Alt Text Perspective 3D rendering of Gateway Arch National Park in Missouri. A soaring silver arch spans a visitor center and opens onto Luther Fly Smith Square and Old Courthouse. The deep blue Mississippi River runs across the bottom edge of the map. Extended Description Panels from two areas of the inner edge of the arch reveal the structure inside or show the visitor tram cars to the top of the arch. Starting close to the river and moving back in space, the Grand Staircase leads from the water’s edge up to grassy lawns around the arch. The location of the T-shaped, underground Visitor Center and Museum at the Gateway Arch are outlined with a white dashed line between the legs of the arch. An arrow pointing to the left foot of the arch is labeled South Exit, and an arrow pointing to the right foot is labeled North Exit. The Visitor Center Entrance is a semi-circular structure where visitors enter underground at the far end of the visitor center. The Luther Fly Smith Square stretches between the Visitor Center Entrance and Old Courthouse, which has columns at the entryway, a dome, and wings projecting from either end of the building. The Dred and Harriet Scott statue is just outside. A church labeled Old Cathedral is to the left between the Old Courthouse and the Gateway Arch. Paths and walkways wind around and through the grassy lawns. Two of these paths, each leading up either side of the Grand Staircase, are labeled Accessible Routes to the Arch. A path in the green to the right has text reading “To the North Gateway.” The other buildings around the courthouse and church are represented as transparent gray silhouettes.
