Lewis And Clark River Bridge
The Lewis and Clark River Bridge is a bascule bridge that spans the Lewis and Clark River on U.S. Route 101 Business (a section originally part of U.S. Route 101) in Clatsop County, Oregon. It was designed by Conde McCullough and opened in 1925."New Span to Be Opened" (March 7, 1925). ''The Morning Oregonian'' (Portland), p. 1. It was built to replace an earlier bridge at the same location,"About $11,000,000 Spent on Highways" (and section heading: "Bridges Are Built"). (December 9, 1923). '' The Sunday Oregonian'', p. 13. a swing-span bridge constructed around 1910. The total length of the bridge is , and the length of the bascule main span is . The approach spans consist of a total of 48 timber pile and stringer spans.Hadlow (2001), p. 141.

Lewis And Clark River
The Lewis and Clark River is a tributary of Youngs River, approximately long, in northwest Oregon in the United States. It drains of the Northern Oregon Coast Range in the extreme northwest corner of the state, entering Youngs River just above its mouth on the Columbia River at Youngs Bay. Near the river's mouth is the site of former Fort Clatsop of the Lewis and Clark Expedition. The river is named for Meriwether Lewis and William Clark. History and parks The river was called the Netul River by Lewis and Clark and the Native American Clatsop people who were living in the area at the time. It continued to be known as the Netul River until 1925, when it was renamed to honor Lewis and Clark. The river flows through Lewis and Clark National Historical Park, which was designated as a National Historical Park in 2004. Fish The river is home to bottom-feeding white sturgeon, which is a sport fish in the area. It is also home to an extensive salmon repopulation program, just outside ...

Bridges Of The United States Numbered 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. Etymology The ''Oxford English Dictionary'' traces the origin of the w ...

Historic American Engineering Record In Oregon
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Road Bridges In Oregon
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", which i ...

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Astoria, Oregon
Astoria is a port city and the seat of Clatsop County, Oregon, United States.
