Boring Test Tunnel
The Boring Test Tunnel is a tunnel in Hawthorne, California for testing hyperloop and loop-based transportation. It was completed by The Boring Company in late 2018. The single-bore tunnel was constructed during 2017 and 2018 using a diameter tunnel boring machine, giving a finished internal diameter. Route Most of the route runs outside and set back from the perimeter of Hawthorne Municipal Airport, with a very short section under the corner of the airport fence, without going under the runway. The tunnel starts between the Dominguez Channel storm drain and Crenshaw Boulevard at an entrance pit constructed on parking lot land owned by SpaceX. A short straight section heading northwards is followed by a curve westwards under West 120th Street, then a long straight tunnel, a slight curve and a final short straight to the Exit Shaft. The midpoint of the tunnel is planned to connect with a very short northwards spur to a small car parking system-style car elevator leading u ...

Road Tunnels In California
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", wh ...

Transportation Buildings And Structures In Los Angeles
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 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnels In Los Angeles
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guided Busway
Guided buses are buses capable of being steered by external means, usually on a dedicated track or roll way that excludes other traffic, permitting the maintenance of schedules even during rush hours. Unlike trolleybuses or rubber-tired trams, for part of their routes guided buses are able to share road space with general traffic along conventional roads, or with conventional buses on standard bus lanes. Guidance systems can be physical, such as kerbs or guide bars, or remote, such as optical or radio guidance. Guided buses may be articulated, allowing more passengers, but not as many as light rail or trams that do not also freely navigate public roads. History Precursors The kerb-guided bus (KGB) guidance mechanism is a development of the early flangeways, pre-dating railways. The Gloucester and Cheltenham Tramroad of 1809 therefore has a claim to be the earliest guided busway. There were earlier flangeways, but they did not carry passengers. Modern examples There are ...

Structural Encroachment
A structural encroachment is a concept in real property law, in which a piece of real property projects from one property over or under the property line of another landowner's premises. The actual structure that encroaches might be a tree, bush, bay window, stairway, steps, stoop, garage, leaning fence, part of a building, or other fixture. Some attorneys classify it as a type of easement, related to an ''easement in gross'', while some scholars classify such as one type of encroachment. Creation When a structural encroachment is created intentionally, it is basically an easement in gross, and may be done by a permit to a government authority. A zoning law may also restrict an intentional structural encroachment. A structural encroachment may also be created by necessity, by accident, or by prescription. Other uses * In some medical contexts, a lump protruding into a blood vessel is described as a structural encroachment. * In some ecological contexts, the process of a peat ...

Easement
An easement is a nonpossessory right to use and/or enter onto the real property of another without possessing it. It is "best typified in the right of way which one landowner, A, may enjoy over the land of another, B". An easement is a property right and type of incorporeal property in itself at common law in most jurisdictions. An easement is similar to real covenants and equitable servitudes. In the United States, the Restatement (Third) of Property takes steps to merge these concepts as servitudes. Easements are helpful for providing access across two or more pieces of property, allowing individuals to access other properties or a resource, for example to fish in a privately owned pond or to have access to a public beach. The rights of an easement holder vary substantially among jurisdictions. Types Historically, common law courts would enforce only four types of easement: * Right-of-way (easements of way) * Easements of support (pertaining to excavations) * Easemen ...

Car Elevator
A car elevator or vehicle elevator is an elevator designed for the vertical transportation of vehicles. Car elevators are used to vertically transport vehicles inside buildings. The objective of these lifts is to increase the number of vehicles that can be parked in parking lots and parking garages. Where real estate is costly, these car parking systems can reduce overall costs by using less land to park the same number of cars. Vehicle lifts, which lift a car at its center of gravity, are used in garages and repair shops and are designed to allow access to a car's undercarriage for repair. Examples American politician and former presidential candidate Mitt Romney included a car elevator in his 2008 proposal for rebuilding his beach house in La Jolla, San Diego. The elevator is intended to transport cars between floors in a planned split-level, four-vehicle garage. Romney received final approval for the project in October 2013, after an appeal against San Diego's approval o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West 120th Street
West or Occident is one of the four cardinal directions or points of the compass. It is the opposite direction from east and is the direction in which the Sun sets on the Earth. Etymology The word "west" is a Germanic word passed into some Romance languages (''ouest'' in French, ''oest'' in Catalan, ''ovest'' in Italian, ''oeste'' in Spanish and Portuguese). As in other languages, the word formation stems from the fact that west is the direction of the setting sun in the evening: 'west' derives from the Indo-European root ''*wes'' reduced from ''*wes-pero'' 'evening, night', cognate with Ancient Greek ἕσπερος hesperos 'evening; evening star; western' and Latin vesper 'evening; west'. Examples of the same formation in other languages include Latin occidens 'west' from occidō 'to go down, to set' and Hebrew מַעֲרָב maarav 'west' from עֶרֶב erev 'evening'. Navigation To go west using a compass for navigation (in a place where magnetic north is the same dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
