The Post Office moved. The Ryan and Dakotah Hotels were made into apartments. The Methodist and Baptist Churches and the public library were razed. Griffith's and Norby's went out of business, along with dozens of smaller firms, and shoppers bypassed the old downtown as they hurried to Columbia Mall in the far south end. Fast food places and motels multiplied on the edges of town. Deaconess and St. Michael's hospitals grew into the United Hospital in a new Medical Park on South Columbia Road. Two overpasses spanned the railroad tracks. The University sprawled to the west side of the Coulee; the Grand Forks Air Force Base mushroomed; and the fertile, peaceful valley concealed underground missile sites.
