The iconic Route 66 Begin Sign marks the eastern starting point of America’s historic “Mother Road” in downtown Chicago. Located at 78-98 E Adams St, just west of its intersection with S. Michigan Ave, this sign commemorates the original terminus established in 1926. Positioned across from the Art Institute of Chicago, it serves as a popular photo opportunity for travelers embarking on the 2,400-mile journey to Santa Monica, California. (route66travelinfo.com)
