This brings into being a shadowy construct that people who believe in it can see clearly. The wizard automatically believes in the spell, others have to save versus spell to do so.
The bridge will support any weight put upon it, as long as that weight is put there by people who believe in the spell (physical objects dropped onto the bridge will fall through), even if there is no apparent support. The bridge can take on the form of a bridge, staircase or ladder.
The bridge lasts for the duration, but only as long as the wizard concentrates on it and has line of sight with it. The wizard can discontinue the spell at any time.
