Conant Creek Pegram Truss Railroad Bridge
The Conant Creek Pegram Truss Railroad Bridge, in Fremont County, Idaho near Grainville, Idaho and Ashton, Idaho, was built in 1894. It brought a railroad over the Conant Creek, 1 mile south of the junction of Squirrel Rd. and the old Ashton-Victor railroad spur tracks. It is a Pegram truss bridge, designed by George H. Pegram. It was listed on the National Register of Historic Places in 1997. It now carries the Ashton-Tetonia Trail, and is known as the Conant Creek Trestle.Google maps.

The three central spans are pin-connected Pegram truss deck spans, each long and wide, with a maximum depth of . At each end are steel deck girders long at the north end and at the south end, and then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Falls, Idaho
American Falls is a city in and the county seat of Power County, Idaho. The population was 4,457 at the time of the 2010 census. History American Falls was a landmark waterfall on the Snake River, named after a party of American trappers whose boat went over the falls. The Wilson Price Hunt expedition in 1811 camped at the falls one night and the expedition of John C. Frémont was here in 1843. The Oregon Trail passed north of town, through the present-day reservoir. Power plants first sprang up at the falls in 1901. American Falls was the first town in the U.S. to be entirely relocated. It was moved in 1925 to facilitate construction of the nearby American Falls Dam. The old townsite sits at the bottom of the reservoir, northwest of the present city. A larger dam was completed in 1978, downstream from the deteriorating 1927 structure, which was later demolished. Geography American Falls is located at (42.781121, -112.855694), at an elevation of .

Bridges In Idaho
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss Bridges
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and the ...

National Park Service
The National Park Service (NPS) is an agency of the United States federal government within the U.S. Department of the Interior that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations. The U.S. Congress created the agency on August 25, 1916, through the National Park Service Organic Act. It is headquartered in Washington, D.C., within the main headquarters of the Department of the Interior. The NPS employs approximately 20,000 people in 423 individual units covering over 85 million acres in all 50 states, the District of Columbia, and US territories. As of 2019, they had more than 279,000 volunteers. The agency is charged with a dual role of preserving the ecological and historical integrity of the places entrusted to its management while also making them available and accessible for public use and enjoyment.

Union Bridge Company
The Union Bridge Company was a bridge fabricator and contractor with works in Buffalo, New York, (believed closed in 1890 per HAER references) and Athens, Pennsylvania. The Union Bridge company was formed in 1884 as a merger of several other bridge-building firms. Partners included George S. Field of Buffalo, Edmund B. Hayes of Buffalo, Charles MacDonald of New York City, Thomas C. Clarke of Seabright, NY and Charles Stewart Maurice of Athens, PA. History Kellogg, Clarke & Co. was formed in 1869 by Thomas C. Clarke and Charles Kellogg, with the backing of Samuel Reeves of the "Phoenix Iron Works" of Phoenixville, Pennsylvania. In 1871, Kellogg left to form his own company and Clarke and Reeves formed "Clarke, Reeves & Co." In 1884, "Clarke, Reeves & Co." became the "Phoenix Bridge Company." In the same year, Clarke and Charles Macdonald formed the ''Union Bridge Company'' by merger of the "Central Bridge Company" of Buffalo, New York and Kellogg and Maurice of Athens, Pennsylvania ...
