@california_history: The Tallest Building in the American West The tallest building in the entire western United States stands in downtown Los Angeles, and constructing it began by shattering a Guinness World Record. 🏙️ The Wilshire Grand Center rises 1,100 feet, making it the tallest building west of the Mississippi River. In February 2014, crews began pouring its foundation in a single, unbroken effort. For roughly 18 hours, more than 200 trucks delivered concrete from eight plants around the clock, ultimately placing about 82 million pounds of concrete in one continuous pour, creating an 18-foot-thick foundation anchored to bedrock. It set the world record for the largest continuous concrete pour at the time. The tower also broke from tradition at the top. For decades, LA skyscrapers were required to have flat roofs to allow helicopter rescues, but the Wilshire Grand earned an exemption thanks to advanced fire-safety technology, freeing architects to crown it with a dramatic sail-shaped glass top and glowing spire, wrapped in about 2.5 miles of LED lighting. Opened in 2017 after 40 months and 11,000 workers, it claims its title through that spire, even though the older U.S. Bank Tower's roof technically sits a bit higher.
