1935 - A series of severe earthquakes hits Helena causing extensive damage to the bank building. Cracked walls are propped up with timbers and braces inside and outside the building. 1938 - On June 17, a new bank building opens at what is now 400 North Park Ave. 1946 - In February, a second floor is added to accommodate the increased activity at the branch. 1988 - Lack of space in the old building and the advent of new banking technology indicate the need for a new building.
Ground is broken and construction begins on a new, uniquely designed building to house the branch.
Particular care is given to the design and location of the bank. 1990 - New Helena branch building opens for business. Located at Neill Avenue and Front Street, the new bank anchors the north end of the Last Chance Gulch pedestrian mall.
