First Interstate Center, Office building in downtown Billings, United States.

The First Interstate Center is a 272-foot (83 m) office tower in the Transwestern Plaza complex in downtown Billings, Montana, where it is the tallest building in the state and in the northern Rockies. It was designed by The Opus Group and completed in 1985. A sculpture, Pioneers Vision by Mike Capser, stands at the entrance.

The building was completed in 1985 and marked a turning point in Montana's architectural history. Upon its completion, it replaced the Crowne Plaza Hotel as the state's tallest structure.

The building's main tenant is First Interstate BancSystem, a Billings-based bank holding company, and its name appears on two large signs at the top of the façade. At the entrance stands Pioneers Vision, an allegorical sculpture by artist Mike Capser.

The tower stands within Transwestern Plaza, a four-building office complex in downtown Billings; the other three structures are five floors each. The entrance holds the allegorical sculpture Pioneers Vision by artist Mike Capser, worth a look before you continue. The building is working office space, so viewing is from the street and plaza rather than inside the floors.

The First Interstate Center is the only building in Montana that appears on the list of tallest buildings in the United States. It was designed by The Opus Group, and a sculpture titled Pioneers Vision by artist Mike Capser stands at the entrance.
