TULSA, Oklahoma - Historic Route 66 has taken many turns in its 91 years. Five interstates eventually replaced much of the old road, but now many of the iconic stops on Route 66 are thriving.

"It's the trip of a lifetime; it's the most famous highway in the world," said Michael Wallis, author of "Route 66: The Mother Road."

For years, historic Route 66 took travelers to their destination; now, it is the destination.
 
"People like to go on adventures," said Route 66 Historian Jim Ross. "People like to be out. They like the freedom of the open road."
 
Oklahoma has the most miles of the iconic highway - with a string of attractions statewide. Near Foyil, Ed Galloway's Totem Pole Park draws visitors off the beaten path.

Back on the route to Catoosa, you can discover a giant concrete Blue Whale.
 
"It's unbelievable how many people stop here," said Blaine Davis.
 
Blain Davis' dad built the dock back in the '70s - when it was just a swimming hole.

The road still connects rural towns and cities - in fact many places, it still serves as Main Street.
 
"This road puts vehicular traffic, vehicular traffic in your state, in your county, in your town," said Michael Wallis, author of "Route 66: The Mother Road."

About 45,000 people travel along Route 66 through Oklahoma each year, and 30 percent of them are from other countries.
