The walkway through the center of the picnic area has a yellow dotted line painted in the center and there are a variety of Route 66 signs all along the walkway.
As we traveled from Oklahoma City, OK, to St. Louis, MO, on present day I-44 we have seen many businesses and community organizations celebrating Historic Route 66 -- colloquially known as the Main Street of America or the Mother Road. Route 66 was one of the original highways within the U.S. Highway System.
