Description: From the longest bridge in the world, to unbelievable superstructures, these are some of the BIGGEST Engineering Projects Ever ! HEY YOU ! There are more awesome videos being made every week, like and subscribe to World Unearthed so you don't miss a beat ! 7. The Interstate Highway System | USA On June 29, 1956, President Dwight D. Eisenhower signed the National Interstate and Defense Highways Act. The bill authorized federal spending of $25 billion, the equivalent of $250 billion today, to build 41,000 miles of interstate highways. It was at the time the biggest American public works project. The project’s estimated completion time was only 10 years. In reality, it took at least 35 years. There’s some arguments over when “it was finally completed” since very small sections of highways like the I-90 between New Jersey and Pennsylvania were not completed until 2018. So did it take 60 years to complete ? stuff like that. In total, the Interstate Highway System stretches 47,622 miles, with the longest being the I-90, a 3,085.3 mile highway going from Seattle to Boston. How much is 47,622 miles ? Enough to loop around the equator twice The shortest part of the highway system is the 17.6 mile I-97, connecting Baltimore to Annapolis. It is estimated that the travel time between San Francisco to Pennsylvania was cut down from two months to five days, and even though the total cost of the system is around 250 billion, its believed that it has returned $6 for every $1 spent. Do you think society can undertake such a monumental country spanning project today ? I’m not so sure. 6. Large Hadron Collider | France/Switzerland The Large Hadron Collider (LHC), large refers to its size; hadron because it accelerates protons or ions which belong to the group of particles called hadrons;and collider because the particles form two beams traveling in opposite directions, which are made to collide at four points around the machine. The LHC is the most powerful particle accelerator ever built. The accelerator sits in a tunnel as deep as 574ft underground at CERN, the European Organization for Nuclear Research, on the Franco-Swiss border near Geneva, Switzerland. The LHC consists of a 17mi ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. The first particle collisions were achieved in 2010, and since then, it has helped tremendously in the research of particle physics and might provide answers for some of science’s most interesting unresolved questions. In 2018, the collider was shut down for further upgrades, it reopened in May 2021…. I wonder what new information they will find out ! 5. TEN-T Core Network | Europe Most road networks in the EU were developed from a national viewpoint. The aim of TEN is to build a transport network that would facilitate the flow of goods and people between EU countries. The Trans-European Transport Network is a planned network of roads, railways, airports and water infrastructure around all EU member countries. This project has been in the works, or at least in the minds of politicians since 1990. TEN-T guidelines were officially adopted in 1996, and in 2017, it was decided that the network would be extended into Eastern Europe. WOW, very nice. In 2019, the furthest eastern expansion reached Armenia. I’m not sure how current this information is, but the estimated total length of roadways and highways built under TEN-T is 55,000 miles. Which as we learned, is a very very large number. 4. Maglev High Speed Rail Project | Japan Known as Chūō Shinkansen, this incredibly ambitious mega project aims to connect Tokyo City to Nagoya, and eventually Osaka. The line would operate at a maximum speed of 500 km/h and will connect Tokyo and Nagoya in 40 minutes, as well as Tokyo and Osaka in 67 minutes. Which would come out to train speeds of about 311 miles per hour. Tunnels will make up about 90% of the 286-kilometer (178-mile) line to Nagoya. This project is the culmination of Japanese maglev development that started in the 1970s under government funded projects. The government gave its blessing on the construction designs and work commenced in 2014. The total cost of the project is estimated at around 9 Trillion yen, or about 82 billion dollars. JR Central, the company behind the project, believes the line will begin commercial service between Tokyo and Nagoya in 2027, and the extra section to Osaka by 2037 3. Panama Canal | Panama 2.
