Chicago, Illinois

Union Station is definitely a stop you don’t want to miss while traveling along Route 66. The station was built in 1925, and remains the third largest train terminal in America.

The station is active and remains extremely busy on weekdays. Over 120,000 people travel through Union Station every day.

When you stop by, be sure to visit the Great Hall, which is the oldest part of the station and one of the most beautiful. The Great Hall contains marble floors and marble walls, bronze torches to add to the touch, and Corinthian columns.

If you are hungry, this is the perfect spot as well. They have everything to munch on, from deli style sandwiches to pizza and anything in between.
