My family is planning a road trip from Omaha to Banff National Park this summer. Our first leg is Omaha to Calgary and we're trying to determine the best route. Google maps shows us taking I-29 to US-52, but we're concerned US-52 might be a 2 lane county road. I-90 looks better, but heads west in the US before we would turn north. Any thoughts? Your help is much appreciated!
