Hard Light Bridge



A Hard Light Bridge (simply known as a Light Bridge,) is a semi-translucent solid made from natural sunlight beamed in from the Earth's surface. It can act as a bridge for the player, a shield against turrets and other hazards, or even a wall for more complex puzzles the player encounters later on.

The bridges span an infinite length or until stopped by another solid... Although the bridge is made of light, if one portion of the bridge is stopped by a solid object the rest will not continue as a beam of light normally would.

Trivia

 * Light Bridges first appeared in the Flash Version MapPack and then in Portal: Still Alive, but were more formally introduced in Portal 2.
 * The bridges in Portal: Still Alive are mostly functionally identical to the ones in Portal 2, but notably cannot be extended through portals (and do not block turrets).
 * The Hard Light Bridge was originally referred to as "Blue Plasma Wall" in Portal: The Flash Version
 * Despite GLaDOS warning the player that the Hard Light Bridge would [[Media:GLaDOS_sp_a2_bridge_intro01.wav|set their hair on fire if they rubbed their cheek on one]], rubbing any body part on the bridge actually does not cause any harm to the player.
