Upon completion, the Arch was quickly cut off from the rest of the city by the heavily traveled I-44. The stainless-steel arch was designed and constructed as an urban renewal project that led to the loss of a colonial-era street grid, among hundreds of historic buildings. The Gateway Arch was completed in 1965 and at 630 feet tall and 630 feet wide, stands as the tallest structure in Missouri. The park is maintained by the National Park Service. The site was originally designated as a national memorial in 1935, but redesignated as a national park in 2018. The park consists of the Gateway Arch, a 91-acre park along the Mississippi River, the Old Courthouse, and a 140,000 square-foot museum. Specifically, it was a memorial to Thomas Jefferson, the pioneers, and Dred Scott.

The Gateway Arch National Park was designed to represent the role the city played in the United States expanding west in the 19th century. The Gateway Arch National Park, formerly known as the Jefferson National Expansion Memorial, is located near the starting point of the Lewis and Clark Expedition on the banks of the Mississippi River in downtown St. National Park-Landmark Pedestrian / Bicycle / Light Rail Transit Department of Transportation, National Park Service Louis, Bi-State Development Agency, CityArchRiver Foundation, U.S.
