City parking and west entrance for Gateway Arch National Park

Gateway Arch National Park does not operate parking facilities inside its boundaries, although four curb locations allow loading or unloading but not parking. Arrange your city parking separately before you drive to the park.

You will enter at the west entrance, which faces Fourth Street and the Old Courthouse. The Arch legs are exit only.
