Claude Allen Porter Turner
Claude Allen Porter Turner (July 4, 1869 – January 10, 1955) was an American structural engineer who designed a number of buildings and bridges, particularly in the midwestern U.S. states of Iowa, Minnesota, and Wisconsin. Turner was born in Lincoln, Rhode Island, and attended Lehigh University's school of engineering in Bethlehem, Pennsylvania, graduating in 1890. He worked for several companies in the eastern United States before moving to Minneapolis, Minnesota, in 1897. He formed his own company in 1901 and received a patent in 1908 for an innovative flat-slab support system, known as the Turner System or the Spiral Mushroom System, using reinforced concrete, although this patent was invalidated in 1915 and 1916 in favor of similar patents filed by American engineer O.W. Norcross. Turner's patent, however, was licensed to overseas designers including Hugh Ralston Crawford in Australia. Turner would eventually receive 30 patents related to reinforced concrete. He died ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soo Line High Bridge
The Soo Line High Bridge, also known as the Arcola High Bridge, is a steel deck arch bridge over the St. Croix River between Stillwater, Minnesota and Somerset, Wisconsin, United States. It was designed by structural engineer C.A.P. Turner and built by the American Bridge Company from 1910 to 1911. The bridge was listed on the National Register of Historic Places in 1977 for its national significance in the themes of engineering and transportation. It was nominated for its exceptional dimensions, beauty, innovative engineering techniques, and importance to transportation between Minnesota and Wisconsin. History The bridge was the second bridge on a Wisconsin Central Railway line that connected Chippewa Falls, Wisconsin, with Minneapolis, Minnesota. The line was originally built in 1884. The crossing of the St. Croix River was difficult for the railway, since the original bridge across the river was very low and trains had to contend with steep grades on both sides of the rive ...

Concrete Pioneers
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical properties ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transporter Bridge
A transporter bridge, also known as a ferry bridge or aerial transfer bridge, is a type of movable bridge that carries a segment of roadway across a river. The gondola is slung from a tall span by wires or a metal frame. The design has been used to cross navigable rivers or other bodies of water, where there is a requirement for ship traffic to be able to pass. This has been a rare type of bridge, with fewer than two dozen built. There are just twelve that continue to be used today. History The concept of the transporter bridge was invented in 1873 by Charles Smith (1844–1882), the manager of an engine works in Hartlepool, England. He called it a "bridge ferry" and unsuccessfully presented his ideas to councils in Hartlepool, Middlesbrough, and Glasgow. The first transporter bridge, Vizcaya Bridge was built between Las Arenas and Portugalete, Spain, in 1893. The design from Alberto Palacio inspired others to attempt similar structures. The idea came about in locations wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aerial Lift Bridge
The Aerial Lift Bridge, earlier known as the Aerial Bridge or Aerial Ferry Bridge, is a landmark in the port city of Duluth, Minnesota. The span began life in 1905 as the United States' first transporter bridge: Only one other was ever constructed in the country, Sky Ride in Chicago. The span was converted in 1929–1930 to a vertical-lift bridge, also rather uncommon, although there are six such bridges along Ontario's Welland Canal. It remains in operation. The bridge is owned and operated by the City of Duluth. The bridge was added to the National Register of Historic Places on May 22, 1973. The United States Army Corps of Engineers maintains a nearby maritime museum. Bridge history The bridge spans the Duluth Ship Canal, which was put through the miles-long Spit (landform), sand spit named Minnesota Point – commonly called Park Point by locals – in 1870–1871.
