The Gateway Arch and grounds, the Old Courthouse, and the Museum of Westward Expansion are part of the Jefferson National Expansion Memorial in St. Louis.
A seamless unification of the diverse elements of this national park is in progress. In the past, the Old Courthouse was separated from the arch grounds by a highway. The park is being expanded over a section of the highway between Chestnut and Market streets so people will be able to walk from Fourth Street to the St. Louis Riverfront without having to cross intersections or climb any stairs.
This improvement will tie the Old Courthouse to the arch in a wheelchair-accessible fashion and provide improved safety for all visitors.
During construction, only Journey to the Top (tram) ticket-holders will be allowed entry into the facility. Restroom facilities inside the Gateway Arch are temporarily unavailable. However, there are restroom facilities in the Old Courthouse Visitor Center and portable restrooms are located at the north leg of the arch.
The arch has been closed but is now open and visitors can take the trams to the top. Tickets can be purchased in the Old Courthouse. Guests are directed to enter the arch through the north leg. The riverfront is open from the grand staircase to Choteau and more area is scheduled to open in May.
