You can start and stop your tour wherever you like but if you want to keep the story in context, we suggest you park your car on Broadway Street in front of the Oliver House and start with the Tour Introduction and then head for Stop 1: The High-Level Bridge.
Remember, always pull over and make sure your vehicle is out of the way of traffic when viewing the tour presentations. All of the roads used are public and traffic on some can be fairly heavy. Use caution, especially when pulling into traffic or slowing for a stop. Obey all posted speed limits and traffic regulations.
This tour is designed for at least two people, one to drive and one to operate the self-guided tour. Distracted driving is dangerous, DO NOT USE THIS TOUR ON YOUR OWN WHILE DRIVING—LET A PASSENGER MANAGE THE TOUR.
