#73 Pedestrian Tunnel

Pictured here is a pedestrian tunnel under a roadway. Similar to a culvert, a tunnel starts from an open space and ends in an open space. The difference, of course, is that a tunnel allows for the movement of people while a culvert allows for the movement of water. Tunnels such as this one allow for the safe passage of pedestrians under a road.
