Winslow (Navajo: Béésh Sinil) is a city in Navajo County, Arizona, United States. According to the 2010 census, the population of the city is 9,655. It is approximately 57 miles (92 km) southeast of Flagstaff, 240 miles (390 km) west of Albuquerque, New Mexico, and 329 miles (529 km) southeast of Las Vegas.
Winslow was named for either Edward F. Winslow, president of St. Louis and San Francisco Rail Road, which owned half of the old Atlantic and Pacific Railroad, or Tom Winslow, a prospector who lived in the area.
The last Harvey House (La Posada Hotel), designed by Mary Colter, opened in 1930. The hotel closed in 1957 and was used by the Santa Fe Railway for offices. The railroad abandoned La Posada in 1994 and announced plans to tear it down. It was bought and restored by Allan Affeldt and it serves as a hotel.
U.S. Route 66 was originally routed through the city. A contract to build Interstate 40 as a bypass north of Winslow was awarded at the end of 1977. I-40 replaced U.S. Route 66 in Arizona in its entirety.
