Then underground or undersea. A new tunnel in NYC for a subway line happens upon a portal and it’s only open when the other world has dug there. Even more concerning when the second world’s digging crew suddenly finds a subway train full of people in their newly dug tunnel.

Or to take a page from Planescape, perhaps the portals require a particular key to activate; a substance, signal, sound, particular thought, etc.
