Gateway Arch

I’ve lived in St. Louis my whole life except for a short period that was spent studying abroad in college. I’ve traveled here and there. When I look out the plane or  car window and catch a glimpse of the Arch, I know I am almost home.

Standing at 630 feet tall, the Gateway Arch is the tallest stainless steel monument in the world. This famous symbol of St. Louis opened as monument to the westward expansion of the U.S. in 1967.

As with any structure, repairs and upgrades need to be made. We were contacted to provide the structural engineering services for the elector motor upgrade project at the Jefferson National Expansion Memorial Gateway Arch
