Le Grand Bridge (1914)
The Le Grand Bridge is an abandoned concrete girder bridge built in 1914–1915. It is an early example of concrete-girder work by the Iowa State Highway Commission. History The LeGrand Bridge carried traffic over the Iowa River for more than fifty years. The bridge is a multiple-span reinforced concrete girder construction. This type of bridge construction was typical in Marshall County, Iowa since the Brockway Act of 1913. Marshall county supervisors contracted with Des Moines-based Capital City Construction Company to build the bridge, which was completed early in 1915. The county later rechanneled the river and rerouted the road. The LeGrand Bridge now stands abandoned over a backwater of the river.

Concrete Girder Bridge
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box. The term "girder" is often used interchangeably with "beam" in reference to bridge design. However, some authors define beam bridges slightly differently from girder bridges. A girder may be made of concrete or steel. Many shorter bridges, especially in rural areas where they may be exposed to water overtopping and corrosion, utilize concrete box girder. The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold. Due to the properties of the second moment of area, the height of a girder is the most significant factor to affect its load capacity. Longer spans, more traffic, or wider spacing ...

Iowa State Highway Commission
The Iowa Department of Transportation (Iowa DOT) is the government organization in the U.S. state of Iowa responsible for the organization, construction, and maintenance of the primary highway system. Located in Ames, Iowa, DOT is also responsible for licensing drivers and programming and planning for aviation, rail, and public transit. The organization was created in 1904 as the Iowa State Highway Commission, an extension of Iowa State College in Ames. In 1913, the commission was spun off from the college and became a government organization. In 1974, the highway commission was folded into a larger transportation department with other modes of transportation. Organization Transportation Commission The decision-making body of the Iowa DOT is the Iowa Transportation Commission. Seven people, of whom no more than four people can represent the same political party, make up the commission.

Le Grand Bridge (1896)
The Le Grand Bridge was a bridge north of Le Grand, Iowa, United States. It spanned the Iowa River for , with carrying traffic on a gravel road named Abbot Avenue. Since Abbott Avenue is the border between Marshall and Tama counties, the bridge is in two counties lengthwise. Many bridges span from one county to another, but few are lengthwise split. It necessitated a joint session of the two counties' Boards of Supervisors on June 29, 1896, to approve the project. The pinned Pratt through truss bridge was built in 1896 by the Marshalltown Bridge and Iron Works for $3,548. It was listed on the National Register of Historic Places in 1998. The bridge collapsed in the Iowa flood of 2008 Iowa () is a U.S. state, state in the Midwestern United States, Midwestern region of the United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River to the west.

Bridges Completed In 1914
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 ... [...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 ...

Concrete Bridges In The United States
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients.
