Board Information & Statistics

Board Description
Gateway Arch
The Gateway Arch is located on the banks of the Mississippi River. The stainless steel-plated arch is in the shape of an inverted, weighted catenary curve. In order to withstand strong winds and earthquakes, the top of the arch was designed to sway up to 18 inches.
The observation deck at the top is accessed by a passenger train which climbs the wall of the arch.
