge (of 1891), rather than as a new bridge, because it was rebuilt on the same piers.

Morrison Bridge
The Morrison Bridge is a bascule bridge that spans the Willamette River in Portland, Oregon. Completed in 1958, it is the third bridge at approximately the same site to carry that name. It is one of the most heavily used bridges in Portland. It was added to the National Register of Historic Places in November 2012.

Burnside Bridge
The Burnside Bridge is a 1926-built bascule bridge that spans the Willamette River in Portland, Oregon, United States, carrying Burnside Street. It is the second bridge at the same site to carry that name. It was added to the National Register of Historic Places in November 2012. Design The bridge was designed by Ira G. Hedrick and Robert E. Kremers, incorporating a bascule lift mechanism designed by Joseph Strauss. Including approaches, the Burnside has a total length of and a center span. While lowered this span is normally above the river. The deck is made of concrete, which contributes to its being one of the heaviest bascule bridges in the United States. The counterweights, housed inside the two piers, weigh . The lifting is normally controlled by the Hawthorne Bridge operator, but an operator staffs the west tower during high river levels. As of 2005, the bridge opened for river traffic an average of 35 times a month. The bridge provides shelter for the initially un ...

Oregon Slough Railroad Bridge
The Oregon Slough Railroad Bridge, also known as the BNSF Railway Bridge 8.8, is a swing-span, through truss bridge in Portland, Oregon, United States. Currently owned and operated by BNSF Railway, it crosses an anabranch of the Columbia River known as North Portland Harbor and historically as the Oregon Slough. The bridge's northern end is on Hayden Island, which, along with Tomahawk Island, forms the north shore of the channel. Completed in 1908, the two-track bridge is one of only two swing bridges surviving in Portland, which once had several bridges of that type, both for road and rail traffic. The only other remaining swing bridge in the Portland area is another rail-only bridge on the same line, BNSF's nearby Bridge 9.6, spanning the Columbia River. The bridge is used regularly by freight trains of both BNSF and Union Pacific Railroad, as well as by Amtrak passenger trains on routes connecting Portland with Seattle and with Chicago via Spokane, Washington.

Oregon Railroad And Navigation Company
The Oregon Railroad and Navigation Company (OR&N) was a railroad that operated a rail network of running east from Portland, Oregon, United States, to northeastern Oregon, northeastern Washington, and northern Idaho. It operated from 1896 as a consolidation of several smaller railroads. OR&N was initially operated as an independent carrier, but Union Pacific (UP) purchased a majority stake in the line in 1898. It became a subsidiary of UP titled the Oregon–Washington Railroad and Navigation Company in 1910. In 1936, Union Pacific formally absorbed the system, which became UP's gateway to the Pacific Northwest.
