 In 1948, US 66 was moved from downtown (it followed Glenstone Avenue, St. Louis Street, College Street, and Chestnut Expressway) onto a new alignment onto Kearney Street (now Route 744) and West Bypass and the old highway became the business route.With the completion of Interstate 44, Business I-44 was concurrent with it and US 66 was concurrent with I-44 (Kearney Street became, briefly, Bypass 66).By the late 1960s, Bypass 66 was deleted and the old bypass became the new Business 66 (the old Bus 66 was left as Business I-44 for a while, then turned over to the city).
