Summary	0009946: Retracting bridges don't require support for construction, harmlessly deconstruct when checking support later
Description	A series of retracting bridges can be built without any means of support, each bridge accessed from another bridge. These bridges will "float" without any support for an arbitrary length of time, but activities that cause a "support check" (like retracting one of the bridges) will cause nearby unsupported bridges to spontaneously deconstruct. Presumably, retracting bridges should require support for designation/construction, should fail immediately if support is absent/removed, and should cause a cave-in instead of harmlessly deconstructing upon failure.
