Ironton–Russell Bridge
The Ironton–Russell Bridge can refer to either one of two bridges that carry/carried traffic along the Ohio River between Ironton, Ohio and Russell, Kentucky in the United States. The original blue cantilever Ironton–Russell Bridge, opened in 1922 and closed in 2016, carried two lanes of traffic and a narrow sidewalk. The new white cable-stayed bridge, officially named the Oakley C. Collins Memorial Bridge, has two lanes of traffic without a dedicated sidewalk and opened on November 23, 2016. Original bridge The original purple cantilever Ironton–Russell Bridge opened in 1922. It carried two lanes of traffic and a narrow sidewalk. The bridge was retrofitted in the 1970s with strengthening beams and plates. Later inspection of the bridge revealed that these plates had been welded to the bridge using techniques that violated the bridge welding codes and reduced the fatigue strength of primary load members. As a result of these findings, ODOT added reinforcements to so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio River
The Ohio River () is a river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing in a southwesterly direction from Pittsburgh, Pennsylvania, to its river mouth, mouth on the Mississippi River in Cairo, Illinois, Cairo, Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the Mississippi River. It is also the sixth oldest river on the North American continent. The river flows through or along the border of six U.S. state, states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern United States. It is the source of drinking water for five million people. The river became a primary transportation route for pioneers during the westward expansion of the early U.S. The lower Ohio River just below Louisville was obstructed by rapids known as the Falls of the Oh ...

Ohio House Of Representatives
The Ohio House of Representatives is the lower house of the Ohio General Assembly, the state legislature of the U.S. state of Ohio; the other house of the bicameral legislature being the Ohio Senate. The House of Representatives first met in Chillicothe on March 3, 1803, under the later superseded state constitution of that year. In 1816, the capital was moved to Columbus, where it is located today. Members are limited to four successive two-year elected terms (terms are considered successive if they are separated by less than four years). Time served by appointment to fill out another representative's uncompleted term does not count against the term limit. There are 99 members in the house, elected from single-member districts. Every even-numbered year, all the seats are up for re-election. Composition Leadership Members of the 136th House of Representatives ↑: Member was originally appointed to the seat. Officials Speaker of the House The Speaker of the Hou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridges Over The Ohio River
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path 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, 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 in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the word ''bridge' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bridges In Ohio
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, 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 ...

OH-253
Hydroxide is a diatomic anion with chemical formula OH−. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base, a ligand, a nucleophile, and a catalyst. The hydroxide ion forms salts, some of which dissociate in aqueous solution, liberating solvated hydroxide ions. Sodium hydroxide is a multi-million-ton per annum commodity chemical. The corresponding electrically neutral compound HO• is the hydroxyl radical. The corresponding covalently bound group of atoms is the hydroxy group. Both the hydroxide ion and hydroxy group are nucleophiles and can act as catalysts in organic chemistry. Many inorganic substances which bear the word ''hydroxide'' in their names are not ionic compounds of the hydroxide ion, but covalent compounds which contain hydroxy groups. Hydroxide ion The hydroxide ion is naturally produced from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
