I travel on a small portion of "The Mother Road" going to and from work. Here are a couple shots of what I see.

Birthplace and rise of Route 66
Modern-day shield used in California from 1956 – 74, when the road was decommissioned (note the black background cut off and the addition of the "US" designator)
Officially recognized as the birthplace of U.S. Route 66, it was in Springfield, Missouri on April 30, 1926 that officials first proposed the name of the new Chicago-to-Los Angeles highway. A placard in Park Central Square was dedicated to the city by the Route 66 Association of Missouri, and 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.
