The Gateway Arch was completed 60 years ago. Here’s a history of how it happened

Sixty years ago, a construction crew added the final section to the very top of the Gateway Arch. In recognition of its 60th anniversary, we talk with two local historians about the monument’s place in American history, its influence on international architecture and labor movements, and why the Arch is still considered a modern engineering marvel today. We also explore what existed on the riverfront before the monument was constructed.
