A $190 million upgrade to a Southwest Arkansas sawmill is now complete. Federal and state leaders visited Dierks, Arkansas for the grand opening. …Governor Asa Hutchinson, U.S. Senator John Boozman, Congressman Bruce Westerman and other state and local leaders were on hand for the grand opening of the brand new Weyerhaeuser Lumber Mill. In 2015, the company announced plans to construct the upgraded facility to replace the former mill, which was originally built 100 years ago. Weyerhaeuser purchased the mill from the Dierks Forest Company in 1969. …The new mill has the capacity to produce about 380 million board feet of lumber per year.
