50 years after it’s construction, the Gateway Arch is undergoing a renovation that will be complete by October
Anchored by the Gateway Arch and extending to the Old Courthouse, the Jefferson National Expansion Memorial is a 90 acre park on the bank of the Mississippi River.
As part of the CityArchRiver2015 project celebrating the 50th anniversary of the Gateway Arch, road construction is currently taking place around the major arteries of the Arch grounds and the Jefferson National Expansion Memorial. Information will continually update the closure and detour information to ensure our guests are able to visit throughout the construction period.
“Reimagining the Arch” is a half-hour prime-time special on the CityArchRiver project, which premiered June 23, 2014. The program describes the history of the Gateway Arch, how the CityArchRiver project will improve the visitor experience and what the future looks like for St. Louis, our national park and the riverfront.
VISITOR ALERT: As of Dec. 1 the Arch parking garage will be closed. The Chestnut, Market and Pine Street bridges are closed to pedestrian traffic. Walnut Street is the only point of entry to the Arch grounds from the city.
The north leg of the Gateway Arch is temporarily closed for maintenance. The south leg entrance will remain open and accessible during this time.
After parking in a downtown garage or parking lot walk to Walnut St. this is the only entrance into the park due to construction. This will lead you to the south leg.
