Federal Aid Highway Act Of 1956
The Federal-Aid Highway Act of 1956, also known as the National Interstate and Defense Highways Act, was enacted on June 29, 1956, when President Dwight D. Eisenhower signed the bill into law. With an original authorization of $25 billion for the construction of of the Interstate Highway System over a 10-year period, it was the largest public works project in American history through that time. The addition of the term "defense" in the act's title was for two reasons: First, some of the original cost was diverted from defense funds. Secondly, most U.S. Air Force bases have a direct link to the system. One of the stated purposes was to provide access in order to defend the United States during a conventional or nuclear war with the Soviet Union and its communist allies. All of these links were in the original plans, although some, such as Wright-Patterson Air Force Base were not connected up in the 1950s, but only somewhat later. The money for the Interstate Highway and Defen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades. Tetraethyl lead and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toll Highway
A toll road, also known as a turnpike or tollway, is a public or private road (almost always a controlled-access highway in the present day) for which a fee (or ''toll'') is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and maintenance. Toll roads have existed in some form since antiquity, with tolls levied on passing travelers on foot, wagon, or horseback; a practice that continued with the automobile, and many modern tollways charge fees for motor vehicles exclusively. The amount of the toll usually varies by vehicle type, weight, or number of axles, with freight trucks often charged higher rates than cars. Tolls are often collected at toll plazas, toll booths, toll houses, toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll has been paid. To cut costs and minimise time delay, ...

Invasion Of The United States
The concept of an invasion of the United States relates to military theory and doctrine which address the feasibility and practicality of a foreign power attacking and successfully invading the United States. The country has been physically invaded on several occasions—once during the War of 1812, once during the Mexican–American War, several times during the Mexican Border War, and three times during World War II, two of which were air attacks on American soil. During the Cold War, most of the US military strategy was geared towards repelling an attack by the Warsaw Pact against NATO allies in Europe. Early attacks The military history of the United States began with a foreign power on US soil: the British Army during the American Revolutionary War. After American independence, the next attack on American soil was during the War of 1812, also with Britain, the first and only time since the end of the Revolutionary War in which a foreign power occupied the American capital ( ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autobahn
The (; German plural ) is the federal controlled-access highway system in Germany. The official German term is (abbreviated ''BAB''), which translates as 'federal motorway'. The literal meaning of the word is 'Federal Auto(mobile) Track'. German are widely known for having no federally mandated general speed limit for some classes of vehicles. However, limits are posted and enforced in areas that are urbanised, substandard, accident-prone, or under construction. On speed-unrestricted stretches, an advisory speed limit () of applies. While driving faster is not illegal as such in the absence of a speed limit, it can cause an increased liability in the case of a collision (which mandatory auto insurance has to cover); courts have ruled that an "ideal driver" who is exempt from absolute liability for "inevitable" tort under the law would not exceed . A 2017 report by the Federal Road Research Institute reported that in 2015, 70.4% of the Autobahn network had only the advis ...

Gettysburg, Pennsylvania
Gettysburg (; non-locally ) is a borough and the county seat of Adams County in the U.S. state of Pennsylvania. The Battle of Gettysburg (1863) and President Abraham Lincoln's Gettysburg Address are named for this town.

White House
The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the president and his advisers. The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by British forces in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began ...

Lincoln Highway
The Lincoln Highway is the first transcontinental highway in the United States and one of the first highways designed expressly for automobiles. Conceived in 1912 by Indiana entrepreneur Carl G. Fisher, and formally dedicated October 31, 1913, the Lincoln Highway runs coast-to-coast from Times Square in New York City west to Lincoln Park in San Francisco, originally through 13 states: New York, New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Colorado, Wyoming, Utah, Nevada, and California. In 1915, the "Colorado Loop" was removed, and in 1928, a realignment relocated the Lincoln Highway through the northern tip of West Virginia. Thus, there are a total of 14 states, 128 counties, and more than 700 cities, towns and villages through which the highway passed at some time in its history. The first officially recorded length of the entire Lincoln Highway in 1913 was . Over the years, the road was improved and numerous realignments were made, See throughout, bu ...

Transcontinental Motor Convoy
The Transcontinental Motor Convoys were early 20th century vehicle convoys, including three US Army truck trains, that crossed the United States (one was coast-to-coast) to the west coast. The 1919 Motor Transport Corps convoy from Washington, D.C., to San Francisco used the incomplete Lincoln Highway. Background The United States' Good Roads Movement of the late 19th century began as increased use of bicycles required better surfaces over the existing wagon and carriage roads. The development of the automobile and their increased use resulted in the formation of the United States Good Roads Association and various individual cross-country trips by individual vehicles, followed by the first transcontinental trip by a convoy of vehicles. 1915 transcontinental film convoy The 1915 transcontinental film convoy was a four-month motor convoy beginning August 25 and ending at the Panama–Pacific International Exposition in San Francisco.
