As the characters run across the bridge hurriedly to lose their pursuers, namely crystalline creatures having taken the shape of those they knew in their homeworlds, they are outside of the Ancient facility. It is not just any facility though, looking down there is nothing but clouds, indicating the ruins are actually located on an island floating in the sky. Thus when the bridges breaks, all those who did not make it to the other side have absolutely no chances of survival.
The long abandoned facility itself seems to be divided into small islands and the only way to reach different places in it is to use the precarious bridges, clearly not of Ancient design and probably built by some adventurers in ancient times. At least, with the bridge broken the crystalline creatures have no choice but to give up and stop pursuing them—For the time being that is.
