Bridge To Nowhere (San Gabriel Mountains)
The Bridge to Nowhere is an arch bridge that was built in 1936 north of Azusa, California, United States in the San Gabriel Mountains. It spans the East Fork of the San Gabriel River and was meant to be part of a road connecting the San Gabriel Valley with Wrightwood, California. History The East Fork Road was still under construction when it was washed out during the great flood of March 1–2, 1938. The East Fork Road project was abandoned as a result of the floods, leaving the bridge forever stranded in the middle of what is now the Sheep Mountain Wilderness. Parts of the old asphalt roadway can still be found along the East Fork Trail which leads to the bridge, and there are still a number of concrete slabs which formed the foundations of destroyed bridges to the west of the Bridge to Nowhere. Indeed, the sign along the trail 30 feet east of the John Seals Bridge which announces the start of the Sheep Mountain Wilderness is resting on the old roadbed. East Fork Trail The br ...

Concrete Bridges In California
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges In Los Angeles County, California
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. Etymology The ''Oxford English Dictionary'' traces the origin of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bungee Jumping
Bungee jumping (), also spelled bungy jumping, is an activity that involves a person jumping from a great height while connected to a large elastic cord. The launching pad is usually erected on a tall structure such as a building or crane, a bridge across a deep ravine, or on a natural geographic feature such as a cliff. It is also possible to jump from a type of aircraft that has the ability to hover above the ground, such as a hot-air-balloon or helicopter. The thrill comes from the free-falling and the rebound. When the person jumps, the cord stretches and the jumper flies upwards again as the cord recoils, and continues to oscillate up and down until all the kinetic energy is dissipated. Early tethered jumping The land diving ( Sa: ') of Pentecost Island in Vanuatu is an ancient ritual in which young men jump from tall wooden platforms with vines tied to their ankles as a test of their courage and passage into manhood.

Inholding
An inholding is privately owned land inside the boundary of a national park, national forest, state park, or similar publicly owned, protected area. In-holdings result from private ownership of lands predating the designation of the park or forest area, or the expansion of the park area to encompass the privately owned property. In the United States, the main causes of inholdings is that all of the Federal land-management agencies were formed over a century after the government sold and issued land grants to private citizens to fund the administration of the United States. When the park system was formed, many of these now-called "inholdings" had been in private ownership for generations and not available for sale when the park was formed. Over the last several decades, conservation groups have lobbied the United States Congress to acquire private residences especially within designated wilderness areas, either by direct purchase or via land exchange which trades the inho ...
