A bridge rail is a safety structure that runs along the edge of a bridge to enhance safety and prevent vehicles and pedestrians from falling off.

In open concrete bridge rails, the entire railing is made of concrete, with openings for rain water runoff. This kind of bridge rail is often used in flood-prone areas.
