As Salt Lake Union Pacific Railroad Station, it is listed on the National Register of Historic Places.

[6] The main lobby, no longer used by Amtrak (which has relocated to the Rio Grande Depot and later the Salt Lake City Intermodal Hub), serves as an entrance to The Gateway development.

It served the San Pedro, Los Angeles and Salt Lake and the Oregon Short Line when it was completed in 1909 and became wholly owned by Union Pacific in the 1920s.

[8] The sandstone building is in French Second Empire style, and includes a terrazzo floor and stained glass windows.

One ceiling mural “Driving The Golden Spike” by San Francisco artist John MacQuarrie in 1909, depicts the driving of the Golden Spike north of Salt Lake City at "Promontory Summit" signifying the completion of the first transcontinental railroad in 1869.

Additionally, the original slate roof was replaced by copper plates due to leaking problems.
