Gunnison River Bridge I
Gunnison River Bridge I and Gunnison River Bridge II are two long bridges built during 1926–27. They were separately listed on the National Register of Historic Places in 2002. The bridges carry what is now the U.S. Highway 50 service road. Bridge I brings it over Gunnison River overflow at mileposts 155.41 and Bridge II, at 155.59, brings it over the Gunnison River proper. The bridges are located at (Bridge I, further to the west, spanning overflow) and (Bridge II, further to the east, spanning the main river). The two bridges are Pratt truss through truss bridges, long. Their trusses were fabricated by the American Bridge Company. With . With .

Gunnison, Colorado
Gunnison is a home rule municipality that is the county seat and the most populous municipality of Gunnison County, Colorado. The city population was 6,560 at the 2020 United States Census. Gunnison was named in honor of John W. Gunnison, a United States Army officer who surveyed for a transcontinental railroad in 1853. History The City of Gunnison got its name from the first known European-American explorer of the area, John W. Gunnison. He was searching for a route for the transcontinental railroad in 1853 and only stayed for three days before traveling west to Utah. Gunnison saw its first population increase in the 1870s, due to the mining surge throughout the state. The railroad arrived soon after in 1880 to appreciative miners, ranchers, and farmers. In the early 1800s, the groups moving into the Gunnison area were mainly fur trappers and mountain men, trying to make a living for themselves in the rocky mountain terrain. But a drop in fur prices in the 1840s essenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gunnison River
The Gunnison River is located in western Colorado, United States and is one of the largest tributaries of the Colorado River. Description The river flows east to west and has a drainage area of according to the USGS. The drainage basin of the Gunnison collects water from different habitats, such as forests and alpine meadows, located the along Continental Divide. As the river flows westward, it carves through the San Juan Mountains. It flows into the Colorado River at Grand Junction. The Gunnison River Basin is popular for recreational activities such as fishing, rafting, boating, camping, hiking, and rock climbing. Contamination of the Gunnison River with selenium and mercury results from irrigation of high-selenium soils derived from the Mancos Shale and from mineral mining. The region surrounding the Gunnison River is part of the Colorado Mineral Belt. Contamination of the Gunnison River with selenium and mercury is a conservation concern for the bonytail chub, C ...

Pratt Truss
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 ...

American Bridge Company
The American Bridge Company is a heavy/civil construction firm that specializes in building and renovating bridges and other large, complex structures. Founded in 1900, the company is headquartered in Coraopolis, Pennsylvania, a suburb of Pittsburgh. The firm has built many bridges in the U.S. and elsewhere; the Historic American Engineering Record notes at least 81. American Bridge has also built or helped build the Willis Tower, the Empire State Building, the Chrysler Building, launch pads, resorts, and more. During World War II, it produced tank landing ships (LSTs) for the United States Navy. In 2020, American Bridge Company was acquired by Southland Holdings LLC. History American Bridge Company was founded in April 1900, when J.P. Morgan & Co. led a consolidation of 28 of the largest U.S. steel fabricators and constructors. The company's roots extend to the late 1860s, when one of the consolidated firms, Keystone Bridge Company, built the Eads Bridge at St. Louis, ...

Bridges On The National Register Of Historic Places In Colorado
A bridge is a structure built to Span (engineering), 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 ...
