Old Dominion Freight Line Inc. announced on Monday that it has relocated its Des Moines Service Center to a 32-acre site at 6925 S.E. Four Mile Road in Ankeny. The center is more than twice the size of the company's old location, and is part of a $95 million investment that Old Dominion has committed to real estate purchases and expansion projects this year. The facility will employ 116 people and increase the capacity for moving large volumes of freight along Interstates 80 and 35, the company said in a release.
