This bill would change the law that sets the official boundary and name for the park at the Gateway Arch. It amends section 4(a) of the Act of May 17, 1954. The bill replaces the name the Jefferson National Expansion Memorial with Gateway Arch National Park, changes the listed area from one hundred acres to 102.18 acres, and updates the boundary map reference to a map titled Gateway Arch National Park Proposed Boundary Revision, numbered 366/189,627, dated August 2023. The bill was introduced in the Senate by Senator Richard Durbin on July 13, 2026, and referred to the Senate Committee on Energy and Natural Resources.
If enacted, the statutory name and the legal boundary of the park would be the name, acreage, and map listed in the amended law. People who visit, live near, or manage land close to the park would refer to the revised map and the 102.18 acre figure to know what land is officially inside the park. To see exact boundary lines, consult the August 2023 boundary map named in the bill.
