Are you old enough to remember singer Bobby Troup’s song, “Route 66”, introduced 70 years ago in 1946? You can still get your kicks on that popular highway, but the lyrics are not quite correct. They say, “Well, it winds from Chicago to L.A.”

Actually, it does wind more than 2,400 miles from Chicago to L.A.. But it doesn’t end there. Route 66 continues another 15.7 miles to the Pacific Ocean beach at Santa Monica, California.

Another cross-country highway, Route I-10, takes a more southern route, and goes the 2,400 miles from Jacksonville, Florida, to Santa Monica.
