Mill Creek Bridge (Clarence, Iowa)
Mill Creek Bridge is a historic structure located in a rural area north of Clarence, Iowa, United States.The Cedar Bluff Bridge over the Cedar River was the first all-iron span built in Cedar County in 1877. Four more iron spans were built later that year, as were several others over the years before this bridge was completed in 1889. It is the only one of those bridges left, and one of the oldest pony truss bridges in the state of Iowa. Citizens in Dayton Township petitioned the Cedar County Board of Supervisors in June 1888 for the bridge over Mill Creek. The supervisors contracted with Ward and Keepers of Clinton, Iowa to design and build the bridge. The span was built on concrete-filled iron cylinder piers, with timber stringer approach spans. Over the years sub-structural alterations have been made to the bridge. It has subsequently been abandoned and its deck is in a deteriorating condition. The bridge was listed on the National Register of Historic Places The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pony 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 the ...

Cedar River (Iowa River)
The Cedar River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed May 13, 2011 river in Minnesota and Iowa. It is a tributary of the Iowa River, which flows to the Mississippi River. The Cedar River takes its name from the red cedar (''Juniperus virginiana'') trees growing there, and was originally called the Red Cedar River by the Meskwaki. The first Mississippi steamboat reached Cedar Rapids, Iowa in 1844, and during the next decade, the Red Cedar (as it was still called) was an important commercial waterway. The surrounding region is known officially as the Cedar River Valley, though it is more commonly referred to simply as the Cedar Valley. The stream is young geologically, and only in places where the glacial material has been removed is the underlying bedrock exposed. Geography The headwaters of the Cedar River are located in Dodge County, Minnesota, consisting of a west fork and middle fork approximately ...

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 and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Completed In 1889
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Road Bridges On The National Register Of Historic Places In Iowa
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 ...
