Some very significant aesthetic changes came to Roy's Motel and Café in 1959: the February 1 erection of the towering neon boomerang sign visible for miles approaching Amboy; and the construction of the motel's new Mid-Century modern "inclined roof flying over a glassed wedge" guest reception and office theme building.
The 1972 opening of Interstate 40 in California, unconnected as well as a fair distance north of Amboy's section of Route 66, quite literally meant the overnight loss of business.
