Old Dominion expands in Maine

   Less-than-truckload carrier Old Dominion Freight Line has completed an expansion to its Portland, Maine, facility. 
   The renovated service center has 43 doors — more than 60-percent more doors than the original service center, Old Dominion said. The company entered Maine in 2005.
   The service center provides service throughout Maine, including Sanford, Scarborough, South Portland, Auburn, Lewiston, Bangor and Brunswick.
