Oregon City Bridge
The Oregon City Bridge, also known as the Arch Bridge, is a steel through arch bridge spanning the Willamette River between Oregon City and West Linn, Oregon, United States. Completed in 1922, it is listed on the National Register of Historic Places. It was built and is owned by the Oregon Department of Transportation (ODOT) as part of Oregon Route 43 and is the thirdsouthernmost Willamette bridge in the Portland metropolitan area, after the Boone Bridge in Wilsonville and the Oregon 219 bridge near Newberg. The bridge is 745 ft (227 m) in length and 28 ft (8½ m) wide with a 360 ft (110 m) long main span that provides 49 ft (15 m) of vertical clearance at low river levels. The narrow width causes problems for large vehicles that cross it, often requiring traffic going in the other direction to stop. TriMet buses ceased using the bridge in 2009. This bridge is the only Oregon bridge to be encased in gunite, which protects it from corrosive sulfur diox ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willamette River
The Willamette River ( ) is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia. Originally created by plate tectonics about 35 million years ago and subsequently altered by volcanism and erosion, the river's drainage basin was significantly modified by the Missoula Floods at the end of the most recent ice age. Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth on the Columbia. Indigenous peoples lived throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper Mill
A paper mill is a factory devoted to making paper from vegetable fibres such as wood pulp, old rags, and other ingredients. Prior to the invention and adoption of the Fourdrinier machine and other types of paper machine that use an endless belt, all paper in a paper mill was made by hand, one sheet at a time, by specialized laborers. History Historical investigations into the origin of the paper mill are complicated by differing definitions and loose terminology from modern authors: Many modern scholars use the term to refer indiscriminately to all kinds of mills, whether powered by humans, by animals or by water. Their propensity to refer to any ancient paper manufacturing center as a "mill", without further specifying its exact power source, has increased the difficulty of identifying the particularly efficient and historically important water-powered type. Human and animal-powered mills The use of human and animal powered mills was known to Muslim and Chinese paperma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon City Bridge Under Construction
Oregon () is a state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as the strait now bearing his name. Spanish ships – 250 in as many years – would typically not land before reaching Cape Mendocino i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Willamette Falls Locks
The Willamette Falls Locks are a lock system on the Willamette River in the U.S. state of Oregon. Opened in 1873 and closed since 2011, they allowed boat traffic on the Willamette to navigate beyond Willamette Falls and the T.W. Sullivan Dam. Since their closure in 2011 the locks are classified to be in a "non-operational status" and are expected to remain permanently closed. Located in the Portland metropolitan area, the four inter-connected locks are 25 miles upriver from the Columbia River at West Linn, just across the Willamette River from Oregon City. The locks were operated by the United States Army Corps of Engineers and served primarily pleasure boats. Passage through the locks was free for both commercial and recreational vessels. The locks were added to the National Register of Historic Places in 1974 and designated as an Oregon Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1991.
