MOORHEAD — U.S. Bank has informed clients in a letter that the bank branch at 403 Center Ave., in Moorhead, will close on May 1. The letter, dated Feb. 1 and signed by Kathryn Astrup, a U.S. Bank district manager, states that client banking preferences and behaviors are changing and that affects how and where the bank operates. “As a result, we are consolidating some of our physical locations,” Astrup wrote in the letter. The Moorhead branch is one of about seven U.S. Bank branches in the Fargo-Moorhead area, including the downtown Fargo branch, which is about a mile away from the branch that is closing in Moorhead.
