Starting off in Chicago, Illinois, you're kicking things off in the Windy City. From there, the route heads southwest through Illinois for roughly 300 miles, passing through places like Springfield, where you can soak up some history. Driving time for this leg? Maybe 5-6 hours if traffic's light, but hey, who rushes on a road trip.

Then you cross into Missouri, another solid chunk around 300 miles. St. Louis is the big highlight here, with its iconic arch towering over the skyline. The road winds through rolling hills and small towns; expect about 5 hours of drive time, depending on stops for pie or whatever.

Oklahoma comes next, with about 400 miles of flatlands and quirky roadside spots. Tulsa and Oklahoma City are the main urban stops, offering a mix of city vibes and open spaces. This section could take 6-7 hours straight through, but plan for more if you're detouring.

Texas Panhandle is shorter, just over 170 miles, slicing through Amarillo. It's quick, maybe 3 hours, but the vast plains make it feel endless in a good way.

New Mexico adds some desert flair for around 400 miles. Albuquerque and Santa Fe are key cities, with mountains creeping in. Driving wise, figure 6 hours, though the scenery might slow you down for photos.

Arizona's portion is epic, nearly 400 miles through canyons and forests. Flagstaff and the Grand Canyon area are must-sees; about 6 hours of driving, but the views are worth every minute.

Finally, California wraps it up with 300 miles to Los Angeles. Barstow and the Mojave Desert lead to the end at Santa Monica Pier. This last bit? Around 5 hours, ending with ocean breezes.

Overall, the whole trip takes 35-40 hours of pure driving, spread over days or weeks. Break it into segments like I did, and you'll avoid burnout. Remember, Route 66 isn't always straight highway anymore some parts are rerouted but the spirit's there. Pack your maps, or better yet, a good app, and hit the road for that cross country magic. Safe travels out their!
