Old Dominion Freight Line announced a major expansion of its regional hub in Indianapolis.

ODFL will invest nearly $22 million to upgrade and enhance its existing facility at 3915 W. Morris St. and will hire 183 new employees by 2014. As part of the expansion, Old Dominion will be increasing the Indianapolis Service Center by more than 84,000 square feet - from 223 doors to 325 doors, making it one of the largest centers in the company's network.

Founded in 1934 and headquartered in Thomasville, N.C., Old Dominion is a less-than-truckload motor carrier that provides warehousing and distribution services for companies worldwide. Old Dominion operates 213 service centers nationwide and maintains several major regional hubs, including Indianapolis.

"Indianapolis is an important location for us, and this expanded facility will help us handle the increased freight volumes we've seen from customers," said David Congdon, Old Dominion's president and CEO. "As we continue to grow as a company, the expanded Indianapolis service center will play a vital role in how freight moves through the Midwestern region of the country."

The company in recent quarters has seen a dramatic growth in shipments, including a 14% increase in the total tonnage moved during the second quarter of 2011. To handle this growth, the company is planning to spend $100 million to $120 million this year to purchase real estate and expand facilities throughout its network.
