My son and his family will be returning from Florida to Michigan next weekend, taking I75-I24-I65-I69. Nashville, of course, will be a zoo. I've never taken 155/Briley Pkwy around the city, but it looks like it might avoid a lot of the 24/40/65 traffic. Would appreciate any thoughts. If this is a good route, what is the best way to get from I24 up to the parkway? Thanks in advance.
