Don N. Holt Bridge
The Don N. Holt Bridge is a parallel chord, three-span continuous, modified Warren-type truss bridge that carries Interstate 526 (I-526) over the Cooper River between Charleston and North Charleston. It was built in 1992 by the South Carolina Department of Transportation and was designed by HNTB Corporation. The bridge provides a connection between the communities east of the Cooper River, including Mount Pleasant and Daniel Island, to North Charleston and I-26. It is part of a major hurricane evacuation route for the area. The Don Holt Bridge is adjacent to a Kapstone (formerly MeadWestvaco) paper mill. In the mid 1980s, prior to construction of the bridge, owners of the mill filed a lawsuit to stop the bridge because the bridge deck would be at the same height as smokestacks from the mill. In certain weather conditions, the smokestacks produce a fog which could blind drivers and place the mill at risk for lawsuits from drivers. The lawsuit was settled by mandating that ...

Deck (bridge)
A deck is the surface of a bridge. A structural element of its Superstructure#bridge, superstructure, it may be constructed of concrete, steel, grating, open grating, or wood. Sometimes the deck is covered by a track ballast, railroad bed and railroad track, track, asphalt concrete, or other form of pavement (material), pavement for ease of vehicle crossing. A concrete deck may be an integral part of the bridge structure (T-beam or double tee structure) or it may be supported with I-beams or steel girders. When a bridge deck is installed in a through truss, it is sometimes called a floor system. A suspended bridge deck will be suspended from the main structural elements on a suspension or arch bridge. On some bridges, such as a Tied-arch bridge, tied-arch or a Cable-stayed bridge, cable-stayed, the deck is a primary structural element, carrying tension or compression to support the span. A deck bridge is one in which the deck itself is the main structural element, itself carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Rail Transport
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

I-526
Interstate 526 (I-526) is a auxiliary route of I-26, providing a partial beltway around Charleston, South Carolina, in the United States. The route serves several purposes, firstly, as a bypass for through traffic on U.S. Route 17 (US 17) to avoid downtown Charleston, and, secondly, for traffic on I-26 bound for the coastal towns located north and south of Charleston. The route is not yet complete, as the western terminus it is planned for the route to be extended an additional . After the eastern terminus, the roadway continues as a short business route, known as Interstate 526 Business (I-526 Bus.). Route description I-526 begins at an incomplete interchange with US 17 (Savannah Highway) and South Carolina Highway 7 (SC 7, Sam Rittenberg Boulevard) in the West Ashley section of the city of Charleston, just north of the Stono River. The interchange includes a loop ramp from northbound US 17, a ramp from southbound US 17, and a half-di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Carolina General Assembly
The South Carolina General Assembly, also called the South Carolina Legislature, is the state legislature of the U.S. state of South Carolina. The legislature is bicameral and consists of the lower South Carolina House of Representatives and the upper South Carolina Senate. All together, the General Assembly consists of 170 members. The legislature convenes at the State House in Columbia. Prior to the 1964 federal ''Reynolds v. Sims'' decision by the U.S. Supreme Court, each county doubled as a legislative district, with each county electing one senator and at least one representative. Moreover, each county's General Assembly delegation also doubled as its county council, as the state constitution made no provision for local government. The "one man, one vote" provision of ''Reynolds v. Sims'' caused district lines to cross county lines, causing legislators to be on multiple county councils. This led to the passage of the Home Rule Act of 1975, which created county counc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Carolina House Of Representatives
The South Carolina House of Representatives is the lower house of the South Carolina General Assembly. It consists of 124 representatives elected to two-year terms at the same time as U.S. congressional elections. Unlike many legislatures, seating on the floor is not divided by party, but is arranged by county delegation – a legacy of the original apportionment of the chamber. Until 1964, each of South Carolina's counties was a legislative district, with the number of representatives determined by the county's population. It meets from the second week of January into May. History In Colonial times, there was a Commons House of Assembly. Qualifications and terms Representatives are considered part-time citizen legislators who serve two-year terms. Representatives are elected at-large by their district, and there are no term limits. Representatives must be 21 years of age before they are eligible to become a representative.
