The station is located on the ground floor of the former Union Hotel, which was built in 1855 and is part of the Jefferson Landing State Historic Site.

[3] The entire Union Hotel building (including the station) was closed on October 2, 2019, due to concerns that its exterior masonry was no longer structurally sound after a bulge appeared in its north wall.

As of December 2021[update], funding for the project was waiting to be appropriated in the state's FY23 budget by the Missouri General Assembly.
