America’s tallest man-made monument at 630 feet, the Gateway Arch has beckoned visitors for more than 50 years with its iconi ... c, awe-inspiring shape. The vision of renowned architect Eero Saarinen, the Arch commemorates Thomas Jefferson and St. Louis’ role in the westward expansion of the United States. Along with the Old Courthouse, it makes up the 90.96-acre Gateway Arch National Park (formerly Jefferson National Expansion Memorial). The CityArchRiver project, a $380-million plan to enhance the Arch visitor experience, is nearly complete. Visitors can now enjoy 11 new acres of parkland and over five miles of bike and walking paths, as well as the North Gateway, an outdoor natural amphitheater for events and performances. The redesigned Luther Ely Smith Square located between the Gateway Arch and Old Courthouse boasts an expanded park that stretches over the highway, leading to the Gateway Arch’s new west-facing entrance connecting the Arch directly to downtown St. Louis for the first time. The Museum at the Gateway Arch will celebrate its grand opening on July 3, 2018. Visitors to the Arch can enjoy the Tram Ride to the Top; watch the award-winning documentary Monument to the Dream, which details the Arch’s construction; take part in National Park Service interactive educational programs; and shop for memorabilia, gifts and even homemade fudge at The Arch Store, located in the Arch Visitor Center. Private events at the Gateway Arch will be available once again beginning Fall 2018. read more
