With golden shovels, the ground was officially broken for the new Allen Mitchell CPA building in downtown Washington Tuesday. Official construction will begin next week and is expected to be done by Thanksgiving. The office building will be up to 12,000 square feet. The brick building with big windows is being constructed at 123 East 2nd Street, at the former site of the Linda Lou’s Diner and Red Bear Daycare. The groundbreaking ceremony was held by the Washington Chamber of Commerce Chamber Ambassadors and Main Street Washington.
