I disagree.  As a driver, I would like to know that a bridge is movable, 
and specifically during which period it is likely to move, so that I can 
tell my routing application to avoid those bridges like the plague 
during those hours.  The "traffic light" property just isn't good 
enough, however, even just "bridge=movable" would be.
