Seven Mile Bridge
The Seven Mile Bridge is a bridge in the Florida Keys, in Monroe County, Florida, United States. It connects Knight's Key (part of the city of Marathon, Florida) in the Middle Keys to Little Duck Key in the Lower Keys. Among the longest bridges in existence when it was built, it is part of the Overseas Highway in the Keys, which is part of the U.S. Route 1. There are two bridges in this location. The modern bridge is open to vehicular traffic; the older one only to pedestrians and cyclists. The older bridge, originally known as the Knights Key-Pigeon Key-Moser Channel-Pacet Channel Bridge, was constructed from 1909 to 1912 under the direction of Henry Flagler and Clarence S. Coe as part of the Florida East Coast Railway's Key West Extension, also known as the Overseas Railroad. History After the railroad was damaged by the Labor Day Hurricane of 1935, the line was sold to the United States government, which refurbished Seven Mile Bridge for automobile use.

Moser Channel
Moser Channel is the deepest passage spanned by the Seven Mile Bridge and is one of four predominant passages in the Florida Keys which allow exchange of waters to the north and west of the Keys (including Florida Bay and the Gulf of Mexico) with the Atlantic waters of Hawk Channel and the Florida Reef The Florida Reef (also known as the Great Florida Reef, Florida reefs, Florida Reef Tract and Florida Keys Reef Tract) is the only living coral barrier reef in the continental United States. It is the third largest coral barrier reef system in ... to the south and east. Moser Channel has an orientation perpendicular to the bridge. The other three Keys passages important to the exchange of south Florida coastal waters are Long Key Channel, Channel 5, and Channel 2. {{Florida Keys Bodies of water of Monroe County, Florida Straits of Florida Florida Keys ...

Overseas Railroad
The Overseas Railroad (also known as Florida Overseas Railroad, the Overseas Extension, and Flagler's Folly) was an extension of the Florida East Coast Railway to Key West, Florida, Key West, a city located beyond the end of the Florida peninsula. Work on the line started in 1905 and it operated from 1912 to 1935, when it was partially destroyed by the 1935 Labor Day Hurricane, Labor Day Hurricane. Some of the remaining infrastructure was used for the Overseas Highway. Henry Flagler and the origin of the Florida East Coast Railway Henry Flagler (1830–1913) was a principal in Rockefeller, Andrews & Flagler and later a founder of Standard Oil during the Gilded Age in the United States. The wealthy Flagler took an interest in Florida while seeking a warmer climate for his ailing first wife in the late 1870s. Returning to Florida in 1881, he became the builder and developer of resort hotels and railroads along the east coast of Florida. Beginning with Jacksonville, Florida, St. A ...

Sunshine Skyway Bridge
The Bob Graham Sunshine Skyway Bridge, often referred to as the Sunshine Skyway Bridge or the Sunshine Skyway, consists of a pair of long beam bridges with a central cable-stayed bridge that spans Lower Tampa Bay to connect St. Petersburg, Florida to Terra Ceia. The current Sunshine Skyway opened in 1987 and is the second bridge of that name on the site. It was designed by the Figg & Muller Engineering Group and built by the American Bridge Company. The bridge is considered the flagship bridge of Florida and serves as a gateway to Tampa Bay. The four-lane bridge carries Interstate 275 and U.S. Route 19, passing through Pinellas County, Hillsborough County and Manatee County. It is a toll road, with a $1.50 toll assessed on two-axle vehicles traveling in either direction and collected via cash or the state's SunPass system. The original Sunshine Skyway was a two-lane beam bridge with a central truss bridge built directly to the west of the current structure. It was completed ...

Seven Mile Bridge Run
The Seven Mile Bridge run is an annual race held in the Florida Keys by the Marathon Runners Club. The race is run as a benefit for youth activities in Marathon, Florida. The event was first held in 1982 to commemorate the completion of the Florida Keys bridge rebuilding program. The bridge, one of the longest segmental bridges in the world, spans the channel between Knight's Key and Little Duck Key. It is one of the few races that takes place entirely over water, and actually covers a distance of - a little shorter than the name suggests. The local Sheriff's Department close the bridge between 6:45am and 9am, with the race kicking off at 7:30am. Runners therefore have up to 1 hour 30 minutes to traverse the bridge, and 'beat the bus' - if they can't keep up with the pace they are picked up by one of a small fleet of yellow school buses. A post-race party follows after the finishing runners are returned to the starting area by bus. Until 2012, entry to the race was via a post ...

Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when sub ...

Fishing Pier

The first seaside piers were built in England in the early 19th century. A pier is a raised structure that rises above a body of water and usually juts out from its shore, typically supported by piling, piles or column, pillars, and provides above-water access to offshore areas. Frequent pier uses include fishing, [oat docking and access for both passengers and cargo, and oceanside recreation. Bridges, buildings, and walkways may all be supported by architectural piers. Their open structure allows tides and currents to flow relatively unhindered, whereas the more solid foundations of a quay or the closely spaced piles of a wharf can act as a breakwater, and are consequently more liable to silting. Piers can range in size and complexity from a simple lightweight wooden structure to major structures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Donna
Hurricane Donna, known in Puerto Rico as Hurricane San Lorenzo, was the strongest hurricane of the 1960 Atlantic hurricane season, and caused severe damage to the Lesser Antilles, the Greater Antilles, and the East Coast of the United States, especially Florida, in August–September. The fifth tropical cyclone, third hurricane, and first major hurricane of the season, Donna developed south of Cape Verde on August 29, spawned by a tropical wave to which 63 deaths from a plane crash in Senegal were attributed. The depression strengthened into Tropical Storm Donna by the following day. Donna moved west-northwestward at roughly and by September 1, it reached hurricane status. Over the next three days, Donna deepened significantly and reached maximum sustained winds of 130 mph (210 km/h) on September 4. Thereafter, it maintained intensity as it struck the Lesser Antilles later that day. On Sint Maarten, the storm left a quarter of the island's populati ...

Pigeon Key
Pigeon Key is a small island containing the historic district of Pigeon Key, Florida. The island is home to 8 buildings on the National Register of Historic Places, some of which remain from its earliest incarnation as a work camp for the Florida East Coast Railway. Today these buildings serve a variety of purposes, ranging from housing for educational groups to administrative offices for the non-profit Pigeon Key Foundation. The former Assistant Bridge Tender's House has been converted into a small museum featuring artifacts and images from Pigeon Key's colorful past. It is located off the old Seven Mile Bridge, at approximately mile marker 45, west of Knight's Key, (city of Marathon in the middle Florida Keys) and just east of Moser Channel, which is the deepest section of the span. The island was originally known as "Cayo Paloma" (literally translated as "Pigeon Key") on many old Spanish charts - said to have been named for large flocks of white-crowned pigeons (''Colum ...

Intracoastal Waterway
The Intracoastal Waterway (ICW) is a inland waterway along the Atlantic and Gulf of Mexico coasts of the United States, running from Massachusetts southward along the Atlantic Seaboard and around the southern tip of Florida, then following the Gulf Coast to Brownsville, Texas. Some sections of the waterway consist of natural inlets, saltwater rivers, bays, and sounds, while others are artificial canals. It provides a navigable route along its length without many of the hazards of travel on the open sea. Context and early history Since the coastline represented the national border, and commerce of the time was chiefly by water, the fledgling United States government established a degree of national control over it. Inland transportation to supply the coasting trade at the time was less known and virtually undeveloped, but when new lands and their favorable river systems were added with the Northwest Territory in 1787, the Northwest Ordinance established a radically new and f ...

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 ...
