St. Louis is creating its future and legacy through a $380 million CityArchRiver project that is transforming the national park surrounding the Gateway Arch and creating a new place to gather and celebrate in the heart of downtown. Scheduled for completion in summer of 2018, the improvements will provide unique and memorable event spaces throughout the grounds and the museum under the Arch.

Designed by world-renowned landscape architecture firm Michael Van Valkenburgh Associates, the project is scheduled to finalize in summer of 2018. When the project is complete, a new park built over the lanes of Interstate 70 will connect the Arch grounds directly to downtown St. Louis’ central business district. The new park will provide a pleasant and safe green space for pedestrians walking to the monument from the historic Old Courthouse, downtown hotels and the America’s Center Convention Complex.

A new underground-glass entrance will feature natural lighting and face the park over the highway. This west-facing entry plaza gives visitors an easier way to enter the Gateway Arch and its Museum of Westward Expansion. The park site will increase with 11 new acres, a renovated historic Old Courthouse and an expanded Museum of Westward Expansion. The museum will explore America’s western journey and the important role St. Louis and its people played in the growth of the United States.

New event space beneath the Arch will give groups an opportunity to use the museum as an off-site venue for events and performances. Guests can ride the elevators to the top of the nation’s tallest man-made monument for 30-mile views of St. Louis and the Mississippi River. Outside on the Arch’s park grounds more than five miles of new paths are under development along with additional green space and pedestrian and bike-friendly lanes to encourage activity in the park and along the Mississippi River.
