You probably don't want to know whether a bridge is movable but whether 
it is high enough for your boat:

max_height=5m

To provide details for movable bridges, relations could be used:

member=<way xyz>
type=propset            # marks a group of properties
propset_type=temporary  # temporary change
max_height=0            # unlimited
time_on=09:00           # the proerties can only be made available
time_off=18:00          # during these opening hours

The having-to-wait property can simply be tagged as traffic_lights.
