the historic route 66, which runs through williams, was completed in 1926. the establishment of route 66 was one of the major factors which contributed to the growth of the town. people who emigrated to the western part of the united states and tourists from different parts of the country often stopped and visited the city. as a consequence many motels were built, among them the motor hotel, located on the southeast corner of 4th street, and the 9 arizona motor hotel located on 315 w. route 66.
