Route 66 used to run across northern Arizona where I-40 exists now, including Winslow, Holbrook, and Flagstaff.
Although Route 66 no longer appears on maps, many nostalgic people continue to long for the golden age Route 66 represented.
Along with the dozens of hotels, gas stations, and other businesses that died as new highways were built, there are gift shops and other businesses that work to keep the Route 66 legacy alive with souvenirs and memorabilia.
Many non-chain hotels (some look pretty scary) and other businesses remain and cater to the memory and tradition of this timeline of history.
Arizona is said to have the longest remaining stretch of Route 66.
