Hump Day History
The Gateway Arch in St. Louis, Missouri was completed on this day, 1965. It is a 630 feet catenary curve of stainless steel, designed by Eero Saarinen. It was erected to commemorate Thomas Jefferson's Louisiana Purchase and St. Louis' central role in the westward expansion that followed. The lift to the top deck is a custom-engineered tram that combines the principles of a traditional elevator and a Ferris wheel. Capsule cars are linked by a chain which rotate individually to keep the passengers upright. I saw a documentary about a tornado that went through the city in 2025, with winds up to 150 mph. The arch held, and though guests up top got some motion sickness, as it swayed up to 18 inches side to side, there were no injuries and no damage reported.
