Capitol Security Enhancements
The State of Missouri implemented new security detection systems at the South Carriage Tunnel public entrance in March 2024. This touchless security system enhances safety and allows Missouri Capitol Police to screen visitors and staff more efficiently.
General Public
The general public is able to access the Capitol Building through:
- South Carriage Tunnel Entrance: Monday – Friday from 7 am – 5 pm, Saturday and Sunday from 8 am – 4 pm (closed on New Year’s Day, Easter Sunday, Thanksgiving, Christmas, and on the authority of the Office of Administration Commissioner). This entrance faces High Street and easily accessible.
- East Basement Door: When the General Assembly is in Session after 5 pm in the Capitol, the general public may enter and be screened through the East Basement Door.
- ADA Access Point: The South Carriage Tunnel Entrance is ADA accessible during normal business hours. When the General Assembly is in Session after 5 pm, the East Basement Door is ADA accessible.

Missouri Capitol Police utilize walk-through security detection systems and X-ray conveyors for screening. These public entrances provided above are also used by special guests, media, lobbyists, and contract employees without electronic proximity cards and are subject to screening.

State Employees
Employees who work in the Capitol Building and those with regular business in the Capitol may be issued electronic key card credentials (proximity cards). They may enter secure entrances without being subject to search at the following entrances:
- West Basement - located by the Capitol cafeteria, facing Broadway Street
- Carriage East and Carriage West First Floor Doors – located on the south side of the Capitol beside the South Carriage Tunnel Entrance facing High Street.
- South Carriage Tunnel – proximity card readers are located on the X-ray machines. State employees entering at this checkpoint may use their proximity cards on this reader to verify current employment.
