Pacheco Pass Tunnels
The Pacheco Pass Tunnels are a planned set of tunnels to carry California High-Speed Rail across the Diablo Range in the vicinity of Pacheco Pass east of Gilroy, California. The tunnels will constitute the first mountain crossing constructed as part of California High-Speed Rail, connecting the San Francisco Bay Area and Central Valley portions of the system. The tunnels are planned to consist of two diameter tunnels. At long the main tunnel is expected to become North America’s longest rail tunnel, surpassing the Mount Macdonald Tunnel in British Columbia. An additional rail tunnel is planned to be constructed to the west. The tunnels are expected to cost around $5 billion. The right-of-way runs parallel to the existing Pacheco Tunnel and Santa Clara Tunnel, two contiguous water tunnels connecting the San Luis Reservoir into Santa Clara County. History In 2004, two options were in consideration for the Diablo Range crossing: the Pacheco Pass option and a "direct" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnels
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two portals common at each end, though there may be access and ventilation openings at various points along the length. A pipeline differs significantly from 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.Salazar, Waneta.

Franciscan Assemblage
The Franciscan Complex or Franciscan Assemblage is a geologic term for a late Mesozoic terrane of heterogeneous rocks found throughout the California Coast Ranges, and particularly on the San Francisco Peninsula. It was named by geologist Andrew Lawson, who also named the San Andreas Fault that defines the western extent of the assemblage. The Franciscan Complex is dominated by greywacke sandstones, shales and conglomerates which have experienced low-grade metamorphism. Other important lithologies include chert, basalt, limestone, serpentinite, and high-pressure, low-temperature metabasites ( blueschists and eclogites) and meta-limestones. Fossils like radiolaria are found in chert beds of the Franciscan Complex. These fossils have been used to provide age constraints on the different terranes that constitute the Franciscan. The mining opportunities within the Franciscan are restricted to deposits of cinnabar and limestone. The outcrops of the formation have a very ...

Eminent Domain In The United States
In the United States, eminent domain is the power of a state or the federal government to take private property for public use while requiring just compensation to be given to the original owner. It can be legislatively delegated by the state to municipalities, government subdivisions, or even to private persons or corporations, when they are authorized to exercise the functions of public character. Property taken by eminent domain may be for government use or by delegation to third parties, who will devote it to public or civic use or, in some cases, to economic development. The most common uses are for government buildings and other facilities, public utilities, highways and railroads. However, it may also be taken for reasons of public safety, as in the case of Centralia, Pennsylvania, where land was taken due to an underground mine fire. Some jurisdictions require that the condemnor make an offer to purchase the subject property before resorting to the use of eminent domain. ...

Dumbarton Rail Bridge
The Dumbarton Rail Bridge lies just to the south of the Dumbarton road bridge. Built in 1910, the rail bridge was the first structure to span San Francisco Bay, shortening the rail route between Oakland and San Francisco by . The last freight train traveled over the bridge in 1982, and it has been proposed since 1991 to reactivate passenger train service (connecting Caltrain on the Peninsula with ACE, BART and the Capitol Corridor in the East Bay) to relieve traffic on the road bridges, though this would entail a complete replacement of the existing bridge. Part of the western timber trestle approach collapsed in a suspected arson fire in 1998. History The Dumbarton Rail Bridge (then known as the Dumbarton Point Bridge or, simply, Dumbarton Bridge; one of the major structures of the Dumbarton Cut-off rail line) was championed by E. H. Harriman. Prior to the completion of the Dumbarton Cut-off, transcontinental rail freight was offloaded at Oakland and ferried to San Francisc ...
