C.A.P. 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 connecting 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 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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minnesota Historical Society
The Minnesota Historical Society (MNHS) is a nonprofit educational and cultural institution dedicated to preserving the history of the U.S. state of Minnesota. It was founded by the territorial legislature in 1849, almost a decade before statehood. The Society is named in the Minnesota Constitution. It is headquartered in the Minnesota History Center in downtown Saint Paul. Although its focus is on Minnesota history it is not constrained by it.

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, including one converted into a lift bridge and one designed as, but not yet operating as, a transporter bridge. 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 de ... [...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 – and continues to operate today. The bridge was added to the National Register of Historic Places on May 22, 1973. The bridge is owned and operated by the City of Duluth. 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 sand spit named Minnesota Point – commonly called Park Point by locals – in 1870–1871. The natural mouth of the Saint Louis River is about farther southeast, and is split between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
