On October 28, 1965, a modern steel landmark opened in St. Louis: the Gateway Arch. For the last 56 years, the monument has stood as a shining example of what's possible with steel--and it's still the world's tallest arch today!
A recent dive into the AISC archives uncovered a treasure trove: Kodachrome slides (remember those?) from the construction of the Gateway Arch. Dim the lights and join us for a nostalgic glimpse back at the making of an American icon.
