Busk–Ivanhoe Tunnel
Busk–Ivanhoe Tunnel was a 9,394 ft (2,863 m) long railroad tunnel at an elevation of 10,953 ft (3,338 m) in Colorado. It was built by the Busk Tunnel Railway Company for the Colorado Midland Railroad in 1891 as a replacement for the Hagerman Tunnel at a lower, more direct route. The tunnel was briefly abandoned following Colorado Midland's 1897 bankruptcy, but returned to use a few years later."NEWS OF THE RAILROADS.; The Federal Receivership for the Colorado Midland Ended – Busk-Ivanhoe Tunnel Abandoned" (1897-11-02). ''The New York Times'': 11. It was converted to auto traffic in 1922 as the Carlton Tunnel, a toll tunnel carrying then- State Highway 104, closing in 1942 when the state discontinued maintenance of the road. The tunnel collapsed in 1945.John N. WinchesterA Historical View: Transmountain Development in Colorado, 2000; retrieved July, 2015. Starting in 1921, while it was still a highway tunnel, the tunnel was also used as a water diversio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado Midland
The Colorado Midland Railway , Railway Equipment and Publication CompanyThe Official Railway Equipment Register June 1917, p. 786 incorporated in 1883, was the first standard gauge railroad built over the Continental Divide in Colorado. It ran from Colorado Springs to Leadville and through the divide at Hagerman Pass to Glenwood Springs and Grand Junction. History John J. Hagerman gained control of the Colorado Midland Railway Company in June 1885. In September 1890, Hagerman sold the railroad to the Atchison, Topeka and Santa Fe Railway, which operated the railroad as a subsidiary and changed the name to the Colorado Midland Railroad. For a short time the railroad was consolidated with the Aspen Short Line (1893-1897). Following the Panic of 1893, the Santa Fe railroad failed and both it and the Colorado Midland went into receivership. During this time, a crash in the price of silver also led to economic decline in the mining towns served by the railway. After the c ...

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid drainage basin, watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the Mexico–United States border, international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven National parks of the United States, U.S. National Parks, the Colorado River and its tributaries are a v ...

Former Toll Roads In Colorado
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

Tunnels Completed In 1893
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 transport, 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 transport, rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sanitary sewer, sewers or aqueduct (watercourse), 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 crossi ...

Water Tunnels In The United States
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers a ...
