A photo of one of several bridges in New Zealand that serve simultaneously as a road bridge for cars and as a railroad bridge for trains. Notice on this photo the still shiny (due to frequent use) rails of the railroad line running over this bridge. A curiosity of such bridges in New Zealand is that they do not even have ordinary barriers or lights which would warn oncoming cars that another train is just approaching this bridge. Despite this, there are almost no accidents or collisions between trains and cars on these bridges. Drivers simply show the requisite respect for trains on them and cross them with extreme caution.
