Can you drive on it or is it only for walking

You can walk and drive over it

You can drive across but it is only 1 lane. So 1 car at a time and there is posted on each side of the bridge that you shouldn't climb down to the river and or waterfalls below.

There are small areas on either side that will accommodate a few cars for parking. There is a raised sidewalk on one side for walking on the bridge.
