The trigger is placed as close to the bridge as possible so the hammer will trigger it right before it hits the bridge, allowing it to destroy the bridge (too close and the hammer hits the bridge and comes to a stop, which looks bad, too far away and the bridge pieces start falling too early which doesn't look right either. Took a bit of trial and error to get it just right).
So rider triggers plywood breakage which allows hammer to swing. Rider then must pass section of bridge in path of hammer before it swings. If the wait too long it destroys the bridge in front of them.
