What is the maximum clearance of the quot;Needles Eyequot; in the Black Hills of SD?|125673

We are planning a family trip to South Dakota later this year and I need to make sure we will be able to enjoy the same things I did when traveling there as a child. What are the heigth and width restrictions when traveling on the roads around Mt. Rushmore that have all the tunnels?

Several years ago we drove most of the roads in that area with a Chevy full size van, and had no problems with clearances. If you are driving a very large motor home, or pulling a big camping trailer, you may have a problem. Try the web site for the National Park Service, and click on that area. It might give you the info you are looking for. Have fun, it_s a beautiful area. Also, Devils Tower Wyoming is close.
