In the middle of downtown Chicago, a massive steel bridge stands permanently upright—rusted, silent, and seemingly useless. But the Kinzie Street Railroad Bridge wasn’t always a relic. Once, it was a triumph of early 20th-century engineering—built by the same mind behind the Golden Gate Bridge—and a key artery in Chicago’s freight empire.
This episode uncovers how the city that once moved America’s goods came to abandon one of its most advanced structures. From the dawn of Chicago’s railroad age to the twilight of its industrial might, discover how progress, pride, and preservation turned a working bridge into a monument suspended between eras.
