U.S. Route 50N (Ohio)
State Route 550 (SR 550) is an east–west state highway in the southeastern portion of the U.S. state of Ohio. The western terminus of SR 550 is at an interchange with U.S. Route 33 (US 33) just north of the city limits of Athens, immediately south of the southern terminus of SR 13. The eastern terminus of SR 550 is at an intersection with SR 7 just west of Marietta. Route description Along its way, SR 550 passes through the counties of Athens and Washington. There is no section of the highway that is incorporated within the National Highway System. History The route connecting Athens and Marietta has been a state highway since the system's creation in Ohio in the 1910s. Prior to 1922, the route was known as SR 157. Between 1923 and 1929, the route became the southernmost part of SR 26. In 1929, the SR 26 designation was removed and replaced by a part of U.S. Route 50N, a divided route from US 50. This route ran from Athens at US 50 east to Marietta. It then continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio Department Of Transportation
The Ohio Department of Transportation (ODOT; ) is the administrative department of the Ohio state government responsible for developing and maintaining all state and U.S. roadways outside of municipalities and all Interstates except the Ohio Turnpike. In addition to highways, the department also helps develop public transportation and public aviation programs. ODOT is headquartered in Columbus, Ohio. Formerly, under the direction of Michael Massa, ODOT initiated a series of interstate-based Travel Information Centers, which were later transferred to local sectors. The Director of Transportation is part of the Governor's Cabinet. ODOT has divided the state into 12 regional districts to facilitate development. Each district is responsible for the planning, design, construction, and maintenance of the state and federal highways in its region. The department employs over 6,000 people and has an annual budget approaching $3 billion. It celebrated its 100th anniversary in 2005 and ...

Concurrency (road)
A concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers. When two roadways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap, coincidence, duplex (two concurrent routes), triplex (three concurrent routes), multiplex (any number of concurrent routes), dual routing or triple routing. Concurrent numbering can become very common in jurisdictions that allow it. Where multiple routes must pass between a single mountain crossing or over a bridge, or through a major city, it is often economically and practically advantageous for them all to be accommodated on a single physical roadway. In some jurisdictions, however, concurrent numbering is avoided by posting only one route number on highway signs; these routes disappear at the start of the concurrency and reappear when it ends. However, any route that becomes unsigned in the middle of the concurren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation In Athens County, Ohio
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Highways In Ohio
The Ohio Department of Transportation (ODOT) is responsible for the establishment and classification of a state highway network which includes interstate highways, U.S. highways, and state routes. As with other states, U.S. and Interstate highways are classified as state routes in Ohio. There are no state routes which duplicate an existing U.S. or Interstate highway in Ohio. Ohio distinguishes between "state routes", which are all the routes on ODOT's system, and "state highways", which are the roads on the state route system which ODOT maintains, i.e. those outside municipalities, with a special provision for Interstate Highways. Besides the state highway network, there are various county and township road networks within the state. History The Ohio Inter-County Highways were created on June 9, 1911, with the passage of the McGuire Bill (Senate Bill 165, 79th Ohio General Assembly). Main Market Roads, the most important of the system, were defined on April 15, 1913. In 192 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hi Carpenter Memorial Bridge
The Hi Carpenter Memorial Bridge is a cantilever bridge over the Ohio River between Newport, Ohio and St. Marys, West Virginia. It carries Ohio State Route 807 (SR 807) and West Virginia Route 807 (WV 807) and serves to connect WV 2 with OH 7. Description The Hi Carpenter Memorial Bridge begins immediately to the north of the road's T intersection with WV 2 (Pleasants Highway) just west of the city of St. Marys in Pleasants County, West Virginia. WV 2 heads southwest toward Parkersburg and northeast into St. Marys, where it provides access to WV 16. The four-lane cantilever truss bridge crosses over CSX's Ohio River Subdivision rail line before crossing the Ohio River. The bridge crosses the West Virginia–Ohio state line near the Ohio bank of the river. The structure ends immediately after crossing over OH 7 just east of the unincorporated village of Newport in Newport Township in Washington County, Ohio. From the north end of the bridge, the northern approach road has a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Bridge
The Silver Bridge was an eyebar-chain suspension bridge built in 1928 and named for the color of its aluminum paint. The bridge carried U.S. Route 35 over the Ohio River, connecting Point Pleasant, West Virginia, and Gallipolis, Ohio. On December 15, 1967, the Silver Bridge collapsed under the weight of rush-hour traffic, resulting in the deaths of 46 people. Two of the victims were never found. Investigation of the wreckage pointed to the cause of the collapse being the failure of a single eyebar in a suspension chain, due to a small defect deep. Analysis showed that the bridge was carrying much heavier loads than it had been designed for and had been poorly maintained. The collapsed bridge was replaced by the Silver Memorial Bridge, which was completed in 1969. History of eyebar-chain bridge construction At the time of the Silver Bridge construction, eyebar bridges had been built for about 100 years. Such bridges had usually been constructed from redundant bar links, using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be co ...

Eyebar
In structural engineering and construction, an eyebar is a straight bar, usually of metal, with a hole ("eye") at each end for fixing to other components. Eyebars are used in structures such as bridges, in settings in which only tension, and never compression, is applied. Also referred to as "pin - and eyebar construction" in instances where pins are being used. Structure A closed eyebar will typically have a rectangular cross section of constant thickness throughout its length and a constant width for all but the ends. The ends will transition to a wider part that is terminated by a rounded end. In the center of this end will be a hole which will receive a cylindrical pin, which may have provision to accept one or more nuts or bolts. If of round cross section the bar will typically be end-forged to create a head, which is then flatted by additional forging. The head may then be machined to a precise thickness and flatness. An alternative method for using round bar is to form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
