After World War II, Winslow's growth slowed as technology reduced the railroad industry's manpower needs and town leaders resisted growth, leading the Santa Fe to expand diesel shops in Barstow, California, instead of Winslow. The opening of the Interstate 40 bypass in 1979 devastated downtown businesses, and the loss of passenger operations to Amtrak in 1971 continued to reduce railroad jobs, although railroads remained essential to freight hauling. The Santa Fe merged with the Burlington Northern Railroad in 1995, Winslow remained a division headquarters until those operations moved to Belen, New Mexico, in 2001, and the renamed BNSF Railway, purchased by Berkshire Hathaway in 2010, remained one of the town's largest employers. Winslow's economy later became more diversified, with a stable population of almost 10,000 and major employers including BNSF Railway, the Winslow Unified School District, Northland Pioneer College-Winslow Campus, the Little Colorado Medical Center, Winslow Indian Health Services, and an Arizona Department of Corrections facility south of town. The Winslow Municipal Airport, renamed the Winslow-Lindbergh Regional Airport in 1998, preserved its historic role in aviation, with daily operations run by Wiseman Aviation since 2007 and current users including the U.S. Forest Service, the U.S. military, Columbia Scientific Balloon Facility, medical transport services, the E&O Kitchen, recreational flyers, and the annual High Desert Fly-In. Winslow also continued as a border town where Hopi and Navajo people migrated for trade, employment, education, public services, and entertainment, while non-native residents also moved to Hopi and Navajo communities as traders, teachers, and medical workers.
