CitiMortgage Inc., a division of CitiBank, plans to expand its operations in August of this year when it moves into a new, 515,000-square-foot office building on Weldon Spring Road in Weldon Spring, MO. The 3-story property is being built on a piece of land located between Highway K and Highway 94, just west of the Persimmon Woods Golf Club. St. Louis-based Clayco Construction Co. is serving as the general contractor on the project, which broke ground in February of 2002.
