James Blvd. is a through street from one end of the town of Signal Mtn to the other. But the speed limit is 30 mph, so yes it has cars moving on it all day,.......but slowly. Also, the only house I'd be concerned about with very small children is a house on the corner of James and :Majestic Oaks. Otherwise, Majestic Oaks has its own neighborhood which is great for children.
Let me know if I can help with other questions about Signal Mountain!
