A placard in Park Central Square was dedicated to the city by the Route 66 Association of Missouri. Traces of the Mother Road are still visible in Downtown Springfield along Kearney Street, Glenstone Avenue, College and St. Louis streets and on Missouri 266 to Halltown. The red booths and gleaming chrome in mom and pop diners, the stone cottages of tourist courts and the many service stations along this route saw America fall in love with the automobile. Red's Giant Hamburg, said to be the birthplace of the drive-up order window, was located on the route.
