A northwest Iowa company will relocate and expand its Sioux Falls operation.

Interstates Companies is an electrical design, construction and control systems firm that's based in Sioux Center, Iowa.

Company officials say their expansion is expected to create 59 jobs in Sioux Falls over five years.

Interstates currently is located at 6009 South Sharon, but will move this fall to newly-acquired space at 4701 West Research Drive.

Company President Jack Woelber says the positions to be added will be in the fields of electrical engineering, computer programming, information technology and control system design.
