Dauphin Island Bridge
The Dauphin Island Bridge, formally the Gordon Persons Bridge, carries a , two-lane section of Alabama State Route 193 from mainland Mobile County, Alabama across the Gulf Intracoastal Waterway to Dauphin Island. The natural channel followed by the Gulf Intracoastal Waterway at this location is Pass Aux Herons. The bridge separates the Mississippi Sound on the west from Mobile Bay on the east. It was named in honor of Seth Gordon Persons, the 46th governor of Alabama. History The original bridge opened on July 2, 1955. It was destroyed by Hurricane Frederic in 1979 and was replaced by a fixed precast concrete segmental bridge A segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constru ... in 1982. The central main span was the first use of a span on a precast concrete segmental bridge. ...

Alabama State Route 193
State Route 193 (SR 193) is a route that serves as the primary travel route into Dauphin Island through southern Mobile County. South of its intersection with Laurendine Road, SR 193 is known as Dauphin Island Parkway, with the northern half of Dauphin Island Parkway routed along SR 163. The northern portion of SR 193 is known as Range Line Road. Route description The southern terminus of SR 193 is located at the western terminus of the Fort Morgan ferry in eastern Dauphin Island. From this point, the route travels in a westerly direction before turning to the north off the island across the Gordon Persons Bridge spanning the Mississippi Sound. From this point, the route travels across Mon Louis Island, over Fowl River, and continues onward in a northerly direction, where it has a full cloverleaf interchange with I-10 at exit 17 before reaching its northern terminus at US 90 U.S. Route 90 or U.S. Highway 90 (US 90) is an east–west major United States highway in the ...

Precast Concrete
Precast concrete is a construction product produced by casting concrete in a reusable molding (process), mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beam (structure), beams, and wall panels for tilt up construction. In contrast, cast-in-place concrete is poured into site-specific forms and cured on site. Recently lightweight expanded polystyrene foam is being used as the cores of precast wall panels, saving weight and increasing thermal insulation. Precast stone is distinguished from precast concrete by the finer construction aggregate, aggregate used in the mixture, so the result approaches the natural product. Overview Precast concrete is employed in both interior and exterior applications, from highway, bridge, and hi-rise projects to tilt-up building construction. By producing precast concrete in a controlled environment (typically referred to as a precast plant), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bridges In Alabama
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 ...

Bridges Completed In 1982
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.

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Segmental Bridge
A segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then transported to their final location for placement in the full structure). These bridges are very economical for long spans (more than ), especially when access to the construction site is restricted. They are also chosen for their aesthetic appeal. History The first cantilevered segmental cast-in-place concrete bridge, built in 1930, was across Rio do Peixe in the state of Santa Catarina of Brazil. It was followed in 1951 by the prestressed concrete bridge across the Lahn River in , the first of many cantilevered bridges designed by . The first prestressed concrete bridge, assembled by several precast elements, was the across the river Marne in F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Frederic
Hurricane Frederic was an intense and damaging tropical cyclone that carved a path of destruction from the Lesser Antilles to Quebec, in particular devastating areas of the United States Gulf Coast. Though only five were killed directly, the US$1.77 billion (equivalent to $ billion in ) in damage accrued by Frederic made it the Atlantic basin's costliest tropical cyclone on record at the time. Prior to its final landfall, the threat that Frederic imposed on areas of the U.S. Gulf Coast triggered a mass exodus from the region larger than any other evacuation in the past. While the storm primarily impacted the U.S. states of Mississippi and Alabama, lesser effects were felt throughout the Greater and Lesser Antilles, as well as inland North America. Frederic was the thirteenth tropical cyclone, sixth named storm, third hurricane, and second major hurricane of the 1979 Atlantic hurricane season. It developed from a tropical depression south of the Cape Verde Islands on Augus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Intracoastal Waterway
The Gulf Intracoastal Waterway is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately from Carrabelle, Florida, to Brownsville, Texas. The waterway provides a channel with a controlling depth of , designed primarily for barge transportation. Although the U.S. government proposals for such a waterway were made in the early 19th century, the Gulf Intracoastal Waterway was not completed until 1949. EHL & WHL mileages Locations along the Gulf Intracoastal Waterway are defined in terms of statute miles (as opposed to nautical miles, in which most marine routes are measured) east and west of Harvey Lock, a navigation lock in the New Orleans area located at . The Hathaway Bridge in Panama City, Florida, for example, is at mile 284.6 EHL (East of Harvey Lock). The Queen Isabella Causeway Bridge at South Padre Island is at mile 665.1 WHL (West of Harvey Lock). Connecting waterways Th ...

Gordon Persons
Seth Gordon Persons (February 5, 1902 – May 29, 1965) was an American Democratic politician who was the 43rd Governor of Alabama from 1951 to 1955. He was born and died in Montgomery, Alabama. The Dauphin Island Bridge south of Mobile is formally named for him. The Gordon Persons Building is a six floor, 60,000 square foot state government office building in Montgomery. Persons studied electrical engineering in college, leading to a very successful business running electrical lines in rural Alabama (benefiting from Rural Electrification Administration contracts); in addition to financial gain, he also won considerable popularity. When running for office in 1950, Persons gained notoriety by touring the state in a helicopter (prompting one opponent to dub him "the man from Mars"). He won the Democratic nomination by defeating a crowded field that included former governor Chauncey Sparks. In office, his notable accomplishments included abolishing flogging in Alabama's pris ...

Mobile Bay
Mobile Bay ( ) is a shallow inlet of the Gulf of Mexico, lying within the state of Alabama in the United States. Its mouth is formed by the Fort Morgan Peninsula on the eastern side and Dauphin Island, a barrier island on the western side. The Mobile River and Tensaw River empty into the northern end of the bay, making it an estuary. Several smaller rivers also empty into the bay: Dog River, Deer River, and Fowl River on the western side of the bay, and Fish River on the eastern side. Mobile Bay is the fourth largest estuary in the United States with a discharge of of water per second. Annually, and often several times during the summer months, the fish and crustaceans will swarm the shallow coastline and shore of the bay. This event, appropriately named a jubilee, draws a large crowd because of the abundance of fresh, easily caught seafood. Mobile Bay is in area. It is long by a maximum width of . The deepest areas of the bay are located within the shipping channel, someti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
