Something that cannot be seen from a car

There is a bridge in St John's that crosses over the outlet from a pond, about a km long and called aptly Long Pond. Car traffic over the bridge is usually pretty fast. And the bridge turns too, so people in the cars never actually see over the rail to much of the water below. But there is a sidewalk and you can lazily walk across the bridge, hanging your head over that rail, or pointing your camera down to the equally lazy water. Or lazy water most of the time.

Thus this during a time of lazy river this afternoon.
