Gateway Arch

The public entrance is on the west side, facing Fourth Street and the Old Courthouse; the Arch’s legs are exits only. Everyone passes through a security checkpoint, so arrive early for a timed tram ticket. The tram is popular and NPS recommends booking ahead. There is no dedicated Arch parking lot; the operator points drivers to the Stadium East garage about two blocks away.

The tram climbs inside one leg in small capsules just five feet across, each seating five. The climb takes about four minutes, followed by a short stay on the observation deck and a three-minute descent. Allow roughly 45 to 60 minutes for the whole tram visit. The capsules feel tight, so skip the ride if enclosed spaces are uncomfortable.

Reaching the deck and returning means at least 96 steps across six flights, and visitors may have to stand for 30 to 60 minutes. The top is not wheelchair accessible, and there are no restrooms or benches there. The museum and paved grounds have accessible options, so you can still have a full visit without riding.

The narrow windows face downtown St. Louis on one side and the Mississippi on the other. On a clear day, the view can reach about 30 miles; haze or low fog can hide much of it. The openings are small for a reason: the 16 windows on each side are only 7 by 27 inches, sized to withstand the pressure when the top section was fitted.

For a ground photo, walk a little off center beneath the curve so the observation-deck windows show. The reflection ponds also catch the Arch and its sweep; you don’t need a long walk to get the classic view.

The six-gallery museum is free and traces St. Louis from its colonial beginnings in 1764 through its riverfront port, industrial growth and the building of the Arch. It includes Indigenous and Creole history alongside the city’s role in westward expansion, which gives the monument a fuller story than the pioneer theme alone. There is a café below with coffee, snacks and cafeteria food, plus public restrooms and a shop; no dependable signature menu item makes the café a reason to come by itself.

Finnish-American architect Eero Saarinen’s design won a 1947–48 competition that drew 172 entries. He chose an inverted catenary, the curve a hanging chain makes, to suggest a gateway. The monument’s stainless-steel skin covers a structure of welded steel triangles. Construction ran from 1963 to 1965.

Landscape architect Dan Kiley planned the grounds with Saarinen, echoing the Arch’s curve in reflecting ponds, walkways and the stairs down toward the riverfront. Walk the lawn instead of treating the Arch as a quick look from the car: the changing angles make its scale easier to read, and the paved paths are accessible.

Before the keystone was set, workers sealed a time capsule inside the Arch containing thousands of signatures gathered from the public. St. Louis mayor Alfonso Cervantes signed first. It is still inside the structure and cannot be removed while the Arch stands.
