What is the status of a bridge over a stream in golf rules?

In golf rules, a bridge over a stream is classified as an immovable obstruction. This distinction is important because immovable obstructions cannot be moved and if a player's stance or swing is obstructed by such an object, the player may take relief under the rules. Specifically, the player can determine the nearest point of relief and drop the ball in that area, free from interference by the obstruction.

The classification as an immovable obstruction implies that it is a permanent fixture that cannot be relocated without significant effort and is not intended to be moved during play. Understanding this status helps players to navigate the course effectively when encountering such obstructions, ensuring they adhere to the rules and maintain the pace of play.
